Technical Service Bulletin Note: Coolants can be mixed, as described in the chart, but it is always best practice to change the coolant due to reduced corrosion protection when coolants are mixed (exception: G12++ and G13 are fully compatible). Only use distilled water for mixing coolant. Note: When the coolant is changed due to a cooling system issue, the cooling system should be drained using the repair manual procedures in Elsa and refilled with water and the engine run for 15 minutes with the heater on to remove any residual coolant. Then drain and fill the system to the freeze protection ratio listed in Elsa. Tip: Cooling system drain and fill due to coolant mixing, or incorrect coolant, is not covered by warranty.
