Thanks Super400! My 92 sc400 needle is in 2'oclock position. Replaced ecu sensor, temp gauge sensor, thermostat w/oem. Infrared
gun says its 205 degrees on one side of thermostat and about 190 at heater hose side. Anyone?

Have you check your coolant levels and made sure you have the correct water to antifreeze ratio? Also how old is your coolant? Have you replaced the coolant temp sensor on the top of the engine? Is you fan spinning correctly? You could also have a clog in the heater core. I know that’s a lot, Therese just a lot of variables with these things. It’s super rare but you could also have a blown head gasket.
