MA-18 ENGINE MAINTENANCE (YD22DDTI) REFILLING ENGINE COOLANT 1. Install reservoir tank, radiator lower hose and cylinder block drain plug. Apply sealant to the thread of cylinder block drain plug. ● Use Genuine Liquid Gasket or equivalent. 2. Fill radiator slowly with coolant until coolant spills from the air CAUTION: If the filling rate is too fast, this could lead to air being ● Replace the copper washer of the air relief plug. ● Use genuine Nissan anti-freeze coolant or equivalent mixed with water (distilled or demineralized). MA-15, "RECOMMENDED FLUIDS AND LUBRICANTS" ● Pour coolant through coolant filler neck slowly of less than 2 (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 without radia- ● If coolant overflows radiator filler hole, install filler cap. 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 6. Stop engine and cool down to less than approximately ° 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 radiator cap installed until coolant level no longer drops. 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 with water until water spills from the air relief hole, then close air relief plug. Fill radiator and 2. Run engine and warm it up to normal operating temperature. : 7.8 - 11.8 N·m (0.8 -1.2 kg-m , 69 - 104 in-lb) Air relief plug : : 6.7 - 7.9 N·m (0.68 - 0.81 kg-m, 59 - 70 in-lb) Engine coolant capacity (With reservoir tank): 9.5 (8-3/8 Imp qt) SMA182B Reservoir tank : 0.6 (1/2 lmp qt) SMA412B |
