Rated 5 out of 5 by from Excellent coolant , excellent value With all the coolants available out there, why pay more when you can get the same exact thing for less. No sense in spending more than you have to.

Rated 3 out of 5 by from Average I bought it thinking it was blue antifreeze. It was actually green. The product said it could be mixed, but i did not want to possibly void my warranty.

Rated 4 out of 5 by from Just as good as the top name brands. My daughter in college came home complaining how her Altima was running rough and that the air conditioning was not cool. Come to find out that she was low on coolant/ antifreeze in the reservoir. Bought some from my local Pep Boys and have not had any problems since. Lower priced with high qualities. Good job Proline.
