Six problems related to engine belts and pulleys have been reported for the 1996 Ford F-250. The most recently reported issues are listed below.
Idler pulley came off of the motor, causing serpentine belt, power steering, power brakes, and vacuum pump to fail.
Engine pulley was coming off the crankshaft due to sheared off bolts. Dealer notified, and repairs made at consumer's cost. The crankshaft pulley failed because it is defective.
When driving through a small snow drift, on an isolated country road, snow dislodged the serpentine belt, thus disconnecting power steering, power brakes, the cooling system and discharging the battery. Luckily a passing snow plow operator assisted us or this could have had more tragic results. We have asked Ford engineers to assist with a solution. Skid plates are not made for this vehicle nor can they apparently be manufactured because of the nature of the suspension system. While our local dealer is helping to problem solve, we continue to have no reply nor interest from Ford, who claims that any sollution would be considered an accessory or improvement rather than a repair. We feel that since this vehicle is advertised as a rugged off-road four-wheel drive vehicle that is depicted blasting through deep snow drifts on commercials, it probably shouldn't break down and strand passengers when the truck is confronted with normal winter driving conditions. Further, it shouldn't leave the passengers stranded without power,engine cooling, power steering and brakes.
Bolt that holds the power steering snapped in half. After snapping in half, vibrated out towards power steering pump pulley, causing the pulley to lock up, and breaking the power steering pump bracket. Thi s caused the main drive belt to come off, leaving consumer without brakes or steering.
Bushing on belt tensioner on 7. 3 liter diesel engine fails - known defect by Ford personell.
Serpentine belt tensioner failure due to prematurely worn bushing. Problem is well known among dealership mechanics. This part controls the tension on the single serpentine belt which operates the power steering pump (may result in loss of ability to steer upon failure), the ac compressor, the water pump (may cause vehicle to overheat upon failure) and the alternator for the vehicle's electrical system.
