Antifreeze Coolant Test StripsFor Most Types of Antifreeze/Coolant Formulations

Available in packs of 6 or 70

To order test strips, call 1-800-748-5781.

A fast, effective and economical method of testing the condition of most all types of antifreeze including propylene glycol, Dex-Cool and conventional ethylene glycol formulations for gasoline, diesel or natural gas engines.

Determines the freeze point, boil point and pH levels so that you can make an instant determination of whether coolant is good for continued use.

Why Use an Antifreeze/Coolant Test Strip?

  • Simple to use
  • A clean and mobile way to test coolant
  • Instant, accurate results
  • Inexpensive

What Information is Determined By Antifreeze Test Strips?

  • Freeze point
  • Boil point
  • pH levels

Why Does the pH Level of Antifreeze Matter?

A pH analysis below 7.5 shows that the coolant has become acidic. A reading above 11 suggests that the antifreeze has become alkaline. Alkaline antifreeze can be corrosive to aluminum. The bottom line is that antifreeze with a pH of below 7.5 and above 11 should be flushed at the earliest opportunity. The color of these Antifreeze Test Strips offers an immediate visual result. No guess-work involved!

What Types of Antifreeze is Suitable for These Test Strips?

Most any type of antifreeze can be analyzed except for Red coolant. Can be used with coolant in gasoline, diesel  or natural gas powered engines. Compatible antifreeze types include:

  • Ethylene glycol
  • Propylene glycol
  • Mix of ethylene glycol and propylene glycol
  • GM Dexcool

How to Use Antifreeze Test Strips

  • Shut down engine. Best results are achieved on a cold engine.
  • Make sure coolant temperature is below 43°C (110°F).
  • Open radiator cap and immerse strip in coolant for one second and remove.
  • Within one minute, match the color change of the strip with the sample colors on the outside of the package.
  • The top test area of the strip shows pH levels.
  • The bottom test area shows freeze and boil status.

Caution: Do not open radiator cap when engine is hot.

A clean, fast and cheap way to test the pH, boil-point and freeze-point of most types of antifreeze.
