I have a 2003 Chevy Express with 99K and noticed what appears to be a leak from the water pump. The water pump seems to be a doable repair for a computer geek, but should I be looking into the timing chain? That would put things out of my skill set. Please advise

i think the chains have a pretty good service life. I haven't seem any fail where i work.

yea, the chain can stay til about 300K in most instances, but replace the water pump. Normally when the chain is fatigued it is time for a rebuild anyway.
