Q & A

What's in the Box

How handy is this! The built-in calibrated thermometer on this chrome-plated 16 lb. radiator cap makes it easy to check your coolant temp - and to know when its safe to remove the cap. Fits radiators on most domestic vehicles.

  • Helps to prevent burn injuries
  • Integrated coolant reclamation valve works great with your coolant recovery system
  • Your radiator can reclaim coolant from your overflow bottle
  • Wide 30° to 270° F temperature range
  • Calibrated in centigrade and Fahrenheit
  • Color-coded temperature ranges
  • Chromed crown with a colored trim ring

Notes

  1. Check the Thermo Cap temperature indicator to determine if the coolant is cool enough to make removing Thermo Cap safe. If the coolant is very hot, then thoroughly rinse the radiator with cool water, until the coolant temperature drops into a cooler safe zone.

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
