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
