OK here goes, last year before I put my car away it had a leak which I thought was the water pump. So while I was painting my car I pulled the old one off(It was loose also)and it looked like it had been leaking! So I replaced it and guess what yup it still leaks
And the kicker is only when I drive it!WTF It's not from the WP and I don't know what else to do! No water from the exhaust, HELP!
Anybody else have trouble like this?
Oh and it's on the passenger side front of block...

Isn't there a freeze plug up front there, behind the pulleys? If not perhaps the intake manifold gasket has given up on the water jacket up front. Any water in the oil?
It probably only leaks while running cause the coolant is under pressure. Is the water coming from the front of the block or from the intake manifold by the heads? Could it be seeping under the thermo housing? More info please.

Soem other places where it could be coming from are:

Knock sensor
Temeprature sending unit
Radiator hoses loose ,Water pump seals defective, leakeage from radiator core or header tank, engine drain plugs or water jacket core plugs leaking.

So you can see puddle of coolant under the car when it is stationary?

 

No water in the oil, and no puddle under the car I've checked the radiator it's dry, I'm going to look for a pressure tester today and try that and see if I can get a better idea, It looks like it could be coming from the head gasket just behind the alt. but it's really hard to tell the exact place. The water pump and temp sending unit are dry.

I doubt that any gaskets are leaking since you don't have water in your oil. You would see obvious evidence if any connections to the block were leaking (ie CTS connection).

I suggest you take a good look at your hoses. You probably have a hairline crack in a hose which looks and works fine when the engine is cool, but fails under significant pressure. Just my .02

Thanks I'm off to the store to get a pressure tester to help me find the leak. Man I hope it's just a hose!

 

One other thing you could do is pressure test the radiator cap. That could be the problem also.

 

I found it! It's in the manifold base DAMN! Good thing I nave a long weekend to fix it and clean up the ports! POS! Thanks for all your help.
