Empty the engine cooling system
The coolant and eventual corrosion residue are to be completely drained and eliminated ecologically.
1
Remove the filling nozzle lid, in the compensation reservoir.
2
Loosen the drain plug on the engine block and catch the coolant in an appropriate container.
3
Remove the drain plug on the radiator and catch the coolant in an appropriate container.
4
Remove the oil radiator plug (on engines OM 364 A and OM 364 LA) and collect the coolant in a proper container
When discarding the coolant proceed ecologically
Refuel the engine cooling system
5
Install the plugs on the engine block, on the radiator and on the oil radiator . .
6
Prepare the cooling in a separate container, bu shaking it to perfectly homogenize the mixture.
7
Check the concentration of the mix with a hydrometer.
8
If necessary, make the corrections, by adding water or additive until you obtain the prescribed concentration.
9
Refuel the cooling system up to the maximum reference level of the compensation reservoir:
10
Install the filling nozzle lid, in the compensation reservoir.
