ENGINE 111, 271, 604, 605, 606
Shown on engine 111
| Remove/install | |||
| On engine 604 to 606 the pressure loss can be checked through bore for injection nozzle or glow plug. | |||
| 1 | Warm up engine to normal operating temperature (approx. 80°C) and switch off engine | ||
| 2 | Open engine hood | ||
| 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. |
