20 Most Recent 2002 Chevrolet TrailBlazer Questions & Answers

If you are asking how to do this, it is not easy, it is very complex and takes a long time. The big points: Drain the coolant, disconnect battery, take off the intake manifold, take of the exhaust manifold, remove the head, clean the head and check for warp and cracks, clean the block and remove all debris from cylinders, install gasket, put head back on, put manifolds back on, replace coolant, change oil, connect the battery. You may have issues with bolts that break or strip out the block, you should send the head in to be checked, the valves and springs should be checked and those seals replaced, you need special tools and reference materials.

Hi, first, keep this diagram around as you will need it to route the serpentine belt when you reinstall it. There may also be a diagram under the hood by the radiator.

When the A/C clutch is not engaged is the space between the pulley and the clutch plate with in specs?

You'll need a helper for this. Refill the reservoir.
**Keep the blazer in park with the E brake on.**
It might help if you raise the front end onto axle stands. Run the engine so the power steering is active. Get you helper to turn the steering from lock to lock, hard left to hard right and back again. Do this 2 or 3 times. While they do this have a look at all the pipe work you can see, WEAR SAFETY GOGGLES if your under the car. Working the steering will show where the system is leaking.

If you have a clear view of that cylinder, look at that area in the dark to see if you can find any sign of sparking that would indicate a failure of the insulation on the wires or the coil.

It sounds like a linkage in steering column or at transmission has come undone or broken. You should be able to see the arm that comes down from the steering column to the transmission if you crawl under with a light. That's could be an an easy fix, but getting in the steering column is best left to professionals. Hope that helps.
