It’s antifreeze. It’s for water cooled engines. It’s needed here in the cold climates. Read more

Perfect replacement for expensive OEM, this is spec for ford

Enrique VargasJanuary 26, 2025✓ Verified purchase

Right before the winter came, I went for a complete drain and fill of coolant, lately it's been very cold and I noticed each week the coolant was less and less, however I didn't see any spillage at all. I noticed that the coolant that was used from the place I went to "jiffy lube" used a lighter orange color compared to the Ford golden orange. I found myself topping the coolant off each week. That's never happened before, so I knew it had to be the coolant that was used. I then took it to a mechanic that I knew after ordering this coolant and he let me know that using the correct coolant is so important, that it has to be Ford (or vehicle ) Spec. He said that one of the signs is that it takes longer to heat up the vehicle, which was happening to me. Once I changed it to this coolant, the car heated up right away, it's been three weeks and I haven't had to do any topping off, no evaporation at all. The best part is that this is indeed a premium coolant at a major value for the money spent. I never realized that making sure your coolant is to the exact spec of what the manufacturer requires is that important. I'm happy I realized that now before something going wrong with the engine.

It's a very effective product. No weird smell.

My 5 star review is for how quickly I received this. I was stranded on the highway and AAA ordered it for me and brought it to me. They took me to a motel nearby, they had it delivered to the motel, drove me back to my pickup and watched me drive away. Amazon is my hero. Read more
