1990 Ford F-350 Problems

Catalytic converters can go bad and potentially plug the exhaust, hurting engine efficiency and performance.

Failure to change the power steering fluid can cause the fluid to become gray with metal particles. The contaminated fluid can damage the power steering pump resulting in a growling noise when the wheel is turned; the damaged pump will require replacement to eliminate the noise.. Life of the power steering gearbox and pump will be shortened if the fluid is not serviced regularly.

The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.

1990 Ford F-350 Recalls

Ford has extended the warranty coverage of the fuel pump and sending unit assembly in 1990-1993 F150, F250, and F350 trucks. In some trucks, the check valve may become damaged inside the fuel pump unit. This can cause fuel to travel from one tank to the other, creating an overflow condition. In the presence of an ignition source, a fuel leak may result in a fire. Dealers will repair the fuel pump and sending unit for up to 12 years or 150,000 miles from the original warranty start date.

THE IGNITION SWITCH COULD EXPERIENCE AN INTERNAL SHORT CIRCUIT.THE STEEL FUEL RETURN TUBES THAT CONNECT THE FRAME FUEL RETURN LINES WITH THE ENGINE FUEL RAIL CAN CONTACT THE PINCH WELD FLANGE CONNECTING THE DASH PANEL TO THE FLOOR PAN. CONTINUED CONTACT LEADS TO ABRASION OF THE STEEL FUEL RETURN TUBE AND EVENTUALLY RESULTS IN A FUEL LEAK.
