MA-26 ENGINE MAINTENANCE (F9Q) ● Pour coolant through coolant filler neck slowly of less than (1-3/4 lmp qt) a minute to allow air in system to escape. 3. Fill reservoir tank to specified level. 4. Warm up engine to normal operating temperature reservoir tank ● If coolant overflows reservoir tank filler hole, install reser- 5. Run engine at 3,000 rpm for 10 seconds and return to idle speed ● Repeat two or three times. Watch coolant temperature gauge so as not to overheat the engine. 6. Stop engine and cool down to less than approximately 50 ° C (122 ° F). ● Cool down using a fan to reduce the time. ● If necessary, refill radiator up to filler neck with coolant. 7. Refill reservoir tank to MAX level line with coolant. 8. Repeat steps 5 through 7 two or more times with reservoir tank cap installed until coolant level no longer 9. Check cooling system for leaks with engine running. 10. Warm up engine, and check for sound of coolant flow while running engine from idle up to 3,000 rpm with heater temperature controller set at several position between COOL and WARM. ● Sound may be noticeable at heater unit. 11. If sound is heard, bleed air from cooling system by repeating steps 5 through 7 until coolant level no longer drops. ● Clean excess coolant from engine. FLUSHING COOLING SYSTEM 1. Fill radiator and reservoir tank with water and reinstall reservoir tank cap. 2. Run engine and warm it up to normal operating temperature. 3. Rev engine two or three times under no-load. 4. Stop engine and wait until it cools down. 5. Drain water. 6. Repeat steps 1 through 5 until clear water begins to drain from radiator. Checking Cooling System ELS000PQ WARNING: Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure CHECKING COOLING SYSTEM HOSES Check hoses for improper attachment, leaks, cracks, damage, loose connections, chafing and deterioration. CHECKING RADIATOR Check radiator for mud or clogging. If necessary, clean radiator as follows. ● Be careful not to bend or damage the radiator fins. ● When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator 1. Apply water by hose to the back side of the radiator core vertically downwards. 2. Apply water again to all radiator core surface once per minute. 3. Stop washing if any stains no longer flow out from the radiator. 4. Blow air into the back side of radiator core vertically downwards. ● Use compressed air lower than 490 kpa (5 kg/cm 2 , 71psi) and keep distance more than 30 cm (11.8 in).
