Identifying and Mixing Factory Fill Engine Coolants
1. Based on its color, identify
which coolant the vehicle was
filled with from the factory
(Figure 1).
Tip: Figure 1 is shown
for color identification only;
coolant packaging may vary.
Figure 1. The color of each type of engine coolant. G11 (greenblue), G12 (red), G12+, G12++ and G13 (purple).
2. Using the chart at right,
determine if the vehicle has
the correct coolant (Figure 2).
If a vehicle is found to have
the incorrect coolant, drain
and fill the coolant system
using the repair manual
procedures in ElsaWeb.
Figure 2. The table identifies which Service coolants (left) can be

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).
Note:
W12 6.3 engines require special G13 coolant only: G A13A8JM1. No other coolant is allowed, and
no other coolant can be mixed with this 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 ElsaWeb 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 ElsaWeb.
Tip: Cooling system drain and fill due to coolant mixing, or incorrect coolant, is not covered by
warranty.
Warranty
This TSB is informational only and not applicable to any Audi warranty.
Required Parts and Tools
No special tools required.
