TIMING BELT AND TENSIONER SYSTEM

Replacing the timing belt is within the capabilities of a competent "DIY" (do it yourself) owner, but access to the shop manuals and some special tools are required. Typical shop cost for timing belt and water pump replacement runs from $500 (all amounts in US dollars) to $1000, while the DIY cost should run from $250 to $300.

This article merely gives some helpful information not found in the manuals, and does not by itself furnish sufficient information to perform the replacement operation.
We recommend that you do not try to replace the timing belt without the manuals and special tool There are many things that you should check while you are in there ("WYAIT").

This is a good time to inspect and, as needed, replace the accessory drive belts. On the four-cam engines, take a very careful look at the distributor caps and rotors. Especially if you are paying a shop to replace the timing belt, give very serious consideration to replacing the water pump at the same time.

The extra labor charge should be minor, since removing the belt fully exposes the water pump, while replacing the water pump alone requires removal and reinstallation of the timing belt.
The pump should be about $125 or so from an independent vendor, although a shop will usually charge more.
This small investment could help you avoid a flatbed charge and an expensive repair bill later.
