I noticed today that when I start up, I'm leaking coolant at a fair rate on the front passenger side of the motor. I can't seem to locate the exact location, but when the engine warms up, the leak stops. The leak also stops if I shut the motor off. What all is on that side of the motor that would give that kind of leak? I don't think its the water pump, but something lower. I just can't seem to locate the spot. Any ideas where i Should look? Thanks guys.

 

Most likely spot is the water pump. The T-stat housing is there and the bypass hose, the heater hose connections, lower rad hose, and block heater is in there. The best way to locate the leak is to get a rad pressure tester and pressurize it.

 

if its a auto trans the heat exchanger hose?

 

if its coming out of the t-stat housing the t-stat gasket might be wasted... its not that difficult to get in there to check...

 

I hosed everything down with parts cleaner, got it good and dry, and the next time it leaked, the t-stat and pump were still dry. I think it's comeing from the right front of block, just above the oil pan, but can't locate the source. Guess I'll have to find a tester ang crawl under with the goggles on. Thanks guys.

 

Is it leaking from the gasket for the oil cooler??

 

I pressurized the system today and found the leak in the pump shaft. easy fix. Thanks for all the input, it gave me places to look. Pictures of the old beast soon..
