1998 Ford F-150 Problems

An illuminated Check Engine Light could indicate that one or more of the ignition coils has failed due to excessive spark plug gap. To fix this problem, the ignition coils that have failed, the spark plugs, and all coil boots should be replaced.

An oil leak may develop from the the right side head gasket.  Oil from this type of leak will commonly drip onto the starter. Our technician tell us an updated head gasket is available to correct this concern.

There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.

1998 Ford F-150 Recalls

Vehicles sold or currently registered in states using corrosive chemicals to de-ice the roads may have fuel tank straps that can rust prematurely and fail. If the fuel tank were to shift as a result of a broken strap, the fuel lines could separate or the fuel tank could contact the ground. In either case, a fuel leak could develop, increasing the risk of a fire. Dealers will replace the fuel tank straps with straps that have increased corrosion protection. Early in the campaign, if replacement straps are not available, dealers may install a cable support under the strap as an interim repair or a steel reinforcement over the existing strap as a permanent repair. This recall is expected to begin September 12, 2011. The Ford recall number is 11S21.


Ford has recalled 1998-2000 vehicles equipped with compressed natural gas fuel systems due to an incomplete label for the fuel tank. Ford sent a new label to owners.

The truck now has 170k miles and starts every morning. No le...

This truck has been overall the best truck I ever owned. I purchased it in early 2000 when it came off a 2 yr lease from a dealer with 32,000 miles. Up to 84,000 miles I had no significant issues other than standard maintenance. Then, one day coming home from work, the fan pulley assembly simply "Snapped" off the crank. I had to replace the engine with a Ford rebuild for $4,700.00 in late 200...
