Default 99 Camry 4cyl, noisy engine after water pump failure

Maybe somebody in this group can help me out, here's my situation:

My water pump seized up causing the timing belt to be shredded. Both
the water pump and timing belt were replaced, but as soon as I left
the repair shop I noticed that the engine was louder. Right around
2000 RPM the engine has a low bogged down sound to it.

I brought the car to another mechanic and he verified that the new
timing belt was installed correctly.

Does anybody have any ideas what a water pump failure, water pump and
timing belt replacement could do to cause this? The car ran perfectly
well before the failure.

Thanks in advance,
Dan

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
2000 rpm the noise fades away.

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...
