Grab a flash light and look around the 4 corners of the intake, i suspect thats where
it'* coming from, because it leaks when running(coolent pressure) then starts to
slow when motor off(pressure subsides)...


It'* somthing to check anyway... ....

Is it leaking coolant inside at all?????

You're losing coolant and it'* not dripping. That means it'* being ingested by the motor and burned in the cylinders.

If it'* bad enough, your exhaust will smoke white (steam) and smell sweet.

Because your coolant is outside on the ground and apparently leaking from the water pump, you probably just need a water pump. The procedure for changing the pump is described in Chilton'* 28200. You can buy one at almost any auto parts store for $15-$20, or if your local library is a good one like mine, check one out for free. The procedure is a little messy, but it is not that difficult.

[edit] Oh yeah, your car has a plastic coolant bypass elbow that can crack and leak that is in the same general area. It connects the bottom of the lower intake manifold withthe belt tensioner assembly. It would be a good idea to get a mechanic'* mirror and a flashlight and look carefully to make sure it is not your problem.

And, a bad water pump can sometimes be diagnosed by looseness of the pulley, more obvious with the belt off.

There are holes in the power steering pump pulley, you will have a bolt on the top and a bolt on the bottom... 13mm or 1/2" I forget...

Both will have to come out and the pump will have to be moved slightly

thanks the really was messing with my mind for a while, any way i replaced the water pump and so far no leaks so i guess i'm down asking questions for now in less i run into some more trouble, just a side note my buddy said he went to pep boys and asked what it woud cost to have a new water pump installed and they said it would cost roughly around $407, not including the new water pump which is a thirty dollar part.
