Yes yes, this is serious thread resurection. I was searching for an answer on this issue once again as it was never resolved. I installed a new sensor and it is still not woking. I also checked my gauge and I know it is working. I did all the bleeding and I have actually topped of the radiator a couple of times. Not much, just a tiny bit each time. I was wondering if it could be a grounding issue from the thread sealant. Anybody ever find that an issue?
