How do you check the quality of coolant?
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.
How do you test for radiator stray current?
To test for stray/electric current, use an analogue voltmeter with sensitivity of 0.03 volts or a stray current detector by first placing the positive lead directly into the coolant (through the filler neck on the radiator), or in the overflow bottle (for a closed system), making sure that the terminal is not in …
How do you test coolant with a multimeter?
Here’s a quick way to check it. Begin with a cold engine. Remove the radiator cap and start the engine. Set your digital multimeter to DC volts at 20 volts or less. When the engine reaches operating temperature, insert the positive probe directly into the coolant.
What should the digital meter read for coolant?
If the digital meter reads .4 volts or less, your coolant is in good condition. If it’s greater than .4 volts, the electrolysis additives are exhausted, and you may be in the market for a new radiator, a water pump or a heater core in the future.
How to check the conductivity of the coolant?
If the conductivity is high, it’s time for a coolant flush and fill. Here’s a quick way to check it. Begin with a cold engine. Remove the radiator cap and start the engine. Set your digital multimeter to DC volts at 20 volts or less. When the engine reaches operating temperature, insert the positive probe directly into the coolant.
When to check coolant levels in your car?
Most people know to regularly check engine coolant levels in their car, but what some don’t realize is that coolant breaks down over time and eventually loses its ability to protect your engine and radiator. So for this DIY episode, Hagerty’s Randy Clouse walks you through how to test your coolant and on our 1969 Chevrolet Camaro SS.
Set your digital multimeter to DC volts at 20 volts or less. When the engine reaches operating temperature, insert the positive probe directly into the coolant. Rev the engine to 2,000 rpm and place the negative probe on the negative battery terminal. If the digital meter reads .4 volts or less, your coolant is in good condition.

How can I check the coolant level in my car?
Use a flashlight to look down into the radiator, and inspect the coolant level and condition. If the system does not have an overflow tank, the coolant level will be lower to allow for expansion when the engine it at operating temperature. Coolant should be a slightly transparent, and many colors are available.
