2004 Ford F-150 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2004 Ford F-150

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.

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.

Intermittent rough idle may be caused by the EGR sensor sticking, causing the EGR valve to stay slightly open. The valve and sensor must be replaced together to correct this concern.

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.

The clock spring jumper wire behind the driver's air bag may come into contact with the lower horn plate, resulting in damage to the wiring. If this occurs, the air bag warning light may illuminate or the driver's air bag could deploy unexpectedly, increasing the risk of injury or a loss of vehicle control. Dealers will replace the jumper wire with a new design, which includes a protective mesh cover. This recall is expected to begin on February 28, 2011.

Ford has recalled certain 2004 F150 trucks for a concern with the manufacturing of the fuel tank. Fuel may permeate the liner of the tank, causing an odor, a leak, or a Check Engine Light. Leaking fuel and vapors are flammable and hazardous. Dealers will replace affected fuel tanks.

I absolutely hate this truck, first ford i have owned (all others being Chevrolets) and i have had nothing but bad luck and mechanical failure nightmares with this piece.

The Interior is the cheapest yet, i am a builder and most of my t...

This has been a very comfortable and quiet vehicle. It does eat brakes & rotors fast but it is very heavy and well built so worth it over the long haul.
