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.
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
2010 Audi Q5 Quattro (8RB) V6-3.2L (CALB) Page 737
fill the coolant system using the repair manual procedures in ElsaWeb.
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.
