Question about 2002 Chevrolet TrailBlazer

1 Answer

Power steering went out on a 2002 trailblazer. the serpentine belt was slipping off so I replaced the serpentine belt and pulley tensioner, still out. Pulled the steering pump, pulley shaft was broken. replaced the steering pump and still no power steering. No fluid leaks and level is topped off. Any thoughts? is there a relay or fuse to reset?

Have you checked your tie rods? Possibility one is either bent or broken, I've seen it before on TB's. That pulley shaft is a common problem to break, especially when cold out. PS pumps/pulley shafts and tie rods will snap if doing donuts in the snow with the steering wheel cranked, or off-roading. The PS is completely mechanical, no fuses or relays.

How do I replace the Airconditioning/power steering belt on a Grand marquis, Mercury(1992)? please show me in a diagram or print somehow


Move the Grand Marquis's serpentine belt tensioner off the serpentine belt with the serpentine belt tool. Pull the belt of the remaining pulleys by hand. Take the belt out of the engine well. Wrap the new belt around the bottom portion of the crankshaft pulley. Follow the belt routing diagram to route the belt over each remaining pulley until only the tensioner remains. Move the Grand Marquis's serpentine belt tensioner aside once more and slip the belt onto the tensioner pulley.Hold the belt in place with one hand while you move the tensioner slowly back into position with the other. Here you can fine the quality AC parts http://www.1airconditioning.com/ac_compresor.htm

We just replaced the serpentine belt yesterday, after starting the car realized that the steering wasnt working, checked under the hood and the new serpentine belt is now broken, looks like it snapped


Maybe one of the drive pulleys has become seized. Sometimes the air conditioning compressor can be become seized and this puts a lot of strain on the serpentine belt. Did you take the tension of the tensioner pulley to slip the belt on or did you force it on. If you put it on with brute force the chances are that you did real damage to the belt. Check that all the pulleys turn (by hand). Check out how to take the tension off the tensioner pulley (often it is just a matter of putting a spanner on the pulley's central nut and rotating the mechanism anticlockwise against the spring tension. The belt should slip on without any effort if the tensioner is held back. Once on the tensioner can be released. The tension on the belt should be enough so that it is difficult to twist the belt, between pulleys, beyond about 90 degrees.

Ho is the power steering belt on 2002 chrysler


Click on the following direct Link. It has the Belt Diagrams you will need, complete with Removal Diagrams and Directions. It also has numerous other helpful diagrams for use.

Standard Rules to Removal the Serpentine Belt with a Tensioner:
1. Find the Tensioner(s). (See Diagrams on Link)
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating the Tensioner Pulley/Arm - moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.
4. DO NOT quickly release the Tensioner, but gently allow the Tensioner to rest in its closed position.

Standard Rules for Installing the Serpentine Belt with Tensioners:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them

When my serpentine belt broke three times the problem was diagnosed as the power steering pump. Why wasn't this diagnosed when the tensioner was replaced. I am now replacing the power steering pump and...


That is a valid question, but you should ask the shop that worked on it. Also do you know that the power steering pump will cure the problem? This remains to be seen....You can check one thing though...Look at the belt/pulley arrangement from the side. any pulley that is not exactly in line with all others, and any wobbling pulley is suspect. Serpentine belts are far less forgiving of these items than were "v" belts.
Good luck

Power steering pump


your serpentine drive belt could be slipping over your power steering pump. Sounds like a premature failure from your pump. This is not an easy fix depending on the location of the pump itself. Remove your serpentine belt, locate the pump and pulley. Try to spin the pulley by hand. If there is alot of tension, your pump may need replacing. If not, try replacing the belt and check your belt tensioner for looseness.
