DIY GEN3 Timing Belt Waterpump Oil Seal Change Part 1 Toyota Nation Forum...

Water pumps on front wheel drive toyotas are typically driven with the timing belt. You will have to support the engine weight from below and remove the upper right engine mount. The external belt driven alternator and A/C pump belts are in the way and they must be loosened and belts removed to pull off the plastic timing belt access covers. Once you pull the top cover off, you will see the water pump. Be sure to set your timing right after your pump replacement. The idler pulley tensioner often does not provide enough force to maintain tension on the timing belt, so you will have to pry on it before you tighten it's bolt. If you don't, then the belt may slip and your car will not run.

Never as it does not have a timing belt but instead has a timing chain that requires no maintenance and should last the life of the engine.

Timing belt broken? Take your dist. cap off and see if it's turning.

The Toyota Celica Supra has the 5M-GE engine which is NON-interference motor. The worst a broken belt will do is leave you stranded.

Good Luck

SOunds like the timing belt has broke. To check you can take off distributor cap and turn over engine and see if the rotor turns. If not you have a busted timing belt. Please rate this a fixya if this helps.Thanks!!!
