Q & A

What's in the Box

These pumps are assembled with 356-T6 heat treated aluminum castings. Precision CNC machined components. The fan hubs are 1/2" thick and machined from billet steel. These pumps are preferred by many top engine builders for higher RPM applications.

These Stage 3 water pumps feature 1/2" thick steel fan hub with set screw for positive positioning and 356-T6 heat treated aluminum casting. The S/B Chevy pump has an extra rigid cam stop with a 3/8" adjusting screw. The extra material adjacent to the block mounting bolts allows drilling and tapping up to 1/2" NPT holes for external cooling lines on S/B Chevy. There is higher flow and pressure for better cooling as well as equal flow to right and left cylinder heads. The 3/4" bearings offer 5 times the strength of standard bearings. Precision impeller installed to exacting tolerances. One year manufacturers warranty.

Red Line 80204 Water Wetter Coolant Additive
                        

Red Line Water Wetter Super Coolant additive is a 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 12-20 quarts
