Default COOLANT LEAK

I recently discovered that when I leave go somewhere and come back I leave a puddle of coolant on the ground wherever I park. So I found where the coolant was dripping from on the bottom of the car slightly favoring the passenger side, but I have absolutley no clue as to where or what is leaking when I looki in the engine area. Any thoughts on how difficult it is to replace a water pump( my dad said was possible problem) and or how to go about fixing this problen. I would like to have someone explain possible solutions and ideas to help fix this coolant leak.

It would be nice to know your year and trim level. Please put that in your signature.

In the meantime, feel the bottom of your water pump for seepage. We'll get into more detail when we figure out what you're driving.

Ok. Now we're good to go on this. Just want to make sure you get that in there now so each time you post, people know what advice to give.

Underneath your supercharger nosedrive you'll see a water fitting going into the end of the lower intake manifold. If you can't find it, your brother can help you identify it. Make sure the fitting isn't leaking. It'* plastic from the factory and should be replaced with a metal fitting as soon as possible, whether it'* leaking or not.

If there'* no coolant there, the next likely spot is the weep hole on the underside of the water pump. If that'* where it'* coming from, it'* going to **** a water pump very soon. In that case, start planning to replace it now.

These are the two most likely spots. Ultimately, you're going to have to get under there and REALLY narrow it down.

If you've never done one before, get a service manual. Even a generic one. There is also information in Techinfo.
