Re: 91 Mustang GT 306 Running Pretty Hot!
210 is the normal temp range. on elec. cooling fans the size doesn't matter as much as it's CFM rating you cna have two fans that are the same size and one can flow twice as much air as the other.
one easy way to tell if your not flowing enough air through the rad. or if your engine coolant flow isn't enough.
start the car and let it idle tell it starts to run warm. with the cooling fans running hold the idle at 1500RPMs if this brings the temp down, then you need to look into a high flow waterpump. If reving the engine does nothing and the only way to drop the temp is to put a fan in front of the rad. or take the car for a drive, then you have a air flow problem . You need to get a better cooling fan.
another thing you can do is replace the thermostat with a 195*. what this will do is hold is hold the coolant in the rad. longer allowing it to cool more before entering the engine. (this works best if you have a air flow problem)
