Changing coolant
Normally, the coolant does not need to be changed. If the system must be drained, consult a trained and qualified Volvo service technician.
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 expansion tank cap
while the engine is warm. Wait until the
engine cools.
• If it is necessary to top off the coolant
when the engine is warm, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.
