I searched the tech blogs but didn't find a post that was similar to the situation I am having. I have a 06 LS V8 with 130k miles, I had over heating issues and read the blogs and replaced the degas bottle. Then the thermostat housing was replaced. I ran the car and it isn't overheating but I am losing coolant. I bled the system, replaced the coolant and drove approx. 3 miles and came back into my drive way and opened the hood. Coolant was coming from the overflow tube on the expansion tank. can anyone tell me what would cause this? I appreciate any help with this frustrating issue.
