On the 2011-2019 Ford F-250 Super Duty 6.7L Power Stroke Diesel, the EGR (Exhaust Gas Recirculation) cooler on 2011-2019 6.7L Power Stroke diesel engines is prone to clogging with soot and eventually failing, particularly on trucks used for highway driving, light loads, or trucks that idle extensively. The EGR cooler recirculates cooled exhaust gas back into the intake to reduce NOx emissions. Over time, soot accumulates in the cooler's internal passages until coolant flow is restricted, causing the cooler to overheat and fail. When it fails, exhaust gases enter the coolant system, causing overheating and "puking" coolant from the degas bottle. The 2011-2014 models are particularly susceptible due to narrow internal coolant passages. Ford issued TSBs for 2011-2014 trucks covering EGR cooler cleaning/replacement under extended warranty up to 120,000 miles. The EGR cooler for 2011-2016 is OEM part BC3Z-9V425-A; 2017+ is HC3Z-9V425.

This issue also affects: Ford Bronco, Ford Bronco Sport, Ford E-Series

Common Symptoms

  • Coolant loss with no visible external leak
  • Coolant reservoir overflows or "pukes" coolant
  • White smoke from exhaust (coolant in combustion)
  • Engine overheating warning
  • DTC codes P0401 (Insufficient EGR Flow) or P2457 (EGR Cooler Performance)
  • Bubbling or foaming in coolant degas bottle
  • Loss of power under load (especially towing)
  • White deposits around degas bottle cap

How to Fix

Replace EGR cooler (BC3Z-9V425-A for 2011-2016; HC3Z-9V425 for 2017+). Check if truck qualifies for Ford extended service coverage with active DTC P0401 (Insufficient EGR Flow) or P2457 (EGR Cooler Performance). Some 2011-2014 trucks covered to 120,000 miles. Preventive: use a fuel additive (Diesel Kleen, Hot Shots Secret EDT) to reduce soot. Perform regular EGR cleaning at 60,000-mile intervals. Upgrade kits from Sinister Diesel and Dorman (904-405 kit) include both EGR cooler and gaskets.

Typical repair cost:$800 - $3,500

On the 2015-2022 Ford F-250 Super Duty 6.7L Power Stroke Diesel, the Selective Catalytic Reduction (SCR) system on 2015-2022 6.7L Power Stroke trucks - which uses Diesel Exhaust Fluid (DEF) to reduce NOx emissions - is prone to failure, most commonly triggering DTC codes P207F (Reductant Quality Performance) and P20EE (SCR NOx Catalyst Efficiency Below Threshold). Causes include degraded or crystallized DEF fluid (DEF has a shelf life of 1-2 years and degrades faster in heat), a failed DEF injector, SCR catalyst failure, DEF quality sensor failure, or NOx sensor failure. In limp mode, the truck's performance is severely limited. The system is complex and diagnosis requires a professional scan tool. The DEF injector is a particularly common failure point on 2017+ trucks.

This issue also affects: Ford Transit

Common Symptoms

  • Check engine light with P207F (Reductant Quality Performance) code
  • Check engine light with P20EE (SCR NOx Catalyst Efficiency Below Threshold)
  • Reduced engine power / limp mode
  • DEF gauge or warning light showing issue
  • Truck will not restart after excessive limp mode cycles
  • Rough running at idle
  • Increased fuel consumption

How to Fix

Diagnose with Ford IDS or quality OBDII scanner capable of reading all PCM codes. Common fixes: (1) Drain and refill DEF tank with fresh fluid (AutoZone DEF, Ford Motorcraft DEF VC-10-B) - $15-$30. (2) Replace DEF quality sensor ($150-$300). (3) Replace DEF injector ($300-$600 + labor). (4) SCR catalyst replacement ($2,000-$4,000). Always use fresh, quality-brand DEF (avoid bargain/store-brand DEF). Do not let DEF tank run to empty repeatedly.

Typical repair cost:$3,000 - $4,500

On the 2011-2022 Ford F-250 Super Duty, the 6.7L Powerstroke diesel engine exhaust manifold studs are prone to breaking due to thermal cycling. The extreme heat cycles of the diesel exhaust cause the studs to fatigue and snap, creating an exhaust leak at the manifold-to-head junction. This produces a ticking noise on cold starts that may diminish when warm, exhaust smell in the cabin, and can trigger check engine lights for exhaust leaks. The driver side manifold is more commonly affected.

This issue also affects: Ford Escape, Ford Explorer, Ford F-150

Common Symptoms

  • Ticking noise on cold start from engine
  • Exhaust smell in cab, especially with windows open
  • Check engine light with exhaust leak codes
  • Visible soot at manifold-to-head junction
  • Noise diminishes as engine warms up

How to Fix

Replace the broken exhaust manifold studs. Stud extraction can be challenging if broken flush — a skilled diesel shop can often drill and extract without removing the head ($500-1,200). If multiple studs are broken, manifold removal and replacement with upgraded ARP studs is recommended ($800-2,000). Upgraded ARP stainless steel studs ($50-80 for a set) are significantly stronger than the factory studs and resist thermal fatigue.

Typical repair cost:$500 - $2,000

On the 1999-2025 Ford F-250 Super Duty, the factory steering damper on the F-250 Super Duty wears out and fails, leading to increased steering shimmy, vibration at highway speeds, and reduced ability to dampen road imperfections. The single factory damper is often inadequate for the weight and solid front axle of the Super Duty. A worn damper does not cause death wobble directly but removes the last line of defense against oscillation. Most factory dampers are worn out by 50,000-80,000 miles.

Common Symptoms

  • Shimmy or vibration at highway speeds
  • Steering feels loose over bumps
  • Front end wanders on rough roads
  • Visible oil leaking from damper
  • Increased effort to keep truck centered in lane

How to Fix

Replace the steering damper with a heavy-duty aftermarket unit. Fox 2.0 ($150-250), Bilstein 5100 ($100-150), or Rancho RS9000XL ($100-150) are popular upgrades. Some owners install dual steering damper kits ($200-400) for additional stability. Installation is a simple bolt-on job taking 30-60 minutes. Replace the damper every 50,000-60,000 miles as preventive maintenance.

Typical repair cost:$100 - $400
