i put a new water pump on my 99 z71 about 4 weeks ago with no problems. drove it for about 3 weeks, all was fine and no leaks. the truck didn't move for about a week then . when i looked the next time i went to drive it i found a small puddle of antifreeze comin from the water pump "weep hole" on the ground. i have now been drivin it for a week and it seems to have stopped and coolant level is ok. need another new water pump??? this one is a lifetime warranty but just wondered if its ok since it stopped leakin. any ideas? thx

I have a '96 z71. Just changed the water pump. Before I changed the water pump, the intake manifold gasket was seaping. My mechanic told me now that I have a nice seal around the water pump, the manifold will probably start leaking and sure 'nuff. I would check that out. Be careful if u decide to change it yourself because I have heard of many ppl breaking them when they are torqued down. I think it's only about 14-16 pounds.
