Cooling System Diagnosis

Another update. I installed another radiator (4 core) and still the same problem. I borrowed a laser temperature gauge from a friend and used it on several spots on the engine and it shows the engine at normal temps, about 190-195. I guess the sending unit/temp gauge is bad. I will replace it and update again soon.

Quick question, have you checked the temp flare up again after you changed the rad. It is common for the first opening of t stat to flare as air is released from right below t stat. Also prob what happened is so one did head gaskets and put heads on wrong sides. This is'nt a problem except for sender location. I would try and remove plug,yes i saw you tried already.
