1995 Ford Mustang

Engine Cooling problem
1995 Ford Mustang V12 Two Wheel Drive Automatic 133000 miles

The electric fan stopped running and the car overheats when not in fwd motion. I replaced the fan.
The new one ran but then shut off. I measured the voltage across the pulg and got 8vdc. I shut the car off and started it again later the fan came on and the dc voltage across the plug to the fan was 12-14vdc. What will make the voltage across the plug to the fan drop to 8vdc?

pls email ans to

Hello -

To better assist you is your model just the mustang or the cobra, or cobra R or GT and also what is the engine size in liter.

Is the car overheating now that you changed the fan motor?

Turn all the AC controls off. Start the car when the engine is cool and see if the radiator fan is turning. It should not be. Turn the AC on. Is the radiator fan turning now. It is supposed to.

When you were doing your checks was the AC on

The 95 mustang is a v6 3.8 LTR.
Why will the cooling fan only run when the ac is on what about the voltage drop. Pls explain

Hello -

I have attached what the manual states. Basically if the fan doesn't need to be on. It isn't.

Electric cooling fan system consists of a fan and electric motor attached to the fan shroud. Engine temperature is monitored by the Engine Coolant Temperature (ECT) sensor. Fan is controlled by Constant Control Relay Module (CCRM) with inputs from Powertrain Control Module (PCM). The electric cooling fan is wired to operate only when ignition switch is in ON position and engine temperature exceeds specified temperature, or when A/C is on and vehicle speed is less than 48 MPH.

Hope this helps

Hello - that I have the rest of the info on your car.....there is a recall on the cooling fan...interesting. I have all of the recalls below. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.

I printed out the one on the cooling fan for you to look at...

Mfg. Campaign No: 01S30
Number of Affected Vehicles: 00069526
Beginning Date of Manufacture: 1994 04 13
Ending Date of Manufacture: 1995 08 11
Vehicle description: Taurus/Sable vehicles equipped with 3.0L and 3.8L engines and mustang vehicles with 3.8L and 5.0L engines. It is possible for the engine cooling fan bearing to seize.
Should this occur, excessive heat could be generated which could melt the fan motor electrical connector. Components inside the cooling fan motor could ignite potentially resulting in an underhood fire.
Dealers will inspect the engine cooling fan assembly and install a circuit breaker. If the cooling fan is inoperative, the fan and motor assembly will be replaced. Owner notification began December 28, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact ford at 1-866-436-7332.
