Additional Notes
- The Audi V8 3.6 cooling system carries a capacity of 10.5 liters, which reflects the total volume of the entire cooling circuit including the engine block, radiator, and expansion reservoir.
- The V8 4.2 in its 1991-1992 form shares the same 10.5-liter cooling system capacity as the 3.6, despite the displacement increase between the two engine variants.
- The 1992-1994 V8 4.2 cooling system capacity drops to 8.5 liters, a reduction of 2 liters compared to the earlier 4.2 variant, indicating a revised cooling circuit design between the two production periods.
- Both V8 4.2 variants carry a 24-month coolant change interval under normal use conditions, meaning standard operating environments without the added thermal or mechanical stress associated with severe-duty cycles.
- No change interval is listed for the V8 3.6 cooling system, whereas the two 4.2 variants both specify a 24-month service cycle, making the interval data exclusive to the later engine configurations in the available specifications.
