Draining and Filling Cooling System (L61)

Draining Procedure


<TABLE border=0 cellSpacing=10 cellPadding=1><TBODY><TR><TD vAlign=top>CAUTION:</TD><TD vAlign=top>With a pressurized cooling system, the coolant temperature in the radiator can be considerably higher than the boiling point of the solution at atmospheric pressure. Removal of the surge tank cap, while the cooling system is hot and under high pressure, causes the solution to boil instantaneously with explosive force. This will cause the solution to spew out over the engine, the fenders, and the person removing the cap. Serious bodily injury may result.</B> </TD></TR><TR><TD vAlign=top>Notice:</TD><TD vAlign=top></B>If the procedure below is not followed a low or high coolant level condition and/or vehicle damage could result.</TD></TR></TBODY></TABLE>

1. Park the vehicle on a level surface.
2. Remove the surge tank cap.
3. Raise and support the vehicle. Refer to Vehicle Lifting.
4. Place a drain pan under the drain ****.
5. Open the radiator drain ****.

1. Close the radiator drain ****. Tighten to 2 Nm (18 inch lbs.) .
2. Install the water pump drain plug if necessary. Tighten the water pump drain plug to 22 Nm (16 inch lbs.) .
3. Lower the vehicle.
4. Fill the cooling system.
5. Slowly add a mixture of 50/50 DEX-COOL antifreeze and deionized water to the cooling system until the coolant level reaches and maintains the top of the surge tank label.

<TABLE border=0 cellSpacing=10 cellPadding=1><TBODY><TR><TD vAlign=top>Important:</TD><TD vAlign=top></B>It is necessary to maintain the coolant level at the top of the surge tank label to insure all the air has been purged from the cooling system.</TD></TR></TBODY></TABLE>

1. Install surge tank cap.
2. Start the engine.
3. Run the engine at 2,000 - 2,500 RPM until engine reaches normal operating temperature.
4. Allow the engine to idle for 3 minutes.
5. Shut the engine off.
6. Allow the engine to cool.
7. Top off the coolant as necessary.
8. Inspect the cooling system for leaks.
9. Rinse away any excess coolant from the engine and the engine compartment.
10. Inspect the concentration of the engine coolant using J 26568.
