What kind of coolant is used for antifreeze?
IAT Coolant. The most common variety of liquid antifreeze is an IAT formula, or Inorganic Additive Technology. ZEREX™ Original Green is an IAT coolant that has been used for decades and is a formula proven to provide unsurpassed corrosion protection.
What should be the freezing point of DOWTHERM SR-1?
DOWTHERM™ SR-1 is not available in concentrations below 25% as ethylene glycol solutions less than 25% may be at risk for bacterial contamination. If you require freeze point protection for temperatures between -28°F and -60°F, contact us to determine a custom concentration.
How does the freezing point of glycol work?
We protect up to the lowest anticipated temperature (also known as the freezing point) by adjusting the antifreeze mix ratio, or the concentration of glycol in the heat transfer fluid. The higher the concentration, the colder the mixture will continue to protect.
What’s the difference between IAT and Zerex Antifreeze?
It’s important to know the differences so you get the correct antifreeze for your vehicle. The most common variety of liquid antifreeze is an IAT formula, or Inorganic Additive Technology. ZEREX™ Original Green is an IAT coolant that has been used for decades and is a formula proven to provide unsurpassed corrosion protection.
What kind of antifreeze do you use on a Jeep Wrangler?
^^^The one on the left is HOAT Antifreeze. It is used in the 2012 and prior! The one on the right is OAT Antifreeze. It is used in the 2013 through 2015 models. Do not use the wrong antifreeze, because they are not compatible!!!!!!!! You are best off, to just purchase from your Jeep Dealer.
How can I check the freezing point of my antifreeze?
Check your antifreeze’s freezing point. You can pick up an inexpensive tool called a hydrometer at any auto parts store that makes use of a float to indicate the freezing temperature of your coolant.
What should the ratio of antifreeze in coolant be?
In some situations, the ratio of antifreeze in the coolant can be increased to as much as 70 percent. A 70/30 mix will lower the freezing point to -67 degrees F and to raise the boiling temperature to 235 degrees F.
What happens when antifreeze is mixed with water?
When mixed in equal parts with water (50/50), antifreeze lowers the freezing point to -35 degrees F and raises the boiling temperature to 223 degrees F. Antifreeze also includes corrosion inhibitors to protect the engine and cooling system against rust and corrosion.
