02 trailblazer ltz service engine reduced power light comes on --replaced fan clutch water pump help?
Use an OBD2 code scanner to find out what's wrong with your vehicle. It will tell you what's wrong and let you clear the code when you're done. If the problem hasn't been taken care of, the computer will set the code again. BTW, why would you replace parts that weren't causing a problem?

It is threaded onto the pump shaft. You need a special tool that will hold the pulley and a large wrench for the bolt behind the fan. you can rent the tool at napa. These tools can be rented at any Autozone as well. Ask for the fan clutch wrench set. One Method: If you don't have access to NAPA… or one of those tools, here's another suggestion. Leave the serpentine belt on, put a large wrench on the nut and tap it with a hammer to break it loose. The belt will hold enough tension on the water pump pulley to allow most of them to be broke loose. Another Method: Here's my method: remove the water pump with the fan attached. be especially careful not to damage the radiator fins. put the whole assembly on a work bench and place a strap wrench (they're cheap and very useful for other projects) on the pulley and a big crescent on the fan nut. that nut is a right hand thread and isn't on there very tight so it won't take much to break it loose. More Information: I just did my water pump on my 98 Silverado. It should only take about a half hour to do the job from start to finish if you have the right tools. I left everything on the water pump, but pulled the shroud off for more room, then got the right tool from NAPA, (loan tools) to get the clutch fan off the pump. . I had the same problem . Fooled around with it for a while (several hours) then asked someone and it was simple. Thread 2 nuts down on the bolt. Tighten them together. Put a wrench on the bottom one. Turn counterclockwise.

You will need a large wrench, and a special holder for the waterpump's pulley. I can't remember the size wrench- about a 30MM- or1&1/4" to loosen and remove the hub. It has right hand threads. 1 7/16" or 1 1/2" open end wrench will fit. A large adjustable willalso work.
If it is like a dodge van the clutch fan has a large nut on the back of it you need to trun it counter clockwise to remove it,it might have locktight on it so you will need to leave the belt on and apply preasure to it as you turn the nut and try some heat some times that will work,be carefull not t…o bend the fan they are balanced,a bent fan will wear out the new waterpump. It is exactly the same as the van. (MORE)
First, lubricate the large nut on the fan clutch with wd-40 or equivalent. Let it soak overnight if you have time. Then you will need a strap wrench to wrap around the pulleys to hold them from turning. Next, take an open end wrench and loosen the nut. The threads are left-handed, so turn opposite o…f normal way. Autozone can probably loan you the proper tools for free, just pay a refundable deposit. Good luck!. use a strap wrench to keep pulleys still. nut is left-handed,ie,backwards.use wd-40. (MORE)
the pump is driven off of a accessory belt,YES,jack the car up,and look underneath,you will see a pipe mounted to the oil pan and the back of the block sometimes,unbolt it,and pull the pipe out of the waterpump,now look up at the water pump and you will see 3 bolts holding it on,take them out,and fi…sh that thing out of there!!!there is a O-ring that goes on the pipe,so be sure to replace it!

Replaced radiator fan fan shroud fan clutch in your 2002 trailblazer v6 right away and still the engine sounds like a jet engine and the idle seems to always run high wth loud soundofair limitedpower?
\n. \n Answer \n. \n. \nI had this same problem and it had nothing to do with the fan but the transmission. The dealership did some computer upgrade and fixed the problem\n. \n. \nThe older model years should have had a PCM re-flash from the dealer. If this problem re-occurs after the fan…-clutch is replaced then a reflash is needed. There are many cases where the reflash is the only correstion needed and the dealer is the only place it can be done unless you know a PCM tuner shop. (MORE)
Answer . I used a 12 inch crescent tool turning it counterclockwise and holding the water pump pulley in place with a 13mm tool. I hope this help. Good luck.
Service engine soon light on after you replaced drive belt and Power steering pump drive belt at Pep-boys are they responsible for rechecking engine codes?
Answer . "Service engine soon", usually just means that it's time to change the oil. If you know that particular service has been completed recently, perhaps the technician didn't clear the timer.

02 ltz Trailblazer and the Heating and AC fan will not work What is the problem and is it easy to fix for a novice?
Answer . \nCheck for a blown fuse first. If the fuse is OK, then the blower motor resistor pack or the blower motor itself may be bad.
Repair shop said that the jet engine noise on your 02 TB 90K comes from the power steering pump Sounds like it too Could this be possible Is there a chance that it's not the fan clutch making noice?
\n. \n Answer 1, Noise \n. \nNo,not the fan clutch or power steering pump for that matter. Had same touble with my 2000 Buick. Turned out to be, of all things, the front struts not properly lubricated. Dealer dismantled the top of the struts and used a very heavy grease all over. Put it back t…ogether and NO noise! \nNOW, this is assuming you only experience the noise when turning the steering wheel!\n. \n. \n Answer 2, Additional Input \n. \nThe simple answer to your question, as asked, is YES, it possible that the fan clutch, OR ANY OF THE FOLLOWING COMPONENTS could be causing the noise.\n. \nThere are MANY things which can cause many different noises. From your question, "...jet engine noise..." I have to assume you mean like the high pitched "whine" made by high speed turbine blades. This suggests something which is turning at high speed.\n. \nThis means probably something ON, not in, the engine. The components which commonly can cause a high pitched whine include:\n. \n1. Power steering pump bearings, vanes, or pulley,\n. \n2. Alternator bearings or pulley,\n. \n3. The air pump [for the pollution control system] bearings, vanes, or pully,\n. \n4. The belt, or belts, which drive these components,\n. \n5. Air conditioner clutch [bearings or a loose fragment trapped inside the assembly] or pulley,\n. \n6. If operating when the noise is present, the air conditioner compressor itself [bearings, piston/cylinder,etc.],\n. \n7. The radiator fan clutch or pulley [if your vehicle uses a belt driven fan] OR, if your vehicle has an electric radiator \nfan,\n. \n8. The bearings in the electric radiator fan motor and,\n. \n9. Even the heat/AC blower fan bearings [IF it is operating when the noise is heard].\n. \nAgain, the simple answer to your question is YES, it is possible that any one or more of these components could be the source of the noise, AND there may be others which I have not thought of.\n. \nBelt and/or pulley noises are usually the result of misadjustment and/or misalignment of the pulleys. Occasionally, an improper or wrong fitting belt can also cause similar noise.\n. \nAs mentioned in answer 1, it is important to note whether the sound occurs all the time, or intermittantly, as if only when making a hard or tight turn. If it occurs ONLY when turning, the problem is probably related to drive belt tension, or as experienced by the responder in answer 1, a suspension and/or steering component, an improperly lubricated strut bushing.\n. \nTo AVOID unnecessarily replacing VERY EXPENSIVE components, it is IMPERATIVE that the SOURCE of the noise is CORRECTLY IDENTIFIED BEFORE YOU replace anything.\n. \nI strongly suggest that you get another, or even two, opinion from a PROFESSIONAL MECHANIC(S) before paying to repair anything.\n. \nIt is better to pay to get a PROPER DIAGNOSIS, and then to pay for a single, proper repair, than to spend a lot of money only to then find out that the problem is still there.\n. \n. \n. \n Reply \nThanks for your quick answers. The car does make the "jet-engin" noise as soon as I hit the gas. You can even hear it while the car is idling. Checking around on the internet I have found atleast 50 people with the same problem & they were all upset & demanded a recall by GM because of it. They also had in common that their cars were fixed by replacing their fan clutches. But I guess I should take it to a certified GM shop & have them check it out. If anyone has anymore suggestions I would love to hear them. TY. Martin. (MORE)
Not all the fan clutch nuts are left hand thread some are right handed. It states which type you have on the top of the radiator shroud. Answer Put a rag on the pulley and wrap your chain wrench around it to hold on and keep the pump from turning when you put your monster adjustable wrench on t…he clutch and turn it off. Sears sells a strap wrench (Part #45570) that works really well for holding the fan pulley. (MORE)
\n. \n Fan Clutch \n. \nThere are usually 4 bolts that hold the clutch to the water pump shaft. It's often an awkward process to hold the shaft from turning while you remove the bolts, but it can be done.\n. \nThere is a tool available to assist in holding the shaft in place. Most auto parts… store will allow you to "borrow" the tool if they have one available.\nI used a pipe wrench when I did it, but the clearance is difficult.\n \nAs a note: when you replace the water pump, replace the thermostat at the same time as you will have the needed clearance to reach it.

Answer . \nfan clutch screws off water pump\nfan pump has left hand thread so to remove you need to turn clockwise
You are replacing the water pump on your 1994 Safari everything was going fine until you got to the fan you got the 4 nuts off but the fan clutch won't come off any suggestions No other bolts?
you need to put the 4 bolts back in the pulley there are four little holes in the pulley were a special holding tool goes then put a wrench on the clutch and loosen, some of them fans had reverse threads so be careful. hope this helps you!
Answer . There are too many codes to list. You must get the code read at a service center to figure out what the problem is.. The single most important thing to remember is that if a check engine light is flashing you must shut the vehicle down immediatley. . Autozone reads codes for free.… (MORE)
Same happened to me. It would come on, then a few days later it would go off. Took it to Jiffy Lube for an oil change, and they came in and told me that the connector to the light was loose. So they pluged it back in. And its fine now. I believe Auto Zone does a free diagnostic test. You could do th…at to see if anything is wrong first. Hope that helps (MORE)
fix the problem and the light goes off its sensors or cat converter but if it runs good don't worry drive it there is nothing really wrong with it light just stays on
Answer . if you do not have no experience in fixing car, do not do it
A few weekends ago I had to replace the fan clutch on my '06 Trailblazer EXT LS. In addition to getting the P0495 code from the check engine light, when I rev'd it up it sounded like a jet engine. Instructions: http://www.diystew.com/2006-trailblazer/
key on engine off push gas pedal to the floor three times wait for it to flashthen your done
The reduced engine power light comes on to make you get your problem fixed ASAP! It may be a rich code being picked up by an O2 sensor but whatever it is, the code must be diagnosed and cleared. You may disconnect your battery for 15 minutes to clear the code to see if it resets but if you are no…t mechanically inclined then you should go to a reputable GM dealership to get it fixed. (MORE)
Service engine lights need to be read with a code reader for your make and model. If the problem has already been fixed, you can reset the light by removing the appropriate fuse, or disconnecting the negative battery terminal for at least 30 seconds.
Alot of times your local auto parts store will have free check engine light reader. Make sure you attend to the problem if one exsists but they should be able to reset it for you at no charge (Autozone for example). Not sure with the trailblazer but sometimes if you disconnect your battery for a hou…r or so it will reset the computer.. Auto part stores scan for CEL (check engine light). The service light is different. It usually means your vehicle has hit a set number of miles for a certain service recommended by the manufacturer. I'm not sure about the trailblazer, but my silverado has a reset procedure. Turn key on, pump gas pedal 5 times, when the light flashes press the odometer reset button. Trailblazer might be different, but probably something close. (MORE)
The fan clutch on 2003 trailblazer sounds like a jet engine the dealer tells me even if i replace it they will have to reprogram it is this true or can i do it myself?
You can absolutely replace the fan clutch on your 2003 Trailblazeryourself. The clutch does not have to be reprogrammed but you dohave to wait until the vehicle is completely cool before you beginwork. Just remember to re-torque the fan bolts as specified in yourmanual.
How do you get the clutch fan off the water pump to replace the water pump on a 86 Ford f150 straight 6?
you need to rent a 'clutch fan removal tool' as regular wrenches are too thick.....Serpentine belt engines have a standard thread while v belt engines have reverse threads
How do you replace the water pump on jeep 5.2 engine is the nut that holds the fan clutch on right or left hand thread?
As you face the engine, you need to turn the nut in a counter-clockwise direction.
There are pages and pages and items that can cause a check engine light. You need to have it checked for codes with a scan tool. After repair light can be shut off with scan tool.

You need to put a block of wood against the blade of the fan in a way as to prevent the fan from turning. It is advised to wrap this block in an old towel or large rag to protect the fan blade.
You have an 02 trailblazer and when you start the engine the fan clutch engages and it blows normally then when temperature rise up it disengages until its too hot around 250 F?
It should throw a code and cause your check engine light to come on? The code will tell the story. Things that are common problems with these symptoms would be: Thermostat - Usually fails in the open position but not always. Fan clutch - It should go in to full lock up at increased engine t…emps and sound like a jet engine roar when you drive it . The roar should go away when the temps drop. PCM - May need reprogramming as it controls the fan clutch Water pump - The fan blade will feel loose and have a wiggle to it with hand force. www.trailvoy.com All the answers for your Trailblazer from true enthusiasts!.

Auto Zone will check your computer codes for FREE.... It maybe a bad coil pack.
Get the Trouble code read then have it reset at the same time. You can also disconnect the negative battery terminal for 10 minutes and it will reset. If you have not fixed the problem the code will set again causing your check engine light to come back on.
Either the bulb is bad or a previous owner disconnected it because it would not go out with the vehicle running. hOW DO YOU GET TO THE BULB??
First, the neg. battery cable should be removed from the battery, the appropriate belts should be removed, the rad should be drained to at least as low as the bottom of the water pump's lowest point, and the top rad hose should be removed. Then the fan shroud bolts should be removed. The fan and clu…tch should be attached to the water pump hub by a large threaded nut. If the fan clutch itself needs to be dissassembled, or if the water pump pulley bolts can't be accessed with the fan present, then wedge a prybar or long screwdriver between the pulley bolts to prevent the fan turning and, using the appropriate size wrench, turn the large nut counterclockwise to loosen and remove it. If the water pump pulley bolts can be accessed then remove them and pull out the fan assembly and the fan shroud together. Installation is the reverse of removal. Don't forget to put the shroud and fan back in together. (MORE)
Check the gas pedal. My daughters engine power reduced message came on and we thought it was the battery and alternator.

We had it changed and the sensor changed and… the message went off her display and has been running ever since. H (MORE)
Reduce engine light comes on and the car stops accelerating the engine service light is on continuously?
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on,… too. To determine the cause, the vehicle will need to be taken to a parts store or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

Just did this myself on my 2002 TB. Not sure how old your question is... but for future reference (since I don't see any other related help out there for this thing, most people just change out the entire fan clutch): Step 1: Loosen the bolts that attach the Radiator Fan to the Fan Clutch. … So... you're standing in front of the vehicle, looking down at the engine. There are 4 bolts. It doesn't take much to loosen them, and then pull them out by hand. Put them in a safe place. (Sip a beer at this point) This allows you to gently nudge the plastic fan blade assembly off the clutch and towards the engine. It's ok, it worked just fine. Just don't be rough with the fan blades, you don't want to break anything. Step 2: Loosen the bolts attaching the Fan Shroud to the Radiator Assembly. Two bolts... notice in the middle of the shroud, there's a little thing that hooks onto the Radiator Assembly. Once unbolted, you're going to have to shimmy and lift this shroud up and backwards into the same area that the fan blade is now resting. Towards the engine, and away from the Radiator. (TRICK: Undo the Radiator Return Hose on the Left side, the big fat thing... you will lose some coolant, make sure there are no cats in the area. And wash the driveway down after you;'re done so you don't kill any kittens. I had it undone only long enough to work the shroud off. Then I hooked it all back up.) WARNING:!!!!!! THE RADIATOR IS NOW UNPROTECTED... EITHER COVER IT WITH CARDBOARD, OR BE SUPER CAREFUL. NO TOOLS CLOSE TO IT, OTHERWISE YOU'LL PUNCTURE IT AND HATE YOURSELF UNTIL NEXT PAYDAY. AND THEN HATE YOURSELF SOME MORE. (Didn't actually do it, but I've read some nasty stories of folks screwing up here) STEP 3: You can now readily see the Fan Clutch Wiring Harness. Mounted to this spindle arm, and the other end to the Fan Shroud. Unhook the Fan Shroud side, and pop the plastic fastener that's securing it. I lost it in the engine, so I used a zip tie to resecure it later.There's two clips that also keep it secured, you can pinch those on the inside to loosen. STEP 4: Moving your attention to the Fan Clutch side of the harness. You can move the spindle arm to get at the harness easier. NO big deal. Carefully feed each individual wire that's on the Fan Clutch side through the slot on the spindle arm. Once that's done, you can yank the entire Harness out of there... if you've been throwing codes and seeing the reduced power light, you'll notice that the wires are either frayed, or one of them has disconnected from the wire harness adapter all together. STEP 5: Reverse the process with your $100 brand spanking wire harness. Getting the new one on is pretty quick, with the spindle arm slowing you down somewhat. Be careful here, you don't want to pull out any wires. STEP 6: Once your harness is attached and secured to both the Spindle Arm side and the Fan Shroud side, carefully remount everything. STEP 7: Breathe... take a swig of beer, you haven't screwed up the Radiator, and the hard parts are all but done. The shroud show now be attached to the Radiator Assembly. Align your Radiator Fan to the holes in the Fan Clutch. Hand feed, then tighten in cross pattern. DOn't over tighten. But make it secure. STEP 8: Remove all tools and recheck everything. Good? Done. STEP 9: Start your engine. The Fan clutch will be engaged and you'll notice the airflow coming off the FAN. This is normal. Go to your OBD reader and clear your codes (Amazon, cheap...) Close your hood. Take a drive. When your engine is at operating temp, you'll notice that you don't sound like a jet engine. STEP 10: after a short test drive... return home. Wash your dirty grimy hands. Enjoy your beer. Took me an hour and half to do this. (MORE)
A problem has been detected with the Anti-lock Brake System : It could be a fuse , a sensor , or some other problem As long as the red " BRAKE " light in your dash is not on , you still have " normal " brakes
Why would the check engine light come on if you just replace the water pump the upper and lower hose the thermostat and clutch on a 1997 ford explorer took to auto zone say it could be anything?
You need to have the ECU scanned with the OBD2 scan tool to retrieve the code that has been set. This code will tell you what part is being affected but not necessarily the defective part. To find the real problem you need diagnostic skills.
