- Remove the surge tank clip.
- Place a pan below the vehicle to catch the draining coolant.
- Remove the radiator outlet hose.
- Catch the escaping fluid in a drain pan.
Warning: Dispose of the used engine coolant properly. Store the used coolant in a used coolant Holding Tank awaiting proper disposal or recycling. Do not pour used coolant down the drain. Ethylene glycol antifreeze is a very toxic chemical. Disposal into the sewer system or into ground water is both environmentally irresponsible and illegal
Note: Dispose the collected coolant to the designated area.
- Remove all sludge and dirt from inside the surge tank.
- Install the radiator outlet hose.
- Fill the tank slowly so that the upper reservoir hose remains above the water line. This allows the air inside the cooling system to escape.
- Start the engine.
- Run the engine until the thermostat opens. You can tell the thermostat is open when both radiator hoses are hot to the touch.
- Stop the engine.
- Repeat steps 1 through 10 until the drained water is clear and free of coolant and rust.
- Fill the cooling system through the surge tank with a mixture of ethylene glycol antifreeze and water. The mixture must be at least 50 percent antifreeze, but not more than 60 percent antifreeze for cold weather operation.
- Fill the surge tank to the specified MAX fill mark on the outside of the tank.
