Use a refractometer to check antifreeze coolant concentration. The correct strength antifreeze coolant is important, hydrometers are often not very accurate tool to check the ratios.

This is a really GREAT demonstration of how to test antifreeze using the floating balls and the better tool. Some of the stuff on YT is total crap and you make it easy to understand. If you are inside a shop or its a little dark, the screen is black and you need light to make it work (just a tip).

You are welcome, John. The refractometer in the video is just a cheapo that I bought on eBay. A friend who worked in medical labs said it would do the job.

I just bought a specific gravity type antifreeze gage. It said my car is good for -20 degrees F, wife's car did not indicate at all - the pointer just hung straight down. Daughter's car same thing. Took the cars to a mechanic friend who pulled out his Bausch & Laum refractometer and it said all the cars were good to -10 to -15 degrees. So thank you for this excellent video. Now I know what to do. And thanks for no background music! I can actually hear you speaking clearly, unlike so many other videos.

Most modern cars will require a 50/50 mix so 50% of distilled water and adding 50% of the right oe coolant concentrate, so check the cars Oe coolant specs, plus if you live in a really hot place around the world, change and flush you coolant completely after every 2 years even through they say it will last 5 years IMHO, that way you know its good, but also by using a re factomter for checking glyco and inhibitor test strips is the best way to check how good is you radiator coolant in your car, the refractometer only test the glyco levels and not the inhibitors in the coolant, which test strips do both and are a lot cheaper, but the same meter checks other things as well, as you can see on the scale on the viewing lens. :) sedo

FYI it seems like the orange Mopar MS 9769 HOAT coolant and the regular flouscent yellow mixes with any type of coolant from Durex have the same 50/50 mix temperature range ratings of -34°f to 265° f !!!!

I'm happy with the upgrade, way better than a hydrometer. I have a friend who worked in a medical testing lab (old school when they used a refractometers to test urine), she said the cheap one should be just fine for antifreeze/coolant testing. BTW - One of these days I am going to get around to up grading the camera to get rid of the black bars. Your suggestion has not been forgotten.

@Ronbo765 5 жыл бұрын

TY. If you use a smartphone, then it should have the proper wide screen video format.

@Know-How-Now 5 жыл бұрын

Part of the problem is the logistics of mounting the camera. I've made a custom mount for short range & have a tripod. Eventually, I'll get around to upgrading and working out the new mounts. I'm very detailed oriented & hate to do crappy work, that equals slow but steady output. lol.

Good vid is the refractometer actually reading coolant concentration?

@Know-How-Now 3 жыл бұрын

To my best knowledge that's how the instrument works, though the science behind it is a bit above my pay grade. I use mine to make sure I that I have the correct mix of distilled water/coolant.
