Topping Off Coolant - GHG17,BRO-0002; EUROV
MBE900; Gen 5 DD13; Gen 5 DD15
Note: Topping off must be done while the vehicle is off and has had
time to cool down. Topping off should never be done on a warm engine
or a running vehicle.
The coolant level should be checked daily and at each service interval. If topping off is necessary, add coolant which is identical to the initial–fill coolant. Extended Life Coolants (ELC) also known as Organic Acid Technology Coolants (OAT) should be topped-off with a coolant of the same formulation; Standard Life Coolants (SLC) also known as Conventional should also be topped-off with a coolant of the same formulation.
Silicated Organic Acid technology (Si-OAT) should only be topped off with Silicated Organic Acid technology (Si-OAT) listed on DFS 93K217. Do not mix with other coolants even if they are the same color.
