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

Rated 5 out of 5 by SAVED MY JEEP!! Was dealing with an overheating issue and located a Pep Boys near me. I added the Coolant and determined that the issue was more serious. After having the radiator fan assembly replaced, I look back and am happy I spent that $12 - otherwise I could have lost my Jeep and jeopardized the safety of my family. August 14, 2016
