Danger | Risk of death caused by vehicle slipping or toppling off of the lifting platform. | Align vehicle between vehicle lift columns and position the four support plates at the vehicle lift support points specified by the vehicle manufacturer. | |
Warning | Risk of injury. Moving parts can pinch, crush or, in extreme cases even sever extremities. | No parts of the body or limbs should be within the operating area of mechanical components when moving components. | |
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. | |
Caution | Risk of injury caused by scraping or cutting body parts on sharp vehicle parts | Always wear protective gloves when working on or near sharp and non-deburred vehicle parts. | |

| Check | ||
1 | Check whether vehicle is affected by measure. | Affected vehicles: Check coolant hose at right on radiator for any chafe marks, replace, if necessary (code: VS2KULWASS) | |
For authorized MercedesBenz service partners, only the entry in the Extended VEGA Application (EVA) system, in the "Current" tab, is decisive. An additional test of the affected vehicles in the workshop information system (WIS) or vehicle list is thereby not necessary. | |||
2 | Remove lower engine compartment lining. | ||
| |||
3 | Check coolant hose (1) at right on radiator. | | |
Check coolant hose (1) for possible chafe marks or damage. | |||
If coolant hose (1) is damaged or distance between coolant hose (1) and cable duct (5) is too small, | |||
| |||
take pictures of area, store in a tamperproof manner with the repair order then continue with operation step 4. | |||
If the coolant hose (1) is undamaged and the distance between the coolant hose (1) and the cable duct (5) is sufficient, | |||
| |||
continue with operation step 17. | |||
Attach protective ring (4) to coolant hose (1) | |||
4 | Drain off coolant. | ||
| |||
The coolant may be reused as part of this service measure. | |||
5 | Remove coolant hose (1) at right from radiator. | ||
| |||
| Open, close coolant line coupling | ||
Collect any escaping coolant in a suitable container. | |||
Set of protective caps | |||
Set of protective covers | |||
6 | Remove coolant hose for heating (2) from coolant hose (1). | Only if the coolant hose (1) is damaged and is replaced. | |
| Open, close coolant line coupling | ||
Collect any escaping coolant in a suitable container. | |||
7 | Remove coolant hose (1) from coolant thermostat (3). | Only if the coolant hose (1) is damaged and is replaced. | |
| Open, close coolant line coupling | ||
Collect any escaping coolant in a suitable container. | |||
Dispose of damaged coolant hose (1) properly. | |||
8.1 | Use protective covers to seal openings on coolant hose for heater (2) and on coolant thermostat (3). | Only if the coolant hose (1) is damaged and is replaced. | |
Set of protective caps | |||
Set of protective covers | |||
8.2 | Use protective covers to seal openings on coolant hose (1). | Only if coolant hose (1) is not replaced. | |
Set of protective caps | |||
Set of protective covers | |||
9 | Attach protective ring (4) to coolant hose (1). | To do so, turn over protective ring (4), slide onto coolant hose (1), turn back protective ring (4) and position, as shown. | |
If coolant hose (1) is damaged, | |||
| |||
use new coolant hose (1). | |||
10.1 | Remove protective covers from radiator, from coolant hose for heater (2) and from coolant thermostat (3). | Only if the coolant hose (1) is replaced. | |
10.2 | Remove protective covers from radiator and from coolant hose (1). | Only if coolant hose (1) is not replaced. | |
11 | Install new coolant hose (1) on coolant thermostat (3). | Only if the coolant hose (1) is replaced. | |
| Open, close coolant line coupling | ||
12 | Install new coolant hose for heating (2) on coolant hose (1). | Only if the coolant hose (1) is replaced. | |
| Open, close coolant line coupling | ||
13 | Attach coolant hose (1) at right to radiator. | ||
| Open, close coolant line coupling | ||
| |||
Check position of protective ring (4) on coolant hose (1). | |||
If position of protective ring (4) on coolant hose (1) is not correct, | |||
| |||
position protective ring (4) over cable duct (5) for electrical wiring harness, as shown. | |||
14 | Pour in coolant and bleed engine cooling system. | ||
| |||
15 | Clean sealing surfaces in repair area using lint-free rag. | ||
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. | |
16 | Perform engine test run and inspect repair area for leak tightness. | ||
Install remaining parts | |||
17 | Install lower engine compartment lining. | ||
