Opel Astra J - Tab af kølevæske | HELLA

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
