Engineered specifically for late 2004 through 2007 Ford F-250, F-350, F-450, F-550 Super Duty and Excursion trucks equipped with the 6.0L Powerstroke diesel engine (utilizing the square-style EGR cooler built after 9/22/2003), the BD Diesel Heavy-Duty Replacement EGR Cooler (1090202) provides a robust upgrade over failure-prone factory units. Factory OEM coolers frequently fail at weak brazed joints under thermal stress, allowing coolant to leak directly into the intake manifold. This internal leakage causes white exhaust smoke, coolant loss, and severe engine hydrolock that can destroy head gaskets and cylinder heads.

BD Diesel addresses this vulnerability by replacing weak factory brazed cores with heavy-duty TIG-welded 304L stainless steel tubing featuring robust wall thickness. Internal water deflectors are integrated to increase coolant flow turbulence, significantly improving heat dissipation and thermal shock resistance. Each unit is individually pressure-tested before packaging to ensure absolute sealing integrity under high exhaust temperatures and boost pressures, requiring no custom tuning or performance monitors.

Key Features & Benefits

• TIG-Welded 304L Stainless Tubing: Replaces fragile factory brazed joints with heavy-duty 0.375" O.D. x 0.048" walled stainless steel tubes to eliminate thermal cracking.
• Internal Coolant Water Deflectors: Engineered deflectors boost coolant turbulence inside the core, accelerating heat dissipation and preventing localized hot spots.
• Individual Pressure Testing: Every unit undergoes rigorous pressure and leak testing prior to shipping to guarantee structural reliability.
• No Custom Tuning Required: Direct replacement design operates seamlessly with stock vehicle engine management without throwing check engine lights or setting diagnostic trouble codes.
• Includes O-Ring & Threaded Insert: Supplied complete with necessary mounting hardware for a straightforward replacement process.

Vehicle Fitment & Installation Notes

• Late 2004–2007 Ford F-250 / F-350 / F-450 / F-550 Super Duty – 6.0L Powerstroke Diesel
• Late 2004–2005 Ford Excursion – 6.0L Powerstroke Diesel
• Fits Model Years: Late 2004, 2005, 2006, 2007 (Engine build dates after 09/22/2003)
• Fitment Notice: Engineered strictly for late 2004–2007 models utilizing the square EGR cooler. Does not fit early 2003 to mid-2004 trucks equipped with the round cooler (which require part number 1090201). Always inspect the engine oil cooler for restrictions before installing a new EGR cooler to prevent recurring thermal failure.
• Installation Tip: Drain the coolant system fully, unbolt the intake manifold and up-pipe assembly carefully, and clean all mating surfaces. Always verify engine oil-to-coolant temperature differentials; a clogged oil cooler restricts flow to the EGR cooler and will cause repeat ruptures.
