Check the connector on the fan clutch. Make sure a pin didn't get pushed out the back side of the harness that plugs into fan clutch.

How to replace water pump on 4.2 liter 2004 trail blazer LS


4 bolts hold the shroud on. 2 on bottom,2 on top. Leave on in on the top until you remove the clutch fan. Clutch fans are a pain to get off with out the right tools. Once off, remove the bolt from the shroud and pull them out together. Remove the serpentine belt. Remove the pump.

2002 CHEVY TRAILBLAZER keeps setting a FAN Speed Sensor Code.


CJ, this is very common for the I6 engines in TB's and Envoys. You need a new fan clutch. Triple check the wire connectors first, located on the top of the radiator on the drivers side, make sure those are in tact first. Then replace the fan clutch. Might as well do your water pump and serpentine belt while you're in there.

2004 trailblazer, 2 wheel drive. Code P0526, fan clutch circuit. Replaced fan clutch. Still code P0526. Wiring ok. Check Engine Light still on.


A couple of things come to mind. Double check the wiring at the fan clutch, check the whole harness, there is a known problem wth chaffing there. Is it a Dorman brand fan clutch? These have been known to be bad out of the box. The other thing that could be wrong is the actual speed sensor on the new fan clutch. Hope some of this helps.

My trailblazer is making a grinding noise where the fan goes into the motor and it is loose


the fan clutch may be bad, very common, but check the water pump also. Fan clutch failure is common, you may be ahead to replace that if the pump is bad.

TSB#05-06-02-012B: Service Engine Soon (SES) or Check Engine Light On, DTC P0480, P0526/P1481/P1484 Set (Replace Engine Cooling Fan Wiring Harness) - (Oct 19, 2006)
Subject:
Service Engine Soon (SES) or Check Engine Light On,
DTC P0480/P0526/P1481/P1484 Set (Replace Engine Cooling Fan Wiring Harness)
Condition
Some customers may comment that the Service Engine Soon (SES) or Check Engine light is illuminated. This condition may be intermittent and upon investigation, the technician may find either DTC P0480, P0526, P1481 or P1484 set.

Cause
This condition may be caused by the cooling fan harness chaffing against the plastic guide it routes through. This
contact may damage the insulation of the wires enclosed in that harness.

Correction
Replace the engine cooling fan harness using the procedure listed below.

1. Remove the cooling fan. Refer to the Cooling Fan and Shroud Replacement procedure in the Engine Cooling sub-section of SI.

2. Place the cooling fan assembly on a bench.
Disconnect the harness electrical connector from the cooling fan clutch.

3. Remove the harness from the plastic guide while feeding the wires out of the slot.

4. Before installing the new harness, wrap the affected area on the wires with electrical tape to keep the protective sleeve in place. Be sure to keep the tape approximately 25 mm (1 in) away from the connector so the wires can be fed into the slot.

5. Feed the wires into the slot and install the harness to the plastic guide.

6. Connect the harness electrical connector to the cooling fan clutch.

7. Install the cooling fan. Refer to the Cooling Fan and Shroud Replacement procedure in the Engine Cooling sub-section of SI.
