Rated 4 out of 5 by Great premixed solution Ready to use. No mixing needed. October 10, 2016
Rated 5 out of 5 by Prestone is the best! I'm a Prestone customer for 30 years. It works well on all my cars, protect the radiator and isn't expensive. October 9, 2016
Rated 5 out of 5 by I always go with Prestone 50/50 is very convenient because you don't have to add water. Simply pour in with no worries. Plus, I bought this antifreeze and received a $5 rebate in the mail. (Promo) September 17, 2016
Rated 5 out of 5 by Quality Coolant, leaves zero salt deposits. Pre stone coolant has been around forever now and for good reason, it just works. No matter what type of cooling system you have, this coolant will likely work just as good as any other at less cost. OEM coolant for my car is $26 per gallon, Prestone is $11 and works just as well. After running this coolant for 60K miles, I pulled the head to change the head gasket and there were absolutely no mineral/salt deposits in the water jackets. Perfectly clean! Not to mention that even in the summer heat, a 50/50 mix of this coolant keeps my ECT around 185-190 degrees F with an OEM water pump/radiator. Good stuff! September 12, 2016
