Warning | Risk of injury. Skin or eye injuries may result when handling hot or glowing objects. | Wear protective gloves, protective clothing and safety glasses, if necessary. | |
Warning | Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | |
Danger | Risk of death to implant wearers from working on retarder | As a safe distance from the retarder, a minimum distance of 100 cm is to be maintained between the retarder and the body parts of the affected person for people with implants. | |
Warning | Risk of injury to skin and eyes suffering scalding from contact with hot coolantspray. Risk of poisoning from 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. | |

Drain off | |||
1 | Open cap of coolant expansion reservoir and release overpressure in cooling circuit. | For installation location of coolant expansion reservoir, see information of bodybuilder. | |
2 | Set heating to max. heating output and switch on ignition. | Only for engine with heating system. | |
3 | Provide filling unit. | ||
| 000 588 02 82 00 Filling unit | ||
4 | Open drain screw (3) and drain coolant at radiator (2) and collect with filling unit. | Catch coolant with filling unit only. The coolant will be cleaned through a filter during filling. | |
5 | Insert drain hose into coolant drain fitting (5). | Use a commercially available hose as a drain hose. | |
6 | Open coolant drain fitting (5) and drain coolant at engine and collect with filling unit. | Catch coolant with filling unit only. The coolant will be cleaned through a filter during filling. | |
7 | Remove drain screws (6, 8) and drain coolant at retarder (7). | Only for secondary coolant-retarder | |
| Connection fitting for coolant return line on retarder modified | ||
8 | Switch off ignition. | ||
9 | Tighten drain screws (6, 8) at retarder (7). | Only for secondary coolant-retarder | |
| Connection fitting for coolant return line on retarder modified | ||
| |||
Install new sealing rings. | |||

11 | Tighten drain screw (3) at radiator (2). | Drain screw to engine radiator | |
| Check | ||
12 | Check drained coolant for contamination. | In the case of strong fouling, the coolant must generally be replaced. | |
If coolant is severely contaminated | |||
| |||
Deoil engine cooling system. | |||
13 | Check coolant using an antifreeze tester. | See information from body manufacturer. | |
If antifreeze additive concentration is too low | |||
| |||
Correct concentration of antifreeze or replace the coolant. | |||
Filling and bleed using the diagnostic system | |||
14 | Connect vehicle diagnosis system, select filling of coolant circuit and start. | ||

| |||
Connect vehicle diagnosis system, see information of bodybuilder. | |||
15 | Exit vehicle diagnosis system and disconnect. | ||
| Check | ||
16 | Check engine cooling system for leak tightness. | Visual inspection. |
