What should your antifreeze reading be?
A reading of . 4 volts or less means the coolant is good. Replace the coolant if the reading is higher than . 4 volts.
When testing coolant to get a more accurate result What temperature should the coolant be?
Best Temperature for Accurate Antifreeze Readings Antifreeze should be less than 120° Fahrenheit. Colder antifreeze does not have an affect on the rate or final color development. Antifreeze of 120°F is cool enough to be handled and the radiator cap is cool enough to remove from the radiator.
How do you read a hydrometer for antifreeze?
Ensure that the hydrometer is completely filled with coolant and note where the indicator points on the “freeze point” scale. The freeze point of the coolant should not be above minus 34 degrees Fahrenheit. If the reading shows a higher freeze point, you must have your cooling system flushed and refilled with coolant.

How do you test the coolant in an engine?
To test your coolant mixture, you’ll need to take a sample from your radiator or coolant reservoir, whichever’s easiest. Be sure to let your engine cool down before you remove your radiator or coolant reservoir cap. Once the engine is cool, open the cap and suck a sample of coolant into the test tube.
