The 2004 Excursion is Ford's largest SUV built on Super Duty truck bones. Engine choice defines your ownership experience: the 6.0L Power Stroke diesel is notorious for catastrophic failures, while gas V8/V10 variants are relatively trouble-free but thirsty.
6.0L Power Stroke EGR Cooler Failure Leading to Catastrophic Engine Damage
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: White smoke from exhaust indicating coolant in combustion chambers, Rapid coolant loss with no visible external leaks, Overheating followed by rough running or no-start, Milky oil or oil in coolant indicating head gasket or worse
Fix: EGR cooler cracks internally, dumps coolant into cylinders, hydrolocks engine and destroys pistons/rods/bearings. Requires complete engine rebuild or replacement. 40-60 hours labor for full rebuild with all updated parts (head studs, EGR delete, oil cooler upgrade). Many owners opt for reman long-block swap at 25-35 hours.
Estimated cost: $8,000-15,000
6.0L Power Stroke Oil Cooler Failure and FICM Issues
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Hard starting or extended cranking especially when cold, Loss of power under load or won't exceed 2000 RPM, Oil in coolant or coolant in oil from cooler rupture, Check engine light with fuel injection codes
Fix: Oil cooler sandwich plate o-rings fail causing cross-contamination; requires oil cooler replacement at 8-10 hours. FICM (fuel injection control module) fails from heat/vibration causing no-start or severe drivability issues, 2-3 hours to replace. Often both done together as preventive.
Estimated cost: $2,500-4,000
6.0L Power Stroke Injector Stiction and Failure
Common · medium severity
Typical onset: 100,000-180,000 mi
Symptoms: Hard cold starts with white smoke and rough idle for first few minutes, Surging at steady cruise or lumpy acceleration, Fuel in crankcase oil causing dilution, Check engine light with contribution/balance codes
Fix: HEUI injectors stick from fuel contamination or internal seal wear. Replacement requires valve cover removal and special tools. 1.5 hours per injector, but typically do all eight at 12-14 hours plus stand pipes/dummy plugs. Many replace with updated/reman units.
Estimated cost: $4,000-6,500
Transmission Oil Cooler Line Failure (All Engines)
Common · medium severity
Typical onset: 70,000-130,000 mi
Symptoms: Transmission fluid puddle under vehicle near radiator, Burnt transmission smell or slipping after fluid loss, Pink fluid mixing in coolant if internal cooler fails, Sudden loss of all gears if catastrophic leak
Fix: Steel lines rust through at frame brackets or quick-connect fittings fail. External lines are 2-3 hours to replace. Internal radiator cooler failure (less common) contaminates coolant and transmission, requires radiator replacement and full trans flush/filter, 6-8 hours total.
Estimated cost: $400-1,200
5.4L Triton Spark Plug Ejection and Thread Damage
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Sudden loud popping noise from engine bay followed by rough running, Misfires on single cylinder with P030X codes, Spark plug blown completely out of head, Loss of compression on affected cylinder
Fix: Two-piece spark plugs break on removal or aluminum head threads strip/eject plug under combustion pressure. Requires Heli-Coil or TimeSert thread repair at 3-4 hours per hole, or head removal for severe damage at 12-16 hours. Preventive: never exceed 27 ft-lb on plugs, replace every 60k.
Estimated cost: $500-2,500
Front Hub Bearing Failure (All Models)
Common · medium severity
Typical onset: 80,000-150,000 mi
Symptoms: Growling or humming noise that increases with speed, Noise changes with steering input left/right, Wheel play detectable when jacked up, ABS light may illuminate from damaged tone ring
Fix: Super Duty unit bearings fail from weight and road salt. Front requires hub assembly replacement at 2-3 hours per side. Often do both sides simultaneously since failure spreads stress. Rear bearings less common but same symptoms.
Estimated cost: $600-1,000
Ball Joints and Tie Rod Ends (Heavy Duty Use)
Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Clunking over bumps especially when turning, Wandering steering or poor return to center, Visible grease boot tears or play in joints, Tire wear on inside or outside edges
Fix: 8,500+ lb curb weight accelerates wear. Lower ball joints fail first, upper follows. Full front end typically needs both uppers, both lowers, and tie rod ends at 8-12 hours labor. Alignment mandatory after. Towing/off-road doubles wear rate.
Estimated cost: $1,500-2,500
Owner tips
If buying a 6.0L diesel, verify full service history of EGR delete, head studs, oil cooler upgrade, or walk away—unmodified examples are ticking time bombs
Gas engines are far more reliable: 6.8L V10 is bulletproof but gets 8-10 MPG; 5.4L V8 is adequate for unloaded use and slightly better fuel economy
Budget $200/month for fuel regardless of engine choice—this truck is not economical
Inspect frame and body mounts carefully in rust belt states; hidden rot is common given vehicle age
Transmission (4R100 or TorqShift) is generally stout if fluid changed every 50k miles
Buy a gas V10 or 5.4L example with clean history under $15k, or avoid entirely if you found a 6.0L diesel without bulletproofing receipts—that engine will bankrupt you.

Every control module on the 2000-2005 Ford Excursion — where it lives, replacement time, and what it takes to program a replacement. Modules marked dealer / factory tool won't work after a part swap alone — budget for programming.
📍 4R100 transmission: integrated into valve body inside transmission; TorqShift 5R110W (2003-2005 diesel): external on driver side of transmission case
🔧 Ford NGS/IDS + Service Function Card
⚠️ 4R100 requires transmission pan removal; TorqShift external module is easier access but still requires VIN programming and adaptive relearn
Transfer Case Control Module (TCCM)1.8 hr R&Rrelearn only +0.3 hr4WD models with electronic shift▸ programming details
📍 attached to transfer case on driver side
🔧 scan tool for shift relearn
⚠️ Controls electronic shift motor; requires shift pattern relearn after replacement; 2WD models have no transfer case
📍 integrated within PCM and GEM/SJB; no standalone module
🔧 Ford NGS/IDS
⚠️ Key programming requires both PCM and GEM/SJB communication; minimum two programmed keys required for self-programming additional keys
