Rated 5 out of 5 by great having 50/50 antifreeze makes filling up easier. i don't have to add antifreeze and distilled water separately. August 21, 2016
Rated 5 out of 5 by Exactly what I was looking for. Prestone 50/50 Antifreeze is a staple when you have a car with a quarter million miles on it. August 15, 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

Rated 5 out of 5 by This product is easy to use. A Pep Boys employee recommended which antifreeze would be good for a 97' Landcruiser. She was very helpful and informative. Put antifreeze (coolant) in car and car works great, thanks! November 9, 2015
