Question about 1991 Geo Prizm

1 Answer

Timing belt broke

I have a 1991 geo prizm and have talked to a few people about replacing this belt. They all say that this is an interference engine. Its the dohc engine. I was just curious what the odds were that I didnt smash a valve? There is no knocking when I turn it over and it doesnt sound like anything is hitting. I guess my question would be. Is it worth while to do the work and put the belt on or is this engine toast for sure?

I have checked with Gates who make almost all the belts and they show your engine is free wheeling in there application guide, so just replace the belt and u are good to go, here is a link to the site

No this engine is not supposed to be an interference engine.
So you may not have damaged any pistons or valves.

I broke the belt on my prizm yesterday that controls the alternator and water pump. The engine heated.I had a new belt put on and did my delivery job that night(250 miles). Today it died on me. Could this...

If the timing belt broke the engine would sound way different when turning over and it would crank faster since you would not have compression. Look thru the oil cap while cranking. You should see the valves moving

No, it should make a difference if you replace the plugs and wires when it comes to your timing belt. It will not effect the timing belt at all.
