    leaking expansion tank

    Hi guys, just wondered if anyone has come across the expansion tank leaking @the neck where it is inserted into the tank. I noticed dry residue around the cap, while double checking to see that the cap was seated I found the entire neck spinning inside the tank with the cap. This would probably explain the spike in operating temps lately and loss of coolant.

    Yep, I had one fail that was only 2-3 years old. The new one has been working ok so far. I wasn't happy with the short lifespan though...
