Record low → glycol fraction and volume

Quick Answer

Coolant Mix Calculator: Record low → glycol fraction and volume. Coolant Mix Calculator uses standard everyday life formulas to compute accurate results instantly.

How it works

  1. 1Target freeze point = -15 − 10 = -25 °C
  2. 2Glycol volume fraction 40% (step up until freeze point is met)
  3. 3Concentrate = 10 × 40% = 4 L; soft water = 6 L

Freeze-point table (glycol volume fraction): 13.6% → −5°C, 22% → −10, 30% → −15, 40% → −25, 49% → −35, 55% → −45. Above 60% the freeze point rises again and viscosity hurts cooling — never go past 60%.

Pure ethylene glycol freezes at only about −11.5°C: never fill with undiluted concentrate. Mix with distilled/deionized water only — tap water causes scale and corrosion.

Never mix different colors/formulas (IAT/OAT/HOAT react into sludge). Replace IAT every 2 years or 40,000 km; OAT lasts up to 5 years. Glycol is toxic — collect waste fluid for proper disposal.
