Engine Sealer
Moroso ceramic engine seal coats and seals radiators and cooling systems. Seals minor cracks in engine head and block.
 The best Chemical Sealer you can buy to stop cooling system leaks. Works equally well in aluminum or cast iron blocks. Cooling system must be thoroughly clean before use. Does not work with antifreeze. If this doesn't stop the leaks, find yourself a welder!
Water Wetter
Red Line Water Wetter Super Coolant additive isa unique wetting agent which reduces coolant temperatures by as much as 20 F. This is a liquid coolant treatment product which is designed to be added to solutions of antifreeze and water to help improve the heat transfer properties of glycol-based antifreeze. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Improves the ability of coolant to wet heat transfer surfaces by 50%.
 Reduces or eliminates bubbles that form on hot metal surfaces to reduce coolant temperatures by up to 20. Superior heat transfer properties compared to glycol-based antifreeze. Compatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems. Improves heat transfer and reduces cylinder head temperature. Designed for use with all modern aluminum, cast iron, copper, brass and bronze cooling systems. Cleans and lubricates water pump seals. Reduces cavitation and complexes with hard water to reduce scaling. Does not lower cooling system below the thermostatically-controlled temperature. 12 fl. oz. bottle treats 12-16 quarts.
