Do not pour coolant into beverage containers. | |
Topical note | Notes on coolant | ||
1 | Open the maintenance door | ||
2 | Unscrew the closing cap (1) | ||
3 | Set the temperature selector knob of the heating system in the maximum heating power and turn on the ignition | ||
4 | Drain the coolant from the cooler | For that, put an outlet hose in the drain neck (3) and loosen the drain plug (2). Collect the coolant in a clean container. | |
5 | Drain the coolant from the engine block | Unscrew the drain plug (4). | |
6 | Detach both coolant hoses (5) in the retarder | Only vehicles with Code (BA9), secondary retarder Voith R 115. | |
Collect the coolant in a clean container. | |||
7 | Unscrew the drain plug (6) in the heat exchanger (7) | Only vehicles with Code (BA1) retarder Voith with optimized power. | |
Collect the coolant in a clean container. | |||
8 | Turn off ignition | ||
Refill | |||
9 | Attach both coolant hoses (5) in the retarder | Only vehicles with Code (BA9), secondary retarder Voith R 115. | |
Check the coolant hoses and the clamps for damages, if necessary, replace them. | |||
10 | Screw the drain plug (6) in the heat exchanger (7) | Only vehicles with Code (BA1) retarder Voith with optimized power. | |

12 | Screw the drain plug (2) in the radiator and remove the outlet hose | .Drain plug on the cooler | |
13 | Check the coolant for contamination | ||
If necessary, in case of intense contamination, the coolant must be completely replaced: | |||
| |||
Degrease and descale the cooling system. | |||
14 | Check coolant with an anti-freeze protection test unit | In case of low anti-freeze protection, correct the anti-freeze content or replace the coolant. | |

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. | |
15 | Fill up with coolant | ||
16 | Start the engine, bleed the cooling and heating assembly | Run the engine for approximately 5 minutes in alternate speeds. Refuel with coolant under operation until the lower edge of the filler neck. | |
17 | Stop the engine | ||
18 | Screw the cap (1) | ||
19 | Check the cooling system for leak-tightness | Visual inspection | |
20 | Close the maintenance cover |
