Redline 80204 Details

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 12-16 quarts

It Really Does Work

My '81 El Camino's 350 V8 runs very hot with the AC on in traffic. I have a HD wide aluminum rad, an electric puller fan & a flex fan. Frustrating until I read a bunch of reviews on this product. Most who use it with 50/50 antifreeze say it doesn't do much. Some who use it with 30% antifreeze say it does a little & some say it works, but everybody who uses it with distilled water says it works. So I carefully & thoroughly flushed my system & added it to straight distilled water. I was skeptical but it dropped my temp down to 205 in traffic with the AC on & if I turn on the electric fan it goes down to 190 & as soon as I get out of town it runs 175 (a 160 Tstat) all day. Problem not fixed but a surely good work around. Speedway had best price & a fast ship.

I would buy this again,

Although I would buy this again , I need a little more testing . My engine runs at 180, but on a hot day (90s) and above it gets up to 220 . I know this is not all that bad. Just don't like it up there. We'll see how the summer heat does with is stuff.

can't believe what I'm seeing. I know it's not that hot out yet but it's taking a long time to get the temperature up to 180. I can't wait until summer is here.

Will this help lower the coolant temp when added to coolant or just when added to water alone.

How is this used with antifreeze? Do you reduce the amount of antifreeze by the quantity of water wetter used?
