Check Engine Cooling System For Leaktightness - AR20.00-P-1011MND
Engine 276.8 in model 213, 238
| 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 overpressure. Do not pour coolant into beverage containers. Wear protective gloves, protective clothing and safety glasses. |

| 1 | Unscrew cap (1) slowly on coolant expansion reservoir (2) and relieve overpressure | ||
| 2 | Check coolant level and antifreeze content of coolant; correct if necessary | *BF20.00-P-1001-02BA | |
| 3 | Screw tester cap (3) onto coolant expansion reservoir (2) | Fig 1 | |
| 4 | Connect pressure pump (4) at tester cap (3) | Fig 2 | |
| Check | |||
| 5 | Apply a test pressure to the engine cooling system for 2 minutes | Do not exceed the specified test pressure. Damage can occur on the engine cooling system otherwise. Test pressure for pressure-testing the engine cooling system |
