Test Operation - Mitsubishi S6B Operation & Maintenance Manual

Test operation

To conduct a test operation, follow the procedures below.
Note: For engine operation, refer to
Starting and stopping
1. Start the engine.
2. Operate the engine at low idling speed under no load for 5 to 10 minutes for a warm-up operation.
3. Stop the engine.
Inspection
1. Leave the engine be stopped for about 30 minutes.
2. During this period, check the engine and surrounding area for leaks of fuel, engine oil or coolant.
3. At 30 minutes after the engine stop, check the oil level with the oil level gauge.
4. If the oil level is low, add engine oil from the oil filler. Be sure to use the engine oil of the same brand and type.
5. Open the radiator cap and check the coolant level.
Remove the radiator cap only after the engine has cooled to room temperature. Place a waste cloth over the cap,
and loosen the cap about a half-turn or stand the lever to the upright position to release internal pressure. Opening
the radiator cap while the engine is hot causes steam and hot coolant to spray out and may result in skin burns.
6. If the coolant level is low, add coolant to the specified level.
If the engine is equipped with a reserve tank, fill the reserve tank with coolant to the full level as well.
Always use the coolant with the same LLC concentration.
