Intercooler – Checking condensate drain line for coolant discharge and obstruction

1. Check drain line for water discharge and obstruction when the engine is running idle. 2. If no air emerges, remove condensate drain line and blow out with compressed air. 3. Replace obstructed drain line by new one. 4. Install condensate drain line. 5. If a large amount of coolant is continuously discharged, the intercooler is leaking. Con‐tact Service.
