| Testers are engaged in measuring the concentration of chemicals in the coolant, the most common being ethylene glycol, which is divided into silicate and organic acids (OAT). These are suitable for most cars built after 1998.
To test the coolant mixture, take a sample from the cooler or coolant reservoir, whichever is lighter. Allow the engine to cool before removing the radiator or coolant cap. When the engine is cold, open the lid and take a sample of coolant from the tube.
Relying on AutoZone is child’s play for the right tools and testers. We have the right frost protection testers, radiator rinse kits and anything else that comes to mind. If you need a tool but don’t want to buy it, you can try our LoanATool program.
Prestone Antifreeze / Coolant Tester is a professional tester that easily tests antifreeze / oil protection. It also allows a visual check of the antifreeze during the test. This is an inexpensive way to check the condition of your car’s antifreeze / coolant.
Fortunately, there are several reliable ways to judge the quality of antifreeze.
- Use CoolTrak Coolant Test Strips to test a variety of ethylene glycol or propylene glycol based coolants.
- Increase accuracy by using a refractometer.
This is where antifreeze comes in. Mixed in equal parts (50/50) with water, the antifreeze lowers the freezing point to 35 ° F and raises the boiling point to 223 ° F. Antifreeze also contains corrosion inhibitors to protect the engine and cooling system from rust and corrosion. .
Open the bonnet and look for the engine coolant reservoir. It is often transparent white in color and there are pipes connecting it to the radiator. The tank has a marked filling area on the side. When the engine is cold, the coolant level should reach the cold fill line.

Start your model’s engine to remove air bubbles from all of the different cookers in your system.
Can I also remove the coolant overflow tank cover and fill it with the radiator cap without running the engine?
Yes, it is possible.
The coolant consisting of antifreeze and tap water, solution 5050, lasts about 3 years. The coolant consisting of antifreeze and distilled (deionized) water, solution 5050, has a shelf life of approximately 5 years.
Concentrated engine coolant (ethylene glycol) has a low heat transfer capacity. In hot weather, it does not effectively transfer heat from the engine block. The cooler and fan do not effectively dissipate heat transfer to the atmosphere. The engine overheats in heavy / slow traffic.
When checking the coolant level when the engine is cold, the coolant level should be at or above the minimum or fill line on the clear fill tank. If you are checking the coolant level when the engine is hot, the coolant level should be at or just below the maximum limit.
Use an antifreeze hydrometer. If it’s a float, take the coolant from the top tank, measure where the float breaks the liquid’s surface, and convert it to antifreeze on the hydrometer graph. If there are balls show the numbers and colors that the force is flowing, check the instructions.
If the coolant is not dirty, lower the hose end of the hydrometer into the radiator filler neck. Slowly squeeze and release the rubber bladder above the hydrometer to draw coolant into the tester.
To find out how much to add, multiply the amount of coolant your car can hold by the percentage of concentrated coolant you want to get. For example, if you want the cooling system to be 50% concentrated, multiply 0.50 x 12 to get a volume of 6 liters.
