1999 Ford F-250 Super Duty Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1999 Ford F-250 Super Duty

The cooler for the EGR valve can leak coolant internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine.

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.

Delamination of the diesel fuel tank can occur resulting in a loss of power due to debris clogging the fuel filters. In some cases the fuel injection pump and/or fuel injectors have also been damaged. Ford has issued a service bulletin (#19728) addressing this concern.

This truck has a 6.8 L gas engine which gets about 12 MPG empty and 8 mpg when used to tow my 13,500 lb. fifth wheel trailer, but the power is worth it. It's also handy to haul stuff to the dump! The only problem I've had in 10 years is an overhaul of the air conditioner and problems with the electric door lock and light sensor on the passenger door.
