Venting Cooling System And Checking For Leaks

Warning:
Danger of scalding!
Only perform these tasks on an engine that has cooled down.

Check cooling system for leaks. Top up coolant.





To ensure the cooling system is properly vented, it is absolutely essential to follow the steps below:
1. Open cap on coolant expansion tank.
2. Turn on ignition
3. Set heating controller to maximum temperature
4. Set fan to low setting. This opens the heating valves and starts the auxiliary water pump.
5. Carry out filling procedure slowly
6. Close vent plug when bubble-free coolant emerges
7. Fill expansion tank until full.
8. Close coolant expansion tank
9. Allow engine to warm up until thermostat opens





Allow engine to cool down before checking coolant level. Coolant temperature must not exceed 30°C. If ambient temperature exceeds 30°C, allow engine to cool down at least to ambient temperature. Check coolant level; if necessary, top up coolant until liquid level reaches marking on coolant expansion tank.

Note: The tank mark indicates the fluid level at approx. 20°C. Use only recommended coolant.
