Rated 4 out of 5 by 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.
