Protective measures/rules of conduct

1. Wear safety goggles
2. Wear protective gloves
3. Observe national/country-specific regulations

Catch and dispose of drained coolant in drip tray (1) and if necessary special tool 00 2 030 (universal hydraulic lifting equipment).

Recycling

Scheme 21

Checking pressure drop in cooling system

Open the sealing cap on the coolant expansion tank. Fit special tool 17 0 101 / 17 0 113 .

BUILD UP EXCESS PRESSURE and wait approx. 2 minutes.

Cooling system is impervious to watertightness if pressure drop is max. 0.1 bar.

Scheme 22

Checking pressure relief valve in sealing cap

Note. While the driving at high ambient temperatures, the design may cause the pressure relief valve in the sealing cap to open slightly and air together with dissolved coolant to escape. This coolant vapour condenses on the surface of the expansion tank and leaves traces of coolant when the vehicle has cooled down. These traces of coolant do not indicate whether the sealing cap is defective or not. When the vehicle has been parked up for an extended period of time, the residual escaping coolant can cause the pressure relief valve in the sealing cap to stick; therefore check the sealing cap again 2 to 3 times. Replace the sealing cap only after you have checked three times and there is an incorrect opening pressure.

Checking pressure relief valve in sealing cap

Screw sealing cap (1) onto special tool 17 0 114 .

Build up pressure with special tool (hand pump) 17 0 101 ; observe pressure gauge to ascertain when opening pressure is achieved.

Compare OPENING PRESSURE OF PRESSURE RELIEF VALVE .
