emerges from the condensate drain line at
driving end, left and right engine side. If no
air escapes:
2. Clean condensate drain line(s) and blow
out with compressed air.
3. Replace clogged condensate drain line(s)
by new one(s).
4. Install condensate drain line(s).
5. If a large amount of coolant is continuously
discharged, the intercooler is leaking. Con‐
