Незамерзайка для отопления. Ядовитая или "полезная". Какую брать?

How a heating system is destroyed by a bad antifreeze. A natural experiment. How long does an antifreeze last, how to extend its service life. Propylene glycol and ethylene glycol - more expensive does not mean better. How to check the condition of the coolant at home. We make a decision - to change the coolant or let it work a little longer. How not to run into a fake when choosing a coolant Why the coolant must be diluted, even when it is already diluted. Why you can not dilute more than allowed. You can not mix coolants under any circumstances A coolant based on glycerin should be avoided at all costs. Thanks for watching!
