Danger! | Risk of injury to skin and eyes caused by scalding from contact with hot coolant spray. Risk of poisoning caused by swallowing coolant. | Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. Wear protective gloves, protective clothing and safety glasses. | |
| Notes on coolant | ||
1 | Remove maintenance flap (3) | ||
2 | Turn cooling system cap (1) on engine radiator (2) a half turn counterclockwise, relieve the pressure and then unscrew the cooling system cap (1) | ||
3 | Check coolant level in expansion reservoir (2), correct if necessary. | The engine coolant level in the coolant expansion reservoir (2) must be positioned at the max. marking. | |
| Coolant specifications | Sheet 310.1 | |
| Anticorrosion/antifreeze agents (Sheet 325.0) | Sheet 325.0 | |
4 | Attach pressure pump on expansion reservoir (2) | | |
5 | Apply a pressure of a max. of 1.6 bar to the cooling system | Observe pressure gauge for pressure pump. | |
| |||
6 | Remove interior flap above engine | If a pressure drop was established in the cooling system. | |
Danger! | Risk of death caused by vehicle slipping or toppling off of the lifting platform. | Align vehicle between columns of vehicle lift and position four support plates at vehicle lift support points specified by vehicle manufacturer. | |
7 | Raise vehicle using the vehicle lift and remove underfloor paneling | If a pressure drop was established in the cooling system. | |
Cordless drill/driver, cordless drill | |||
8 | Check all components of cooling system for leaks; establish coolant loss and remove it | If a pressure drop was established in the cooling system. | |
9 | Lower vehicle with vehicle lift | ||
10 | Disconnect pressure pump on expansion reservoir (2) and check coolant level in expansion reservoir (2); correct if necessary | After removing leakage in the cooling system. | |
The engine coolant level in the coolant expansion reservoir (2) must be positioned at the max. marking. | |||
