I noticed that the coolant level was low and that the coolant was accumulating underneath the intake manifold just behind the thermostat housing. I used a pump to remove the coolant underneath intake manifold about 24fl oz. I could see the coolant rise just behind thermostat housing when i added more coolant.

Has anyone had a similar experience? and what are some of the suggestions of what it could be? thanks

Car has 94,000 miles and coolant flushed every 20,000 miles.

Just take your car to the dealership and they will be able to fix the problem.

I finally had some free time today to fix the leak under the intake manifold. It turned out to be an o ring that had deteriorated. The o ring from the heater pipe that connects to the cylinder block just behind that water pump. I had to take off the intake manifold, fuel injectors, and a bunch of hoses. It wasn't a hard project i just followed the instructions on the manual that i download from this website.

Don't forget to check underneath the intake manifold for leaks of your m's.

Here is a picture of the intake manifold removed



Here is another picture of the heater pipe where the o ring went bad

surprised more folks haven't had this problem..Or maybe they have?

Going to tackle this myself soon.
