Charge-air cooler – Checking condensate drain for water discharge and obstruction

1. With the engine running, check if air emerges from drain bore(s) on the left and right sides on engine driving end. Result: If no air emerges: • 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. Contact Service.

1. Remove injectors (→ Page 147). 2. Bar engine manually (→ Page 132). 3. Bar engine with starting system to blow out combustion chambers (→ Page 132). 4. Install injectors (→ Page 147).
