What causes a Chrysler 300M engine to overheat?
Higher concentrations may result in poor cooling performance and premature water pump seal failure. This antifreeze/ coolant may not be mixed or substituted with any other type . When Engine is cold: Thermostat is closed, cooling system has no flow through the radiator.
What happens when you turn off the airconditioning on a Chrysler 300?
The engine temperature immediately begins to drop and then settles in at just below the half-way mark. This tells me the system is clean and that the coolant is flowing nicely. BUT, as soon as I turn “OFF” the airconditioning, the lower radiator hose begins to slowly cool down and the engine heats up again.
What kind of coolant is used in a 300m engine?
CAUTION: The cooling system is designed to function with a 50/50 mixture of Mopar Antifreeze/Coolant, 5 Year/10O,000 Mile Formula (MS-9769) or equivalent, and distilled water. Higher concentrations may result in poor cooling performance and premature water pump seal failure.
Why is the thermostat on my Chrysler 300 overheating?
If the hotter air from the condensor and radiator combined are hot enough they might get the coolant warm enough to open the incorrect thermostat, that makes some sense. Where did you get the thermostat?
What to do if your 300m engine overheats?
He’s worked on 300M cooling systems before. When I turn “ON” the heat and crank the fans wide open, the temp will drop BUT not near the normal operating temp. The lower radiator hose still stays cool enough to touch. When I turn “ON’ the AC, the temp drops beautifully to normal operating temp.
Why does my 300m engine get hot when I run a / C?
Also, the rad is a cross-flow design, meaning the coolant moves from side to side as it is cooled. The fact that one fan blows cooler air than the other is also normal. When you run the A/C, the condenser, which sits in front of the rad gets hot. The air passing over the condenser then passes over the rad.
