IMPORTANT
•
A high content of chlorine, chlorides and
other salts may cause corrosion in the
cooling system.
•
Always use coolant with anti-corrosion
agent as recommended by Volvo.
•
Ensure that the coolant mixture is 50%
water and 50% coolant.
•
Mix the coolant with approved quality tap
water. In the event of any doubt about
water quality, used ready-mixed coolant in
accordance with Volvo recommendations.
•
When changing coolant/replacing cool-
ing system components, flush the cooling
system clean with approved quality tap
water or flush with ready-mixed coolant.
•
The engine must only be run with a well-
filled cooling system. Otherwise, tempera-
tures that are too high may occur result-
ing in the risk of damage (cracks) in the
cylinder head.
