ENGINE COOLING - On-vehicle Service ENGINE COOLING - On-vehicle Service 14-7 3. Remove the cylinder block drain plug from the cylinder block to drain the engine coolant. 4. Remove the reserve tank to drain the engine coolant. 5. When the engine coolant has drained, pour in water from the radiator cap to clean the engine coolant line. 6. Coat the thread of the cylinder block drain plug with the specified sealant and tighten to the specified torque. 3M Nut Locking Part No. 4171 or equivalent 7. Securely tighten the radiator drain plug. 8. Install the under cover. (Refer to GROUP 51 - Front Bumper.) 9. Install the reserve tank. 10. Slowly pour the engine coolant into the mouth of the radiator until the radiator is full, and pour also into the reserve tank up to the FULL line. MITUBISHI GENUINE COOLANT or equivalent Quantity: 6.0 L Caution Do not use alcohol or methanol anti-freeze or any engine coolants mixed with alcohol or methanol anti-freeze. The use of an improper anti-freeze can cause the corrosion of the aluminium components. 11. Install the radiator cap securely. 12. Start the engine and warm the engine until the thermostat opens. (Touch the radiator hose with your hand to check that warm water is flowing.) 13. After the thermostat opens, race the engine several times, and then stop the engine. 14. Cool down the engine, and then pour engine coolant into the reserve tank until the level reaches the FULL line. If the level is low, repeat the operation from step 11. CONCENTRATION MEASUREMENT Measure the temperature and specific gravity of the engine coolant to check the antifreeze concentration. Antifreeze Allowable concentration MITSUBISHI GENUINE COOLANT or equivalent 30 - 60 % Caution If the concentration of the anti-freeze is below 30 %, the anti-corrosion property will be adversely affected. In addition, if the concentration is above 60 %, both the anti-freezing and engine cooling properties will decrease, affecting the engine adversely. For these reasons, be sure to maintain the concentration level within the specified range. 44 ± 5 N·m Water inlet pipe |
