How to TEST Your Coolant for the Winter (Before Major DAMAGE is Done)

Learn how to test your antifreeze, and how to change your coolant to make sure it is protecting your car's engine and cooling system properly. In this video I cover what how to properly test your coolant and top off your radiator so it is a 50/50 mix that way your car wont overheat and your engine block wont freeze or corrode.

Also if the heat in your car is weak or you dont have heat, in this video I will show you how to bleed the air out of the cooling system so you can get heat Coolant is 50% antifreeze and 50% distilled water. And no, freeze plugs are not going to save your engine block from freezing and cracking every time.

    @Krischen Price do note that that some people get away with calling some things the wrong way, and it in fact becomes their identity, that this man calls this thing this way and not that way. Christopher is also one of them, with his identity becoming him always calling water as 'wooder'.

    Bad experience with that head gasket crud on a Jaguar I bought. It clogs the spots of where the gasket had cracked/corroded from, but this stuff leaves a residue through out the system, like cholesterol in an artery, it builds. This overheated the Jag I had. No wonder the guy sold it to me for 900. We know you know how to change a head gasket. Stop being lazy and change it, because you’ll just added a future headache/heartbreak. Besides it ‘better safe than sorry’, so you go ChrisFix that correctly or someone is going to have a beautiful Jag just sitting on the lot for a while. 🚗🚙🛻🚖🚘🚕🚙🚖🚘🚗🚙🚕🏎

    You would (ironically) have a lower freezing point, much less heat transfer ability, and any additives they put in wouldn't work because it requires wooder to suspend the molecules!

    Being someone from Malaysia, specifically a mere 4.4 degrees north of the equator where we never go below 24°C or 75°F, I always find 'antifreeze' confusing and it's to be something needed in cold places only, turns out it's a 50/50 mix and has higher boiling temp. Glad to learn that! Also, I always use hose wooder for my wipers since it doesn't freeze here. Not something I'd recommend but for people where I'm from it's pretty normal.

    Hello Chris, I have a question. You say at 10:40 that there is no problem if you come a little over the maximum line with the cooling fluid. But when I use the Spill Proof Funnel, I am actually very much above the maximum line. Actually, the liquid is then filled all the way to the top. Do I have to take liquid out until it is at the maximum line? Greetings from Germany. PS: Cool that you now have a German car :)

  • Tristan Gray

    Sorry if this has been asked already, but I doubt it has because I can't find the info anywhere. I'd like to test my coolant, but I'm finding it difficult to understand why everybody is checking the fluid not from the radiator itself, but from the reservoir. From my understanding from what I have read, the expansion reservoir does not actually circulate coolant through the system, it only acts as to 1.) not allow overflow from spilling onto the ground, 2.) does not allow air to enter the system, and 3.) maintains 100% fill in the system if there is a leak, or other issues, such as burn off, or whatever. If what I'm reading is correct, the only time the liquid in the overflow tank could actually be sucked into the system is possible during the expanding / contracting process, or if there is a leak / burn off of the liquid within the circulatory system. So, if people are checking the reservoir for proper concentration of the liquid within the system, isn't that completely incorrect? Please learn me here... I'm dumbfounded and probably wrong.

When I'm buying aftermarket radiator, it stated on the box "DON'T USE COOLANT" So, i used filtered water as my radiator coolant... My question is 1. Why the warning for not using coolant?? 2. If i wanted to use antifreeze and antirust, it is gonna effect the radiator? 3. My radiator still have rusty water, is it normal?

    Do keep in mind that distilled water does transfer heat away from components better than straight antifreeze, so if you live in hotter climates that does not see freezing temperatures you can mix more distilled water than antifreeze such as what was in the Jaguar for more effective cooling. Other than that, great video Chris!

    Nice video Chris. You could take testing of coolant a little further though. This method only tells you that the coolant is strong enough to stop your car from overheating or the coolant freezing it doesn't tell you if the corrosion inhibitors are still doing their job. To do this use a multimeter. Set it to millivolts scale DC or 20vDC .Put the negative probe on a good ground and the positive probe in to the Antifreeze. The reading should be below 200 millivolts or 0.2v. Anything higher means that the inhibitors are failing and there is an electrolytic reaction taking place. Give it a go.
