Default Leaking Coolant

My 97 SSE got hot yesterday (about 240). When I checked the overflow tank it was empty. The radiator was down also. After looking further I discoverd the right side of the engine on top of the transmission. It looks like the intake is leaking. I have read on this forum about the plastic intakes cracking. Is this a big job to replace? Also the car will not start now it acts like it wants to but it spits and sputters. Help

that would most likely be the TB gasket, and its an easy change

If it'* leaking onto the driver'* side of the transmission, that'* exactly where my TB leak was. A new gasket an maybe an hour and a half (inlcuding cleaning the throttle body) was all it took.

Refill coolant, drive the car until it warms up, take the engine cover off, and shine a flashlight below the throttle body. You'll see the seepage if that'* what it is.

You guys may be right. The upper intake and the gasket could be leaking. But what about the water pump? That tends to leak too. I had the same problem and got it fixed by replacing the water pump because it was leaking.

The water pump is on the opposite side of the engine and lower than his reported leak. Out of the question.
