General
General
Depending on the motorisation, there will be one
or two coolant expansion tank(s) in the engine
compartment. Check the coolant levels and top
up.
Coolant is a mixture of water and an additive.
Not all commercially available additives are suita‐
ble for the vehicle. Do not mix additives of differ‐
ent colours. Comply with the 50:50 mixing ratio
of water to additive. Information regarding suita‐
ble additives is available from a Service Partner of
the manufacturer or another qualified Service
Partner or a specialist workshop.
The coolant level is shown by Min and Max
marks. The Min and Max marks are located in
different positions depending on the coolant
tank.
