Intercooler – Checking conden-
sate drain for coolant leak and
obstruction
1.
With the engine running, verify that air es-
capes from the condensate drain bore(s) at
driving end, left and right engine side. If no
air escapes:
• Clean condensate drain bores
• Blow out condensate drain bores with
compressed air
2.
If a large amount of coolant escapes, the in-
tercooler is leaking. Contact Service.
