Re: {Chrysler 300} 413 with a/c thermostat

Speaking of water pumps/impellers, If a non-A/C 300G comes standard with a fan clutch normally reserved for A/C cars, does it also use the water pump that would normally be on an A/C car? It doesn't use an A/C radiator, shroud, or thermostat housing like an A/C car would have, only the clutch, which I presume is more for reduced fan noise at the higher rpm a G motor could be expected to operate at while driving at high speeds during the flying mile at Daytona? ;-)

Thermostats do not control the top temperature, they merely begin to open at the listed temp. A stuck thermostat can cause overheating, it would happen rather quick too. I would think a 180 degree stat is appropriate for our cars but I'll leave that to critique by those older and wiser.

Overheating at idle and low speeds is usually an air flow matter related to fan shroud placement, radiator support seal, fan blades properly distanced from core, or fan clutch.

Overheating at high speeds is usually water flow issues, collapsed hose, plugged radiator or rusted away pump impeller.

Hey All,
My second car has 413 with a/c

It has a 195 thermostat and runs up to 250*

Should I install a 160?

Dave
