99 Camry 4cyl, noisy engine after water pump failure

You wouldn't think the engine overheated,..as the pump siezing would shut the engine down by shredding the cam-belt.

As an aside, was the engine needing lots of coolant top-ups prior to this?

Is this noise metallic or a deep thumping sound to it? Thinking bearing probs there or does the engine shake? Maybe the balance shafts are out of sync due incorrect belt installation.

Maybe the bolt on the timing belt tensioner was left loose. I've done that once or twice myself and realized it only after starting it up and it sounding like there was a leaf blower under the hood. Take it back to the shop that did it, it's not terribly hard to check.

Nope, no overheating, and it never needed more coolant.

It's pretty hard to describe the sound, it's as if the car is working hard. A low growly sound. As soon as the engine's gets past around

Wow, I had this problem after a timing belt change although the belt wasn't bad beforehand. I also have a 99 Camry. I brought it to three shops (including the one who originally did the work) and they all said the belt was installed properly. Prior to belt installation, the engine was so quiet I could almost not even tell it was on. Now it's noisy, just like the original poster mentioned.

This was about 1.5 years ago; I've just been living with it but I am not completely happy!

I'll be interested to hear any other posts. I haven't been able to get anyone to check any bearings because they all say that would require a lot of work. I haven't thought about the bolt; but the noise isn't quite that loud (plus I would hope that one of the other shops would have noticed that).

It sounds like the timing belt has stretched. On my '98 V6, the timing belt had stretched and made an AWFUL bearing-like grinding noise.

My suggestion is to get the timing belt, idlers and tensioner replaced. It's NOT going to be cheap, but it's likely one of those three has gone bad...
