Engine and engine cooling
Model years: 1995, 1996
Problem: Vehicle description: 1995 passenger vehicles equipped with the 2.0l and 2.5l engines, and 1996 vehicles equipped with 2.5l engines. Tightening of the engine cooling fan motor bearings, up to and including motor stall, can result in increased motor torque and higher than normal motor current and accompanying high motor temperatures.
Risk: Overheating of the cooling fan motor due to excessive current can result in smoke and odors from bearing grease, insulation and other internal motor components. If electrical current continues to be applied to the motor, internal motor components could ignite possibly igniting other engine compartment components.
Fix: Dealers will install a positive temperature coefficient device in-line with each fan motor. Ford will also extend the warranty on the engine cooling fan assembly to a total of 8 years of service or 100,000 miles from the warranty start date, whichever occurs first. If the vehicle already has more than 100,000 miles, this coverage will last until july 31, 2001.
