Additional Notes
- The Triumph GT6 carries a cooling system capacity of 6.2 liters across all three marks produced from 1966-1973.
- A 6.2-liter coolant capacity places the GT6 in a moderate range for a small-displacement inline-six engine, reflecting the thermal demands of a six-cylinder unit housed in a compact sports car body.
- The MK1, MK2/GT6+, and MK3 variants all share the identical 6.2-liter figure, meaning no cooling system volume changes were introduced across the generational updates spanning 1966-1973.
- All three specifications are listed under normal use conditions, which in coolant service contexts typically refers to standard operating environments without sustained high-load or extreme temperature exposure.
- The 6.2-liter figure represents a full cooling system capacity, the total volume of coolant the system holds when filled, rather than a partial drain-and-refill service quantity.
