Scheme 17

1. Drain the water from the radiator, heater core and engine after unplugging the radiator drain plug and removing the radiator cap.
2. Remove the water feed hose B, and drain the coolant in the water jacket.
3. Remove the radiator condenser tank assembly and drain the coolant.
4. Drain the coolant then clean the path of the coolant by injecting water into the radiator from the radiator cap area.
5. Install the water feed hose B.
6. Securely tighten the radiator drain plug.
7. Assemble the radiator condenser tank assembly. 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 corrosion of the aluminum components. If the coolant contact the PremAir® direct ozone reduction (DOR) radiator, wash it with water at once.

8. By referring to the section on coolant, select an appropriate concentration for safe operating temperature within the range of 30 to 60 %. Use special tool MB991871 to refill the coolant. A convenient mixture is a 50 % water and 50 % antifreeze solution [freezing point: -31°C (-24°F)]. Recommended antifreeze: Long Life Antifreeze Coolant or an equivalent Quantity: 9.5 dm 3 (10.0 quarts) 10.0 dm 3 (10.6 quarts) < Vehicles with Towing Package or DOR radiator >
9. Reinstall the radiator cap.
10. Start the engine and let it warm up until the thermostat opens.
11. After repeatedly revving the engine up to 3,000 r/min several times, stop the engine.
12. Remove the radiator cap after the engine has cooled, and pour in coolant up to the brim. Reinstall the cap. CAUTION: Do not overfill the radiator condenser tank assembly.
13. Add coolant to the radiator condenser tank assembly between the "FULL" and "LOW" mark if necessary.

A << THERMOSTAT INSTALLATION

Install the thermostat so that the jiggle valve is facing straight up. Be careful not to fold or scratch the rubber ring.

Scheme 21

1. Immerse the thermostat in water, and heat the water while stirring. Check the thermostat valve opening temperature. Standard value: Valve opening temperature: 82 ± 1.5°C (180 ± 3°F)
2. Check that the amount of valve lift is at the standard value when the water is at the full-opening temperature. NOTE: Measure the valve height when the thermostat is fully closed, and use this measurement to compare the valve height when the thermostat is fully open. Standard value: Full-opening temperature: 95°C (203°F) Amount of valve lift: 9.0 mm (0.35 inch)
