Coolant; Coolant Reservoir - Volvo S40 2005 Owner's Manual

2005 Volvo S40

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, and the level must be between the
MIN and MAX marks. 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. Check coolant
regularly!
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the vehicle cools.
If it is necessary to top off the coolant when the engine is warm, unscrew the expansion tank cap
slowly so that the over-pressure dissipates.
