Loss of coolant

The above vehicles can experience a loss of coolant near the exhaust gas recirculation cooler (EGR cooler).

If you suspect a leak in the cooling system, special attention should be paid to the EGR cooler. A crack in the housing can lead to a slow, gradual loss of coolant.

To remedy the situation, proceed as follows and use a repair kit (picture) comprising a housing, 2 gaskets, and 2 clips:

  • Allow the engine to cool down
  • Remove the EGR cooler housing
    (collect coolant in a drip pan)
  • Remove EGR cooler from the housing
  • Clean sealing surfaces

Use repair kit (part no.: 55590953):

  • Fit EGR cooler in new housing
  • Install cooler housing with the new gaskets
  • Add coolant
  • Bleed cooling system
  • Inspect gaskets for tight fit
