question about timing belt installation

Recommended Posts

So I'm changing the air filter and while installing the plastic cover, one of the 7 screws falls into the engine. I look around for it and can't find it, but also does not seem to be stuck in any belts. Car drives fine. Then when getting my oil changed, they show me my belt needs replacement. Seems the screw was rubbing against it. Got the screw out and car runs fine.

So here is my question. How difficult is it to change the belt. Seems easy from the DIY directions.

If I have my mechanic replace it, what is a reasonable charge?

Assuming you don't literally mean "into the engine" where the timing chains are (actually that might not be that bad if it goes to the bottom of the sump plate - or it could be REALLY bad and destroy your engine), but on the outside of the engine under the accessory belt.

The accessory serpentine belt exterior to the car (the long rubber one), is very simple to change.

1.) Basically you remove the airbox (unplug maf, unclip wires from fasteners, loosen screw, and clamp around throttle body). Then draw a picture of how the belt routes around the pulleys

2.) Then you put a wrench on the tensioner pulley and push down, this releases tension on the belt and you can just slide it off.

3.) Install the new belt while placing tension on the tensioner pulley.

4.) Reinstall airbox according to installation procedures.

A shop would charge 1 hour labor plus the belt.

I'll try to hunt around for a DIY but here is the page from the WSM:
