ENGINE COOLANT REPLACEMENT <BSY>


warning When removing the radiator condenser tank cap, use care to avoid contact with hot coolant or steam. Place a shop towel over the cap and turn the cap anti-clockwise a little to let the pressure escape through the vinyl tube. After relieving the steam pressure, remove the cap by slowly turning it anti-clockwise.
1.Drain the water from the radiator, heater core and engine after unplugging the radiator drain plug and removing the radiator condenser tank cap.

2.Disconnect the engine oil cooler hose and drain the water in the water jacket.
3.Remove the radiator condenser tank and drain the coolant.
4.Install the radiator condenser tank.
5.Drain the coolant then clean the path of the coolant by injecting water from the radiator condenser tank cap area.

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 aluminium components.
By referring to the section on coolant, select an appropriate concentration for safe operating temperature within the range of 50%. Use special tool LLC changer (MB991871) to refill the coolant to the "FULL" line of the radiator condenser tank. A convenient mixture is a 50% water and 50% antifreeze solution.

    Recommended antifreeze: BASF Glysantin Alu Protect Premium/G30
    Quantity: 8.0 L (including 0.7 L in the radiator condenser tank)
9.Tighten the radiator condenser tank cap securely.
10.Turn the A/C switch to OFF position to start the engine and warm up until the cooling fan operates.
note This work is to open the thermostat fully.
11.Rev the engine several times and then stop it. Check that there are no coolant leaks.
12.
caution Do not overfill the radiator condenser tank.
Remove the radiator condenser tank cap with the engine cool, and then refill the engine coolant to the "FULL" line of the radiator condenser tank.
13.Tighten the radiator condenser tank cap securely.
