Ignoring your vehicle’s radiator is to risk overheating problems that can lead to catastrophic engine failure. Radiator Relief, from Design Engineering Inc., is a corrosion-inhibitor and anti-foaming agent that you pour into your car’s cooling system. The manufacturer claims the product is 100 percent biodegradable, non-corrosive, non-toxic and is compatible with water and all types of coolants and radiator alloys. Its use will also reduce the amount of scale build-up inside the radiator core and can reduce engine temperatures by as much as 30 F. A 16-ounce bottle of Radiator Relief sells for $10 from www.RadiatorRelief.com or through one of the retail stores listed there.
