Cooling fan only comes on with heater or a/c on.
My 2000 Acura RL normally runs beautifully. Recently, it has been
overheating. The cooling fan does not come on by itself. Only with the heater
on at full blast or with the a/c on. I was told to use the heater only, not the
a/c. But as soon as you turn the heater off, the cooling fan goes off. What
causes this? I've changed temp. sensor and something else, can't
remember. Any other suggestions?
get a thermostat from the dealer and flush the coolant , it should be done anyways the coolant gets contaminated like oil does and a quality stat will eliminate that problem , if the exhaust is whitish or there's goop under the oil fill cap then that's another story , blown head gasket , has the mileage dropped ?
