Belt check
Check the belt regularly to make sure it is in good condition and is clean. A worn or dirty belt can cause poor cooling
and low alternator output as well as impair the operation of the power steering and the air conditioning unit.
NOTE:
The drive belt is equipped with a self-tensioning mechanism and requires no adjustment between changes!
WARNING!
The engine must not be running when this check is performed.
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, consult your Volvo retailer.
NOTE:
Do not top off with water only. This reduces the rust-protective and antifreeze qualities of the coolant and has
a lower boiling point. It can also cause damage to the cooling system if it should freeze. Top off with Volvo Genuine
Coolant/Antifreeze only (a 50/50 mix of water and antifreeze).
CAUTION:
The cooling system must always be kept filled to the correct level. If it is not kept filled, there can be high local
temperatures in the engine which could result in damage. Different types of antifreeze/coolant may not be mixed.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the car cools.
