17 00 005 Draining and adding coolant (M57T2)
Special tools required:
Only carry out repair work on the cooling system after engine has cooled down.
Never reuse used coolant!
When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change the coolant. The cooling system must therefore be drained and refilled.
In the case of other removal work involving the draining of partial quantities of coolant, replace these quantities which have been drained with new coolant.
Installation note:
Use only recommended coolant. See RADIATOR -- OPERATING FLUIDS .
Observe mixture ratio. See RADIATOR -- OPERATING FLUIDS .
Protective measures/rules of conduct:
- Wear safety goggles
- Wear protective gloves
- Observe national/country-specific regulations
Necessary preliminary work:
- Remove CHARGE AIR COOLER
Danger of injury!
Catch and dispose of drained coolant in drip tray (1) and if necessary special tool 00 2 030 (universal hydraulic lifting equipment).
Recycling:
Observe country-specific waste disposal regulations.
Open the sealing cap (1) on the coolant expansion tank.
If fitted, open drain plug on radiator.
On coolant radiators which do not have a drain plug, remove coolant hose.
Open the bleeder screw (1).
Adding coolant:
Use only recommended coolant. See RADIATOR -- OPERATING FLUIDS .
Observe mixture ratio. See RADIATOR -- OPERATING FLUIDS .
Observe capacities . See COOLANT, COOLING SYSTEM TEST, M57T2 .
