What types of automotive coolant testers does ToolSource offer?

ToolSource offers a variety of coolant testers, including hydrometers, refractometers, and test strips. These tools are designed to measure the freeze point and boiling point protection of your coolant. We carry 63 different coolant testers from brands like Waekon Industries, Mityvac, and Assenmacher Specialty Tools.

How do I choose the right coolant tester for my needs?

Consider the level of accuracy you require and the type of coolant you'll be testing. Hydrometers are a cost-effective option for general use, while refractometers offer more precise readings. Test strips provide a quick and easy way to check coolant condition, but may not be as accurate.

Can these coolant testers be used on all types of antifreeze?

Many coolant testers are designed to work with a variety of antifreeze types, including ethylene glycol and propylene glycol based coolants. However, it's important to check the product specifications to ensure compatibility with your specific coolant type. Some testers, like those from Motorad / Stant, may be designed for specific coolant formulations.

What is the purpose of using a coolant tester?

A coolant tester allows you to determine the freeze point protection of your engine coolant, preventing damage from freezing temperatures. It also helps you assess the coolant's boiling point protection, preventing overheating. Regular testing ensures your cooling system is functioning optimally and protects your engine from corrosion and damage.

How often should I test my vehicle's coolant?

It's generally recommended to test your coolant at least once a year, or more frequently if you suspect a problem. Factors like climate, driving conditions, and the age of your coolant can affect its performance. Using a coolant tester from brands like Thexton Mfg Co or OTC Tools and Equipment can help you monitor coolant condition and prevent costly repairs.

What is the difference between a hydrometer and a refractometer coolant tester?

A hydrometer measures the specific gravity of the coolant to determine its freeze point protection, using a floating scale. A refractometer measures the refractive index of the coolant, which is more precise and less affected by temperature variations. Refractometers, such as some models from Robinair, generally offer a more accurate reading.

Do you carry coolant testers that can detect coolant leaks?

While most coolant testers focus on freeze point and boiling point protection, some specialized tools can help detect coolant leaks. These tools often involve pressure testing the cooling system to identify leaks. Check the specific product descriptions to see if a particular coolant tester offers leak detection capabilities.

Are there any specific tools needed to use these coolant testers effectively?

Most coolant testers are relatively simple to use and don't require specialized tools. However, you may need a clean container to collect a coolant sample and a rag to wipe off the tester. For more advanced testing or leak detection, you might need additional equipment like pressure testers or UV dye kits, some of which are available from Kent-Moore.

The Thexton 106 Cold-Chek Anti-Freeze Tester is a professional-grade, disc-type tool designed for accurate and reliable coolant analysis in automotive and industrial applications. This large, durable tester provides comprehensive readings on both hot and cold coolant, ensuring technicians can quickly assess antifreeze protection levels and overall system efficiency. Its clear, convex barrel and magnified discs allow for easy and precise interpretation of results, critical for efficient workshop diagnostics.

Key Features

Professional-Grade Accuracy: Delivers precise readings at all coolant temperatures, hot or cold.
Easy-to-Read Disc System: Features magnified discs within a clear SAN plastic barrel for clear, unambiguous readings.
Dual Scale Readings: Protection scale is clearly marked in both Celsius and Fahrenheit for broad applicability.
Overprotection Indicator: A unique 6th disc alerts technicians to over-concentration of antifreeze, indicating potential loss of cooling efficiency.
Durable Construction: Built with a robust one-piece bulb and a long-lasting neoprene dip tube for reliable, repeated use.

Applications

The Thexton 106 Cold-Chek Anti-Freeze Tester is an essential tool for automotive technicians and industrial mechanics. It is designed for use with Ethylene Glycol-based coolants, including common formulations such as Dex-Cool®, Prestone®, and Zerex®. This tester efficiently determines the optimal 50/50 antifreeze-to-water mixture, which typically provides protection down to -34°F, and identifies when excessive antifreeze concentration (over 70%) may reduce cooling and corrosion effectiveness.
