16 valve water leak??

My brother has a 92 4 door Kick that has a water leak that I can't find. The water is dripping off of the back of the engine right where the tranny hooks up(bottom). The water pump was leaking so I changed it (thinking that may be the problem) but it's still dripping water. I know there's a little block on the back of the engine where one of the heater hoses hooks up but it appears to be dry. Also it leaks the most right after the engine is cut off. Any ideas?? Thanks.

Re: 16 valve water leak??

88.5:

When you replaced the water pump, did you notice that there was a long pipe that came out of the rear of the pump and had several water lines attached to it?

There is an "O" ring that fits on this "manifold" - for lack of a better word - and helps it seal against the back side of the water pump housing. On the 1.3 block, this "O" ring is known to fail after a while. I assume that the 1.6 block is very similar in layout in this area...

What might be happening is coolant is getting by that "O" ring and is being blown by the radiator fan onto the transmission bell housing around the starter.

Anther sign of this is a kind of crusty brown buildup on the block in this area where the aluminum is oxidizing with the water.

Check it out.

It's kind of a pain to get at, but once you have cleared out some space through a bit of diassembly in the area, the manifold slides right out and the "O" ring can be replaced.

Ack

Ack...Thanks for the idea. The 16 valve does have the same setup so I'll inspect it a little closer. I really want to figure this one out!
