I am looking for input on what is the cause of a new coolant leak out of the top/back of the Engine behind/near the intake manifold. I can see coolant dripping slowly down the side of the engine and across the starter. There is a heater hose that clamps onto a metal tube that appears to be fitted into the head. I can't see how the tube is fitted into the head, but I believe that this is where the coolant is coming from.

Has anyone seen a leak here before?

There appears to be no access to this coolant tube. Do I have to pull off the whole intake manifold assembly in order to get access to/fix the leak?

Should I try adding stop leak to the coolant? Might this work?

Thanks.

 

That is one of the heater hoses. There is a fitting into the head with a hex end and a sealing washer. I would first change the hose as the rubber is roughly 14 years old. Its not hard to do but some universal quarter inch sockets help alot.

 

if you ready to change the radiator and probably heater core, yes you can use stop leak. Using "stop something" stuff on the car its always bad idea.

 

Is there a walk through for replacing this hose
what is the part number?

 

On a though inspection it might be the gaskets of the main engine block coolant loop that has a history of leaking at the tubes along the left side engine block

This would be below the intake manifold

This would be different then the heater core loop
