17 00 008 Draining and topping up high temperature coolant (B48)
Special tools required:
- 00 2 030
Carry out repair on the cooling system only after the engine has cooled down.
Attention!
Lifetime coolant filling:
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 part quantities of coolant, replace these quantities which have been drained with new coolant.
Installation note:
Use only recommended coolant. Refer to: RADIATOR - OPERATING FLUIDS
Observe mixture ratio. Refer to specifications in RADIATOR - OPERATING FLUIDS
Protective measures/rules of conduct:
- Wear safety goggles
- Wear protective gloves
- Observe national/country-specific regulations
Attention!
For contamination of the cooling system (e.g. by engine oil), the cooling system must be rinsed with water until all contamination is removed!
Attention!
Risk of skidding due to coolant on the floor.
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.
Necessary preliminary tasks:
- Remove FRONT UNDERBODY PROTECTION.
- Remove stiffening plate. (F23, F33)
