1999 Ford F Super Duty Engine cooling Problems

“At about 55,000 mile the engine began to randomly stop. It would start right back up. This usually happened when accelerating from a stop. After a while it began to happen more often and not restart right away. After having the truck looked at, I replaced the camshaft position sensor (cps). I am unsure if the old part is still available.”

“While driving on the highway, crossing an intersection, or idle in traffic, the diesel engine in my1999 Ford f250 dies, leaving me stranded in dangerous situations. I have replaced 2 in the last 6 mos. At my cost.”

“5.4l Ford triton engine spark plugs were changed at 84,000, at 110,128 spark plug on #7 cylinder came loose and blew out. Fuel air mixture comes out the spark plug hole which is dangerous(has been known to start engine fires). There is a design defect in the aluminum heads not having enough threads to keep the spark plug tight. This is an expensive repair that Ford is not paying for when it is a poor design with the potential of it continuing to happen again on another cylinder.”

“At low speed, spark plug blew out of engine, causing loud exhaust noise and gasoline fumes were immediately smelled inside passenger compartment. If this were to happen at high speed with engine under load when immediate engine shutdown was not safe or possible, this condition would cause large amounts gasoline/air mixture to be exposed to hot exhaust components, causing fire hazard. If this occurred when power was critical (passing or turning in front of traffic), the loss of power could also cause an accident. …”

“Blown head gasket on right head leaking oil onto right exhaust manifold fumes comming into cab creating health hazard and oil leaking onto engine and transmission housing then onto the ground also creating an enviromental hazard plus waste of precious oil supplies.”
