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. | |
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. | |
Warning | Risk of injury caused by body parts being pinched or crushed as cab is tilted | Ensure that no one is within the tilting range of the cab as it is being tilted. Always tilt the cab all the way to the end position and secure it with the safety strut. | |

| Install | ||
1 | Tilt cab. | ||
2 | Remove soundproofing (5). | Only if soundproofing (5) is installed. | |
3 | Drain off coolant. | ||
| |||
4.1 | Remove coolant drain fitting from crankcase and replace with connection fitting (6). | ENGINE 471.9, 473.9 | |
Connection fitting to crankcase | |||
4.2 | Remove coolant drain fitting from oil/coolant module and replace with connection fitting (6). | ENGINE 470.9 | |
Connection fitting on oil/coolant module | |||
5 | Install coolant filter (1) with bracket (2). | ||
Connection fitting to coolant filter | |||
6 | Connect coolant filter (1). | ||
7 | Leave bore (7) of soundproofing (5) open at side as shown. | Only if soundproofing (5) is installed. | |
8 | Cut off corner (5.1) of soundproofing (5) at line (8) and deburr soundproofing (5). | Only if soundproofing (5) is installed. | |
9 | Install soundproofing (5). | Only if soundproofing (5) is installed. | |
10 | Check all retrofitted component parts for unobstructed movement and lack of chafing. | Due to the variety of the variants it can be necessary to adapt the displayed routing of the coolant hoses to the existing as-built configuration. Furthermore collisions with already mounted assembly parts should be avoided. If necessary alter the holder or routing of the electrical line. | |
11 | Tilt back cab. | ||
12 | Fill in coolant. | ||
| |||
13 | Perform engine test run and check coolant filter (1) and all newly routed hoses for leak tightness. | Visual inspection. | |
If a leakage is found, | |||
| |||
Tilt cab and eliminate leakage. | |||
