I'm kind of confused here about the expansion tank on my car. I just drove it an hour home (50 degrees out, interstate ride home) and I got home, checked all my fluids like I do from time to time. I opened the expansion tank cap, and the coolant in the tank is COLD.
Does the fluid not circulate through the cooling system to and from that expansion tank? I have aeroforce gauges and it never got above 180* temps, it hovered between 172-180*. I have the on 3 t-stat relocation to the top of the radiator, a 3 core fluidyne radiator, and the car is running great. Not down on power or anything.
The radiator and t-stat housing are hot to the touch. I squeezed the lower radiator hose, and the upper radiator hoses, and the coolant moves around in the expansion tank.
I'm not understanding this.
