Timing marks

All wheel drive automatic.

What are the timing belt marks?

Four cylinder four wheel drive automatic 130,000 miles.

Upon cold start there is a noise coming from behind the timing belt cover. Raising the RPM's a little it goes away. No noise with engine at operating temperature. It has done this for four years.

Check timing belt may be due for change or check water pump, timing tension-er bearing idler bearing or oil pump as well can cause problems.

Hi, I just bought this vehicle with 98,000 miles. I had some maintenance done on it (spark plugs, wires, transmission flush) and the mechanic recommended the timing belt and water pump be changed. The timing belt he said needed to be done at 90,000 miles per the car's maintenance schedule, but when I asked him if it looked worn he said they have to take the engine apart to tell.

My first question is, is there any way to tell whether this was done by the previous owner? I got no history information from the dealer when I bought the car. Also, what else should I have checked or done as long as they are doing this? The price he quoted for the belt and water pump was $477.00.

Thanks for your help.
