17 00 008 Draining and adding coolant in radiator (N62TU, N63)
Special tools required:
Only carry out repair work on the cooling system after the 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 part 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
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:
- Follow notes for CARRYING OUT REPAIR WORK ON THE COOLING SYSTEM .
- Remove UNDERBODY PROTECTION
Draining coolant:
Open sealing cap (1) on coolant expansion tank (2).
Installation note:
Close sealing cap (1) until the arrow marks line up.
If fitted, release coolant drain plug (1) on radiator. For radiators without coolant drain plug, unlock and pull off coolant hose.
Drain, catch and dispose of coolant.
Installation note:
- Replace sealing ring.
- Tightening torque: 17 11 2AZ .
Use only recommended coolant. See RADIATOR -- OPERATING FLUIDS .
Observe mixture ratio. See RADIATOR -- OPERATING FLUIDS .
Observe bleeding instructions without fail.
