Default timing belt issues/noises

Recently I noticed a rattling sound that seemed to be coming from the
a/c compressor which I thought might be a bearing getting
ready to fail. A mechanic thought it was the a/c compressor. Engine
performance did not seem to be affected, although my gas mileage seemed
to be 2 or 3 mpg less than normal.

Recently, I cranked the engine which ran about ten seconds and died.
Iturned the ignition and let the engine turn over a few times, enough
to know it won't start. The engine turned faster than normal,
indicating the timing belt failed.

I bought the car in May 05 with approx 88k miles on it and maintenance
records from 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 beltwas about to give out.

The 2.2 liter engine is non interference. The noise I heard was
probably a tension pulley bearing. Would the tension pulley failure
likely have occured at once, or more gradually, possibly causing engine
damage?

It's going to the shop in a few days, but I wanted to discuss the issue
with my mechanic, armed with some additional knowledge.

Usually the ball bearings are producine scate board on rough pavement
like noise before failing. Sometimes the mechanics are using cheap
waterpumps such as JMB (the shops getting them at $20) and their
bearings could fail are just after 30kMi of service.

Non interference you should be fine. Just make sure to check the water pump
for play maybe even replace it again for insurance & replace the idler

========================
That's a good point. Unless you're at the Toyota dealer, you would have
to sprecifically insist on Toyota parts to get them.
