On the 1997-2003 Ford F-150, the aluminum cylinder heads on Triton V8 engines have only 4 threads for spark plugs instead of the standard 8-10. This can cause spark plugs to blow out of the head, damaging threads. Helicoil repair kits are available.

This issue also affects: Ford Expedition, Ford Explorer, Ford Mustang

Common Symptoms

Loud popping noise from engine
Sudden loss of power
Engine misfire on one cylinder
Spark plug ejected from engine

How to Fix

If not yet blown out: Use anti-seize compound on spark plug threads, torque to spec (11-15 ft-lbs), and change plugs every 30k miles. If blown out: Install a Helicoil or Time-Sert thread repair kit ($50-150 DIY, $150-500 at shop). Preventive repair kits are also available to reinforce threads before failure.

On the 1997-2002 Ford F-150, ford recalled 1994-2002 F-150s under NHTSA campaign 05V388 (September 2005) — eventually expanded to roughly 14 million vehicles across multiple campaigns — for a defective cruise control deactivation switch screwed into the brake master cylinder. The internal seal fails, brake fluid leaks into the electrical side of the switch, and the contamination creates a short that can ignite a fire while the vehicle is parked and off. Numerous F-150 fires (many in garages, some involving structure fires) were tied to this switch. The switch is always powered, so the fire risk exists with the key out of the ignition.

Common Symptoms

Cruise control intermittently stops working
ABS warning light illuminated
Difficulty shifting out of Park
Low brake fluid with no visible leak at calipers/lines
Brake fluid weeping from cruise control switch on master cylinder
Burning plastic smell from under the hood
Vehicle fire while parked

How to Fix

Verify the truck has had recall 05V388 (and follow-up campaigns) completed via NHTSA VIN lookup. The Ford remedy was a fused jumper-harness installed between the switch and the cruise control wiring; in some cases the switch itself is replaced. If the recall work is not on record, do not park the truck inside a garage and have the recall performed at any Ford dealer free of charge. As an immediate interim measure, disconnect the cruise control deactivation switch connector at the master cylinder until the recall is completed.

Typical repair cost:$0 - $0
