There a lot of aftermarket fan clutches out there that just don't hold up. Purchase either a GM part or a Dorman replacement.

My 96' gmc cargo van 2500 series V8, 5.7??? is ALMOST over-heating as im driving it, then the guage drops too normal. stays that way for a few minutes and starts too creep up to the red line again, then...

I would be looking for a sticking thermostat, especially if it hasn't been changed for 2 or 3 years. Less likely would be the clutch fan not working properly. Hope this helps.

02 gmc envoy. was trowing codes for the accelerator position sensor, throttle position sensor, fuel tank pressure sensor, 1635 5volt circut 1, and fan clutch codes. Fan clutch replaced about 30 days...

Hi, the clutch itself is driven by a separate circuit. If anything is pulling down PCM power, it would have to be the fan relay coil. Perhaps the relay has shorted from the coil to the contact. Recommend you swap out the fan relay. Let me know if you have any questions, and thanks for using FixYa.

1 have 03 envoy,6cyl,have replaced viscouis fan,fan still runs a lot, dealer has checked twice all ok

Do you have the check engine light on? If a fault code of P1481 or P1484 is coming up with a scanner, the fan clutch is bad.

98 GMC jimmy started to slowly overheat after sitting for 15+ minutes. Got a little over 1/2 way mark in about 45 minutes then once I got going it cooled back down. Replaced radiator, radiator cap, and...

cooling fans. either electric or thermo clutch(heat tightens up a coil spring to make it spin faster as needed) If it has electric fans then they may be going bad and not spinnig fast enough. if its the mechanical type with the thermo clutch, its not engaging strongly enough. much like and old stick shift car with a bad clutch.

you need a special tool(fan clutch removal tool), autozone will let you borrow for free with a security deposit. Make sure engine is cold. Remove negative battery terminal1. Drain all coolant, and remove top radiator hose. 2.remove fan shroud on radiator(transmission cooler lines may need to be disconnected and slide off the fan clutch harness on the RH side). 3.loosen fan bolts on fan clutch. 4. use fan clutch tool to unbolt main fan clutch bolt. 5. Unplug fan clutch electrical harness. Reverse to install!! NOTE: You may need to reprogram the ECU if you install a new fan clutch and your check engine light comes on. Make sure you refill coolant with GMs recommended dexron coolant. Hopefully this helps....please rate....thanks!!

P0172 and P0128 Error Code 2003 Trailblazer 4WD

PO172 means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). I would replace the thermostat first. The computer could be injecting too much fuel because it thinks it never gets to operating temperature. That may keep the light off.
