So my 50 is out and yes its 100 but she shouldnt be pegging to H. She'll cool down when driving but sitting at a light is dicey. Does anyone have the best source for em. Sure there easy to find but want the best vendor who paints them too with the right color.
If you're pegging the gauge, I would call it a flow problem. As in water jacket and radiator. What are the temps when you hit the radiator with an IR thermometer? Inlet to the engine and then at the thermostat housing?
Dont have a temp gage just going off the cars gage. Its 3/4s up and when I drive itll go back to half way. 59 did the same thing when the water pump started to fail. Not losing any coolant either so that can be ruled out.
