I have a 2004 trailblazer and it keeps over heating at stop lights or while driving slow. I have replaced the thermostat and water pump, but this issue still shows up. It is fine while driving down the highway at 55-65 mph. I have also cleaned the radiator and blew through the fins to clean out the dirt and bugs. Not sure if clutch is operating correctly. How can one tell if it is and are these electric? I know there are approx 5 wires running to the front of the clutch, but not sure if this gets a voltage signal to engage the clutch fan. Any ideas?

Fans don't go bad unless they are missing blades. Fan clutches will make a vehicle overheat if they don't operate properly.Fan clutch.

2003 chevrolet trailblazer 4.2 problem code p1481

See attached picture for location of temp. sensor, but that code has nothing to do with temp sensor. The speed of the fan does not agree with the commanded speed, you may have another bad fan clutch.

Need to take fan off a 97 vortec motor

First. remove the bolts that hold the upper half of the fan shroud and remove the fan shroud upper section. Then use a fan clutch removal tool (see picture below) to hold the water pump and remove the fan from the water pump.

Note: Many aftermarket parts suppliers will "loan" or "rent" you the tools for this job. They usually make you pay the price of the tool up-front, but will give you a full refund when the tool is returned to the store.

How do I know If my fan cluth is bad in my 98 chevy Express van

If the fan wobbles or spins at all it's bad. If you try to spin it, it should stop as soon as you stop pushing on it.

Fan clutch is wobbly and making a noice

You should replace the fan clutch. Unbolt it from the water pump and pull cluth and fan out together. Unbolt fan blade making note of blade angles, so you install it right on new clutch. Bolt fan on new clutch and reinstall unit. When the clutch has play or wobbles it is time to replace it before it breaks off and goes thru the radiator.
