Changing coolant
Every two years or 30,000 miles (50,000 km) the cooling system should be drained, flushed and refilled.
Remove the expansion tank cap. Open the drain cocks on both sides of the engine block and disconnect the lower radiator hose.
Fill coolant through the expansion tank. The heater controls should be fully open when draining and filling.
Add coolant until the level is up to the MAX mark or slightly above.
Start engine and run until hot. Check the cooling system connections for tightness. Also re-check the coolant level.
Capacity: See "Specifications"
Coolant: Volvo Coolant type C (blue green)
CAUTION
The cooling system must always be kept filled to correct level.
If it is not kept filled, there can be high local temperatures in the engine which could result in damage.
Top up with coolant
Top up with coolant by filling the expansion tank when level is at the "Min" mark. Use a mixture of 50 percent anti-freeze/summer coolant
and 50 percent water all the year round. Top up to the "Max" mark.
If the engine is warm, and you are going to top up coolant, unscrew the cap slowly in order to allow any excess pressure to escape.
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.
pg. 117 Drive belts
Checking the belt tension
The belt tension can be checked by depressing the fan belt (engine not running!) at a point midway between the alternator and fan. It should
be possible to press down the belt about 1/4"-3/8" (5-10 mm). This also applies to other drive belts on the engine.
Belt check
Check the belts regularly to make sure they are in good condition and are clean. Worn or dirty belts can cause poor cooling and low
alternator output as well as impair the operation of the power steering and the air conditioning unit.
