Antifreeze: Which Brand? Mix with Water?
Why Use Volvo Brand Coolant (Antifreeze)?
If you have a non turbo car then youcan use the regular prestone. Prestone is an OAT technology (Organic acid technology) coolant. A Hybrid OAT (a mix of oat and other ingredients )is called a HOAT- Hybrid OAT. A HOAT is used in modern diesel engines and other turbos as well as all BMW and Mercedes. (Did you ever notice that BMW coolant and Volvo coolant are exactly th same). Volvo HOAT contains Sebacic acid and some silicates on top of the normal OAT ingredient of 2 -EHA . These are the chemicals that make a difference o keeping it from boiling over and repairing damage to aluminum at a molecular level.

My coolant is leaking from my car… BUT has not over heated. I need to know how I fix my leak. It was barely leaking. I just kept adding coolant. I need to know how to fix this problem. I took it to the shop but they couldn’t figure it out either. Should I just repair my radiator? or just seal it? – Thank You
