Changing coolant

Changing coolant  - Working on your vehicle - Maintenance and servicing - Volvo XC90 Owners Manual - Volvo XC90

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.
