Preliminary Work

Information 

• Cooling systems with thermal management (controlled thermostats or coolant valves for controlling engine temperature) must be vacuum-filled. 
• The thermostat must not be activated or electric current must not be applied to the thermostat since this can cause irreparable damage to the thermoelectric couple. 
• Filling with a watering can only does not always guarantee a complete fill (trapped air - overheating). 
• Clamps on cooling system components should be examined carefully following refilling (check the coolant level while cold and top up several times as required). 
• Clamps on cooling system components must also be vacuum-filled if significant amounts of coolant are drained. Drain at least two litres of coolant for vacuum-filling because otherwise the correct vacuum cannot be built up. 

1. Open the bonnet.
