Radiator Relief is simply the best coolant system additive on the market today. It's made for use with water or anti-freeze and is designed to function in two ways: It eliminates high temperatures in your passenger car, street rod, racecar, RV, etc., and will reduce the temp as much as 30 degrees F. It also provides a 50 percent quicker warmup time. This characteristic is not only beneficial to motorsports pros, but also to daily drivers who can enjoy the comfort of heat in half the time on those cold mornings.
