Losing coolant

jerrybennett

I'm losing coolant from the intake side of my engine. I'm afraid that's it's the head gasket that was just replaced 7000 miles ago. Does anybody know if there is a coolant line running up under the intake that I can't see?

If you replace the head gasket, did you go back after 500 miles or ten heat cycles and retorque the head bolts?
That is what the workshop manual says to do.

If it is a B2600i (G6) engine then yes, there is a small coolant hose that connects at the intake mounting flange and it runs up to the throttle body. Coolant runs through the throttle body. Here is a pic showing where that coolant hose connects at the intake to cylinder head flange.
