In a word, NO. Typically a Be Cool radiator only costs about 10% of what a customer has invested in his engine (i.e. $7,500 engine, $750 radiator) yet it adds immeasurably to the enjoyment and usability of his vehicle. It also is a very effective insurance policy. If a customer has more than $7,500 invested in his engine, the Be Cool radiator is an even better buy, percentage wise.
