Charge-air cooler, checking wa-
ter drain for coolant leakage
and obstruction
1.
With the engine running, verify that air
emerges from the condensate drain bore(s)
at driving end, left and right engine side. If no
air escapes:
• Clean condensate drain bore(s)
• Blow out with compressed air
2.
If a large amount of coolant is continuously
discharged, the charge-air cooler is leaking.
