Reliable Coolant From a Trusted Brand
Good quality coolant that comes pre-mixed and ready to use. Easy for topping off or doing a full coolant change. Zerex is a trusted brand and this works exactly as expected.

Cools well.
After changing the coolant in the radiator three times and replacing the old coolant with this Zerex, engine is running 5 degrees F cooler at all times and with less temperature fluctuations.

It is the right coolant for our car
We have an older car. My wife doesn't handle change very well. She likes her car so we keep it running as best we can. We developed a problem with coolant levels. I'm leaning towards a loose reservoir tank cap rather than a leak. No evidence on the floor of anything leaking. Have you tried to buy coolant recently? They used to tell you what was in it - no more. Lots of brands for sale all about the same price. But no info on the ingredients. Look at the color they say - well some is orange, some is green, some is somewhere in between. This one had a label that had some key information that matched the owner's manual. We added some. In a day or so we should know if we have a leak or a resolution. Keeping out fingers crossed.

Im not too sure how you're suppose to review coolant to be honest. Because if its working, and generally most coolants do work in Canada, then there's really nothing to say. Its not like one companies formulation is really causing a dramatic difference compared to another. So in general all i can say is that this coolant works. It works like the OEM branded 50/50 mixed stuff at canadian tire. Obviously I'm comparing the coolants that are rated for the same applications. In my case this is going into a 2003 wrangler. So i suppose this review is just to tell you that this item specifically, gets the high praise of "It works so you can buy it". But if imma be real honest with y'all. Just get the cheaper stuff. As long as its got the correct rating that your service manual calls for, even the cheapest stuff will do the same thing. Its coolant.
