How many bottles of coolant do I need?



Use one bottle of WaterWetter® Coolant for most passenger cars and light trucks, treats 3 to 5 gallons or 13.2 to 15.9 liters. Vehicles with larger cooling systems should use two bottles of WaterWetter® Coolant. Small cooling systems should use 1oz (3 to 4 capfuls) per quart of WaterWetter® Coolant.

SuperCool Coolant with WaterWetter® - Convenient, pre-mixed coolant for motorcycles, ATVs, karts, etc.-pour and go! Blended with purified, deionized water and proper WaterWetter percentage. Reduces rust, corrosion and electrolysis, cleans and lubricates water pump seals. Compatible with all antifreeze and coolant. Satisfies ASTM D2570 and ASTM D1384 corrosion tests for glycol-based antifreezes.

Commercial Vehicle Coolant WaterWetter® - Designed for heavy-duty diesel engines which use more than 33% antifreeze or a supplemental corrosion package. Similar properties and benefits to regular WaterWetter, but lacks rust and corrosion inhibitors. Diesel road cars and light trucks (equipped with Cummins, Duramax, and PowerStroke engines) should use regular WaterWetter to ensure proper rust and corrosion protection. Typical diesel commercial vehicle requires one bottle, treats up to 15 gallons.
