DRAINING AND REFILLING THE
COOLING SYSTEM
Caution: Do not remove the surge tank cap while
the engine and the radiator are hot. Scalding fluid
and steam may be blown out under pressure.
1. Place a pan below the vehicle to catch the draining
coolant.
2. Drain the coolant.
Remove the surge tank cap (1).
Disconnect the lower radiator hose (2).
Caution: Dispose of the used coolant to a used
coolant holding tank to be picked up with the used
oil for disposal. Never pour the used coolant down
the drain. Ethylene glycol antifreeze is an extremely
toxic chemical. Disposing of it into the sewer sys-
tem or the ground water can contaminate the local
environment.
D102D502
3. Connect the lower radiator hose.
4. Clean the cooling system.
Remove all sludge and dirt from inside the surge
tank. And install the surge tank. Refer to “Surge
Tank” in this section (1).

1D–10 ENGINE COOLING
DAEWOO M-150 BL2
D102D503
Add the clean water to the surge tank (2).
5. Run the engine until the thermostat opens. You can
tell the thermostat is open when both radiator hoses
are hot to the touch.
6. Stop the engine and disconnect the lower radiator
hose to drain the coolant.
7. Repeat steps 3 through 6 until the drained water is
clear and free of coolant and rust.
Notice: Never use an antifreeze mixture more concen-
trated than 60 percent antifreeze to 40 percent water.
The solution freezing point increases above this con-
centration.
8. 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.
9. Fill the surge tank to the specified MAX fill mark on
the outside of the tank.
10. Install the surge tank cap.

SURGE TANK
Removal Procedure
Caution: To prevent personal injury, do not remove
the surge tank cap while the engine and the radiator
are hot, because the heat causes the system to re-
main under pressure scalding fluid and steam may
be blown out under pressure.
1. Drain the engine coolant to below the level of the
surge tank.
2. Remove the surge tank.
Loosen the overflow hose clamps and disconnect
the overflow hoses from the surge tank (1).
Remove the surge tank (2).
3. Clean the inside and the outside of the surge tank and
the surge tank cap with soap and water.
4. Rinse the surge tank and the cap thoroughly.
5. Check the surge tank and the cap for crack or other
damage.
