Mystery coolant leak

99 Blazer 4.3 automatic tranny.

The water is not leaking from the front or top part of the engine.
I checked the water hoses that go through the top of the firewall and they are dry.

When I put water in the radiator the water is dripping out immediately down across the bell housing on the transmission.

I crawled under the car but I can not find the source of the leak.

Does anyone know what could be leaking back there?


Thanks in advance,

Tony

Probably on top on the lower intake between the intake and the valve cover and then depending on parking angle runs down. Also there is a gasket on the rear of the intake also that can leak back by the distributer. Lower intake always goes by 100k miles.

I would agree with muddog on the lower intake, but if for some reason it's not that, then you are looking at a freeze plug...

Thanks guys

I just wish this was designed so you could actually see back there.:banghead:

Well it was the intake that was leaking.

I removed the A/C compressor and found a BIG leak on the right side of the intake.

garage wanted 500 bucks to do it so I did it myself for $45 (gasket kit)


Good call and thanks again!
