Broke timing belt ,reset timing - 1990 Toyota Camry

Markings are usually on the Cam and Crank Sprokets. Not sure what car you are asking about but Most cars have interference engines which means If the Belt broke and wasn't being changed during regular maintenance then you probably bent some Valves in the Head. You have an expensive problem now

If the car started and ran fine before the serpentine belt broke - that may be the answer to your problem.

If the belt also controls the valve timing (not the ignition timing, which is a different thing) the valve timing has probably altered. You will have to reset the valve timing using the timing marks for your vehicle.

In a worst case scenario, a snapped timing belt can allow the pistons to hit the valves and damage them. If this is the case your engine isn't going to fire up.

If you're not sure what to look for or do - give a mobile mechanic a call

When you break a timing belt, you get a kit with a new
water pump,pulley's,tensioners & belt

Also you get an instruction manual to follow for
the timing of the cams & such

If you only bought a belt, you should also have instructions

Nothing-- then you go to the internet & find a picture & also
can watch You Tube Video

If the belt broke-- what about bent valves,BEFORE,before
you address the belt replacement

Good time to do a cylinder leak down test

The Dodge Neon has an Interference engine. That means when the timing belt breaks, you likely have bent some valves. You will need to remove the head, and have the valves replaced. Best done by a qualified mechanic that knows how to replace the timing belt.

I had a 1992 for years and never set the timing unless it's set by the computer module.

Its always hard to know if you bent valves or not with out taking it to a garage. Ask yourself these questions. When the belt broke did you continue to try and drive it? Did you try and run the vehicle after the belt broke and how how was vehicle did the temp spike up and stay hot for long?

If you answered no then chances are your probally just fine with a new belt and reset the timing

The timing belt can be fixed, engine is not junk because of that.

That will depend on why it stopped. If the engine seized because it overheated then your are going to have to do more than replace that timing belt. If it just shut down but still starts now that it is cooled down then no unless you timing belt broke. If it cranks but doesn't start now you have damaged something else in the engine when it over heated. Yo can do a compression check to see if your timing belt is broken.

You can go to your local AutoZone store and they can read and erase the code for you with a OBD II scanner for free.

Best thing to do is get a service manual, a Haynes manual has sufficient information for most service, including timing belt. Unfortunately, there is a good chance you have some bent valves because when the timing belt breaks, the pistons can hit the valves.
