Checking and topping up the
coolant
When topping up the coolant, follow the
instructions on the packaging. It is important
that the mixture of coolant concentrate and
water is correct for the prevailing weather
conditions. Never top up with water only. The
risk of freezing increases with both too little
and too much coolant concentrate.
Important!
Always use coolant with anti-corrosion
agent as recommended by Volvo. New
cars are filled with coolant that can
withstand temperatures down to
approximately -35 °C.

See the capacities on page 215.
Check the coolant regularly
The level should lie between the MIN and
MAX marks on the expansion tank. If the
system is not filled sufficiently, high local
temperatures could occur, causing a risk of
damage (cracks) to the cylinder head. Top up
the coolant when the level falls to the MIN
mark.
NOTE! The engine must only be run with a
well-filled cooling system. High temperatures
can occur, causing a risk of damage (cracks)
to the cylinder head.
WARNING!
The coolant may be very hot. If the coolant
requires topping up when the engine is at
operating temperature, unscrew the
expansion tank cap slowly to gently
release the overpressure.
Checking and topping up the
brake and clutch fluid
The brake and clutch fluid have a common
1
reservoir . The fluid level must be between
the MIN and MAX marks. Check the level
regularly. Change the brake fluid every other
year or at every other regular service.
See the capacities and recommended fluid
grade on page page 215.
The fluid should be changed annually on cars
driven in conditions requiring hard, frequent
1. Location dependent on whether car is
left or right-hand drive.
