Extensive testing confirms Purple Ice reduces coolant temperatures better than comparable products while providing extra corrosion protection. For example, the average operating temperature of a 350 c.i.d. V8 engine (equipped with 160Â¬âˆž thermostat) when dyno-tested with different coolants are:
1 oz. / quart of cooling system capacity
2 oz. / quart of cooling system capacity
*minimum of 20% antifreeze is recommended in street-driven vehicles.
