Required amount of antifreeze to protect cooling systems at specific temperature ratings can be estimated from the charts below:
- tC = 0.56 (tF - 32) = 5/9 (tF - 32)
- 1 Gallon (U.S.) = 3.785x10-3 m3 = 3.785 dm3 (liter) = 231 in3 = 0.13368 ft3 = 4.951x10-3 yd3 = 0.8327 Imp. gal (UK) = 4 Quarts = 8 Pints
Never use more than 70% antifreeze in a cooling system.
