pg. 120 Coolant

Check coolant level

The cooling system must be filled with coolant and not leak to operate at maximum efficiency. Check

the coolant level regularly. The level should be between the "MAX" and "MIN" marks on the expansion

tank. The check should be made with particular thoroughness when the engine is new or when the

cooling system has been drained.

Do not remove the filler cap other than for topping up with coolant. Frequent removal may prevent

coolant circulation between the engine and the expansion tank during engine warm up and cooling.

Changing coolant

Normally, the coolant does not need to be changed. If the system must be drained, use the following

procedure:

Draining:

1 Remove the expansion tank cap.

2 Move the temperature adjustment control to max. heat. Open the drain cocks at the rear left of the

engine block and at the bottom right corner of the radiator.

3 Disconnect the lower right radiator hose.

Filling:

4 Close the drain cocks and reconnect the hose.

5 Fill the expansion tank to the MAX mark or slightly above.

6 Run the engine until hot. Check the cooling system connections for tightness. Recheck the coolant

level.

Capacity: 7.4 US qts. (7.0 liters)

Coolant: Volvo Genuine Coolant/Antifreeze only

NOTE: Do not top up with water only. Water by itself reduces the rust-protective and anti-freeze

qualities of the coolant and has a lower boiling point. It can also cause damage to the cooling system if it

should freeze.
