2005 Chev. express 5.3L . Idle pully replacement

Firstb remove the serp belt, detiontioning the tensioner using the center bolt on the tensioner puuley. You will be able to tell which way the tensioner must go when you start doing it. After the belt is off,Simply remove the denter bolt on the idler pulley and it comes right off. occasionally these have a left hand thread and I'n not positive on this model, as .Ithey don't talk much about these things in the manual, so if you can't loosen the bolt with a reasonable amount of force, try going the oposite way. Reverse this procedure for assembly.If your new to this, It wouldn't hurt to have a spare set of hands to help get the belt back on. Let me know if you have any more questions.

I have a 94 grand cherokee, the bearing went out on the upper idler pulley. my question is are these standard or reverse threads on the bolt holding the pulley on and any tips on breaking this bolt loose...

Your threads should be standard right hand. Don't worry about the pulley turning when you break the bolt loose. The bolt is isolated from the pulley by a bearing (the one that failed) so the two turn independent of one another.

Good luck.

Need to know how to adjust serpentine belt, please show diagram. 6 cyl engine.

Really don't need a diagram. Loosen the slide bolts on the power steering pump. loosen or tighten the pump by turning the jack screw (long transverse bolt) under the pump. Once the belt is tightened up, lock down the slide bolts and you are finished.

Need to replace water pump on a1997 chevy lumina 3.1L V6 need insructions

3.1L And 3.4L (VIN E) Engines
  1. Disconnect the negative battery cable.
  2. Partially drain the cooling system into a suitable container.
  3. Remove the drive belt guard.
  4. Loosen the water pump pulley bolts before removing the drive belt. This should help keep the pulley from turning as the bolts are loosened.
  5. Remove the drive belt. Please see Section 1.
  6. Remove the water pump pulley bolts and remove the pulley.
  7. Remove the water pump bolts and separate the pump from the engine front cover.
To install:

Exploded view of the water pump and front cover arrangement—3.1L and 3.4L (VIN E) engines

  1. Clean all parts well. Use care when scraping gasket material from the front cover and the pump. Do not gouge aluminum parts. Clean the bolt threads well. The torque specification is low and if the bolt threads are dirty, an accurate torque is not possible and leaks are likely to develop.
  2. Using a new gasket, install the water pump to the front cover. Install the cleaned and lightly lubricated water pump bolts. Torque to 89 inch lbs. (10 Nm).
  3. Install the water pump pulley and bolts and torque to 18 ft. lbs. (25 Nm).
  4. Install the remaining components in the reverse order of the removal process. When refilling the cooling system, use the proper mix of DEX-COOL® and water. Check for leaks.

there should be a torx socket that fits it pretty well. as far as being lefthand thread, I think that those are normal threads. usually its the idler pulleys on fords that have a lefthand thread design.
