  • If your car operates without issue then no.

    If you operate outside of normal parameters then yes. For example, if you live in Death Valley or you tow heavy trailers up mountains.

  • Yes if u bored and stroke a motor it's best to go with a bigger one so it can definitely cool it down.

  • 2 rows of cores is the max you need but going to a dual pass helps and the more coolant volume the better, but than you need to get into air flow and types of coolant , good old h2O still has the best cooling properties but has the other down falls
