3 Use a reputable cleaner to clean

the cooling system. Follow the

recommendations that come with the

cleaner.

4 Drain the cleaner and flush the cooling

system with clean water.

5 Fill the cooling system with clean water

and operate the engine until the coolant

temperature has reached 120 to 150

(50 to 65

C).

6 Drain the water and flush the cooling

system with clean water.

7 Again, fill the cooling system with

clean water and operate the engine until

the coolant temperature has reached

120 to 150

F (50 to 65 C).

8 Drain the water and flush the cooling

system with clean water.

9 Fill the cooling system with pre-mixed

Extended Life Coolant. Check the

specifications section for refill quantity.

10 Attach label to the coolant surge tank

to indicate that the system is now filled

with Extended Life Coolant. The label

can be ordered from your Volvo Truck

dealer spare parts department.

Note: When changing over from standard

to extended life antifreeze, tighten all hose

clamps and fasteners in the cooling system.

Extended life coolant tends to leach out

deposited silicate and leaks may appear.
