*Notes

*Nominal refill capacities are shown. A variation may be observed from vehicle to vehicle due to manufacturing tolerance and refill procedure.

** Gelling will occur if mixing different antifreeze formulas. Complete cooling system flush must be performed to evacuate all remaining old antifreeze before adding different antifreeze formula

***If vehicle previously equipped with (green) 3 Year Antifreeze, recommended replacing with (pink/orange) 5 year 100,000 mile formula, only after evacuating all previous antifreeze

**** DOT 4 Brake fluid may be used if DOT 3 cannot be found. DOT 4 brake fluid has shorter service life
