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'.

    Hold up, What happens when I fill my car's radiator with antifreeze more than distilled water? Yeah, the solution is simple, I can easily add plain distilled water, but I am very curious on what happens in this case.

    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.

    I have a bunch of question... I have rust in my radiator and its leaking at about 12 blade no's of the radiator and it was totalled to be weld... 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!

It was like -10 Celsius and I really was woried that my cars Block would crack,so much so I drove it hard to get it up to temperature and then let it sit thru the night...

    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.
