Default Coolant Leak - 2004 Saturn L300

My wife has a 2004 Saturn L300-2, and we've noticed a coolant leak on the driver's side of the motor. The uppermost part of the motor that is wet with coolant is where the hose that's at the bottom of the reservoir tank meets the engine block. I originally thought it was the thermostat, but from googling, the thermostat only has one hose coming off of it, and this part has 3 (one going to the radiator, one to the reservoir and one to the back of the motor... the heater core?)

Any ideas on what that part is and what could be leaking? Thanks!

Note: The water pump had a slight leak as well, so we replaced that already, this other leak is more severe and on the opposite side of the motor.

REWARD EXCELLENCE!

Welcome to the show.
Best way to find a coolant leak is a pressure test. Search This board and you will find tons of info on how to do a test.

Yes! That's the part! That's where the wetness looks like it starts. I'll have to see if I can find the part numbers for the fitting and the gasket/o-ring to track those down...

Thanks!

Now that you found the problem - you might want to ask did you change the Thermostat as well? This is the other part others forget as it is buried under the intake runner. If your Saturn has not had this change this would be a fix that should be done as well. Those hoses and gasket should be readily available at your local auto repair parts store or if your not able a shop should be able to do this for you. So when was the last time the belt was changed and thermostat and hoses changed?

REWARD EXCELLENCE!
