need help finding source of antifreeze leak

[beatlebob32]

Just purchased this 1992 supercoupe, real excited about it but it is puking antifreeze like crazy and I can’t see from where.

Previous owner seems to think the problem was with the water pump, but I’m not sure.

No smoke and oil looks good so no reason to suspect head gasket at this time. Also head gasket has already been replaced in the car‘s life. 115k on it now.

Could use a set of more experienced eyes.

Thanks!

Put a pressure gauge on it set for 17 lbs or so and pressurize it. My leak came from the lower hose clamp being loose. Good luck

Oil can look good with a failed headgasket. Way to test is a combustion leak tester on the expansion tank.

Leaking that far over could be a freeze plug? Lower hose?

And I agree, time to pressure test.

Also check piping/hosing to oil cooler as well?
Does it leak more or only while running? It's a pretty steady stream for sure.
It should be somewhat easy to pinpoint. May be as simple as a loose clamp or cut
lower hose at clamp.

Thank you, I think it only lease when running but I will take a look. As I am fairly new to this engine compartment, where is the oil cooler?

The oil filter mount includes an 'exchanger' sandwiched between the filter, and the front cover:

From what it looks like in the video(location of antifreeze dripping off frame) I'd say either oil cooler lines or possibly the heater core hose one of them comes off the front drivers side and wraps around the back of the engine to get to the passenger side firewall
