Ford Ranger & Mazda BT50 EGR Cooler fitment


It's important that before a replacement unit is fitted that the cause of the original EGR Cooler failure has been determined and that the fault is rectified.  If the original cause of the failure has not been rectified this may void your warranty and lead to major engine damage and costly repairs.

Goss suggest you follow this checklist before replacing the unit.

  • Check / Replace - Engine Radiator, Coolant, Water Pump, Heater & Radiator hoses
  • Check / Replace - Heater Core and confirm heater is functioning – (not by-passed)
  • Check / Replace EGR Valve and ensure EGR system is functioning – (not blanked off)
  • Check for Cylinder Head and Engine Block cracks /damage
  • Check / Repair exhaust leaks
  • Check / Clean Carbon deposit build up in the intake and exhaust manifolds
  • Avoid using highly sulphurous Bio-fuels

Here are some more IMPORTANT tips;

  • We recommend you replace the EGR Cooler mounting bolts or use Loctite (or equivalent) to prevent mounting bolts vibrating loose and possibly causing the cooler to crack. This is a common cause of EGR cooler failure
  • When refilling and bleeding the cooling system please refer to the correct Ford / Mazda workshop procedure.  It is important to ALWAYS use the correct Anti-freeze coolant (WSS-M97B44-D2) or equivalent.  
  • Ensure the heater is in the HOT position and functioning correctly to allow maximum flow through the heater system as these vehicles are known to have repeat EGR cooler failures due to improper functioning cooling systems.
  • The Cooling system MUST be refilled and bled using a Cooling system Vacuum Purge & refill tool.
  • Failure to bleed the cooling system correctly may lead to repeat EGR cooler failure as these units are prone to having air pockets in EGR cooler after replacement.
