99 Camry 2.2 liter timing belt issues/noises

Over the past few weeks I had noticed a rattling sound that seemed to be coming from the area of the a/c compressor which I thought might be a bearing getting ready to fail. It seemed to be most noticeable at startup. I couldn't or didn't hear it when I drove the vehicle. I stopped at a garage and the mechanic also thought it was the a/c compressor and didn't think it would hurt to drive the car. Engine performance did not seem to be affected in anyway. Yesterday, I got in the Camry, cranked it, then it ran for about ten seconds and died. I turned the ignition and let the engine turn over a few times, enough to know it won't start. I bought the car in May 05 with approx 88k miles on it and maintenance records ffrom the previous owner indicated the timing belt and water pump had been changed at 66k miles. The car now has 105k miles on it, another reason I didn't believe the timing belt was about to give out. Since yesterday, I have been trying to educate myself and have learned that my 2.2 liter four cylinder engine is non-interference, reducing the likelihood of serious engine damage. However, I'm now most concerned about the rattling I heard before the timing belt failure and what was causing the rattling. Isn't the belt itself a metal/rubber composition and could the noise have been the metal separating from the rubber and could that have damaged the engine? Before I sink money into a black hole, I wanted to determine whether a mechanic can detect any engine damage before replacing the timing belt? My brother in law says usually they install a belt. Then if the engine runs, you're ok. If not, you got big problems. Can anyone shed some light on my situation. Thanks.

If the belt is broken or stripped, all that can be done is put a new belt on, then BEFORE attempting to start, rotate the engine by hand with the plugs out to check for anything unusual. If it looks OK, start the engine.

The rattling was probably a tensioner bearing giving up. When it did the belt stopped running true and self destructed. Belts dont usually fray and split like alternator belts.

I am not a mechanic!

As I understand it the tensioner is the device that tensions the timing belt. It should be part of the process of replacing the timing belt.

The advice posted so far from everyone is good. When you were cranking the engine, did it turn over unusually fast? If so, that is an indication that the timing belt is broken.

Ray,

yes, the engine did turn over unusually fast. I'm virtually certain the timing belt is broken. Just got to line up the repair now. The responses to my post are very helpful and very much appreciated.

On most cars, the bearing supports a spring-loaded pulley that presses against the belt, providing proper tension.

Yes. Yes.

Usually, but it should certainly be inspected when the belt is replaced or examined, and replaced if at all suspect.

Otherwise, it will fail at 1:00AM on a deserted stretch of Route 13 in Maryland, and your phone battery will be dead. Trust me on this one.
