It's time to change the coolant in my 850. Last time I did it, I bought (and paid through the nose for) a gallon of genuine Volvo coolant at my dealer. I was debating whether to use an aftermarket brand this time as I was looking at the empty Volvo coolant container that I still had. Turns out it has an ingredients list:
Ethylene glycol (107-21-1)
Diethylene glycol (111-46-6)
Sebacic acid (111-20-6)
Sodium hydroxide (1310-73-2)
2-Ethyhexanoic acid (149-57-5)
Corrosion inhibitors
Defoamer
Silicates and dyes
If anyone knows of an aftermarket brand that has the same chemical makeup, please let us know.
