Cooling System & Antifreeze
Ethylene-glycol antifreeze protection by mixture ratio. A 50/50 mix is the standard all-season blend; never exceed about 70% glycol.
Antifreeze (Ethylene Glycol) Protection
| Glycol % | Freeze Point | Boil Point (15 psi cap) |
|---|
| 40% | −12°F (−24°C) | 259°F (126°C) |
| 50% | −34°F (−37°C) | 265°F (129°C) |
| 60% | −62°F (−52°C) | 270°F (132°C) |
