engine noise from front pulley's

I have an 2000 impala ls 122k miles that just started making a "clicking" from one of the front pulley's, I originally thought it was the water pump due to leaking coolant but have come to the conclusion that the coolant is the result of the lim, also have an oil leak on the front from somewhere that I havent found yet. The clicking noise seems to be coming from the center and top of the engine and goes away after the engine has time to warm up. Any advise as to whether I should start replacing pulley's and or pumps or are there some sensors that I need to be looking at? Thanks in advance.

Be sure to check your belt for frays and alighnment first either can cause this type of clicking...

I fixed it, it was the serp. belt.:screwy:

Great! I am so thankful you re-posted with the fix...Don't be a stranger to the forum, this thread may be of help to others down the road.

Thanks...Dave~
