Star-Cool Premium Synthetic PG Engine Coolant - 64 OZ (033264)

It is better than engine ice is all I can say. I was really impressed and blown away by how this product performs. I made sure I flushed the radiator 3x by running 50/50 water and vinegar mixture and flushing with distilled water til it is clear.l, then fill the coolant. This is one of best coolant we have ever used and we have used everything. We have also switched out the vehicles we have in Asia where it gets to 40c / 104F sitting in traffic for 2 hours. 4 years since and no scaling or corrossion. The lavramon machine was clear. We change every 2 years.

I had a leak in my heater core and this good stuff kept the leak at bay. It didn't stop it but it sure slowed it down. Plus, I emptied the old coolant and filled 2 gals of this mixed with distilled water (from the dehumidifier of course) because everyone bought all the distilled water at Target during the pandemic. Who needs all that distilled water? What are you doing with it? Using it for the airline you own? Anyway this stuff doesn't have that refrigerant odor and doesn't give you that strange headache with nightmares of being trapped in a freezer. Of course some people love that antifreeze perfume, so, my apologies to all those that take delight in that toxic musk. Besides being irritating, I find it brings back memories of changing water pumps on the side of the road in real winter weather. It awakens in me flashbacks to blown head gaskets and the acrid stench of boiling motor oil. So, God bless all of you that created this painless (and non toxic) substitute for nasty old antifreeze. And the extra genius of throwing magic stuff into the mix to help seal the leaks. Oh, and lets not forget about lowering the temperature of the engine. I almost forgot. You've heard the reviews of those nutty BMW people with their blinking headlights and secret club of Bavarian flying machines. I wish I had this stuff for a Cadillac that just ran way too hot. Still, I got 450K out of that 4.5L machine. True and funny. Anyway, enough about Cadillacs, now that I have my luxurious Dodge Caravan, I can enjoy low temps, slower leaks and that lovely, lovely, lack of odor. The price on this stuff fluctuates so don't jump too fast. Keep your wits about you and remember that frugality can be a good quality too.

Great ready to use coolant. Wish they sold it in a concentrated form, other than that it's my new go-to coolant for all 8 of my motorcycles. Boil point is lower than glycol but higher than water, non-corrosive, and compatible with other coolants. Very happy with it.

So I have a 2009 Toyota tacoma that was stalling on me while driving and noticed my regular coolant in the resevor was going low frequently so I figured could be a head gasket issue so I starting researching for something that can help and found this product. Let me tell you that I was amazed as it fixed my issue without spending thousands of dollars for a head gasket repair job.

Works great keeps your engine running a lot cooler helped my 2018 raptor 700r a lot

Particularly liked the longevity feature of this product!

Very good coolant so I ordered 4 more gallons for my truck and don't but that Evans waterless coolant its bad news

This is a superb product. It won't mess up your computer by running cooler, rather it maintains a very stable, ideal temp for the engine and components!
