Four problems related to radiator have been reported for the 1998 Ford F-150. The most recently reported issues are listed below.
Blown head gaskets, drove truck in town and parked in driveway, then would not turn over next day, radiator coolant in cylinders, no warning lights came on, engine oil ok, coolant level ok. Truck was running fine then this happened.
What isn't wrong with this truck? with less than 80,000 miles on it. . . Spare tire fell off while being driven, interior lights randomly stay on, both doors are rusting out from the bottom, knob to regulate temperature fell off and assembly needed replacement, front brakes calipers stuck and caught on fire, exhaust system has rusted off twice, transmission went up and was replaced under warranty at less than 20,000 miles, radiator rusted through, and the headliner is falling down off the ceiling. I've probably missed something but can tell you that I will never own another Ford.
: the contact stated a loud pop sound was heard and a piston or rod started knocking loudly. The contact removed the radiator belt, inspected the water pump, checked the plugs, then noticed liquid coming from the exhaust including anti-freeze. A local parts store informed the contact of hydro lock problems with that engine. The service dealer and manufacturer were notified and the contact was referred to NHTSA.
Thermostat failure. Mgm.
