Coolant Testers

Coolant Testers

Coolant testers are essential tools for automotive mechanics to diagnose and repair cooling systems. They measure the coolant's specific gravity, which indicates its condition and helps mechanics identify leaks. Coolant testers also measure the coolant's pH level, which helps mechanics identify corrosion and other problems.

Types of Coolant Testers

There are two main types of coolant testers: electronic and hydrometers. Electronic coolant testers are more accurate than hydrometers, but they are also more expensive. Hydrometers are less accurate, but they are also less expensive and easier to use.

How to Use a Coolant Tester

To use a coolant tester, follow these steps:

1. Remove the radiator cap and fill the tester with coolant.
2. Squeeze the tester's bulb to create a vacuum.
3. Release the bulb and read the coolant's specific gravity and pH level.
