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.

  • Fan hub has a dual pattern for 1-1/4" and 1-1/2" center to center fan mounting patterns
  • Pump measures 5.581" from mounting point on block to front of hub flange
  • To end of the hub snout is an additional .710" for an overall length of 6.291"
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. 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
(Part #91015709)

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
