Note the drive belt routing, usually there is a sticker under the hood with the routing. using the right socket and a breaker bar, rotate the drive belt tensioner clockwise to relieve tension. remove belt and slowly release breaker bar tesnsion. for V8, Install on all pulleys except generator, loosen tension and install on generator. for 4.2L install belt over all pulleys except tensioner, relieve tension and install over tensioner, slowly release breaker bar tension.

SOURCE: how to replace a serpentine belt on a 2004

  1. Lift the car so you can work from underneath when needed.
  2. Disconnect the battery . Just to be safe.
  3. Take the serpentine belt off.
  4. Remove the alternator.
  5. Remove the A/C compressor. (You can do it without removing, but it's a royal PITA... LOL) Don't unhook the lines, just unbolt and move out of the way.
  6. Remove the worn tensioner from t he block. (You need to unbolt the pulley first to get to all the tensioner bolts)

2004 trailblazer is running like **** blower on defrost makes car wanna stall out and lights flicker what could this be

You would need to know for sure that the radiator is full and that the serpentine belt is not slipping.
The water pump could have died and that could affect the belt and the alternator.

How to check a serpentine belt on a 2004 chevy trailblazer

What I do to check the belt is to look at the belt and see if it has cracks on the inside. The small ribs or grooves in the belt will have small cracks when the belt needs replaced.

I changed the serpentine belt and now there is a humming noise

If you've double checked to make sure belt on properly, you'll have to identify which wheel (pulley) is making noise and check it for any debris that may have built up on it, or possibility of bearing failure in that part. Was it not noticeable with old belt, or was old belt pretty noisy, and that's why it was changed?
