96001 Kool-It Supreme Coolant Treatment, 16 oz.

My car wasn't overheating. But the coolant has been in there for over 2 years. And I wanted to reduce the acidity level. Worked great

Great product.

If you have an O'Reilly Auto Parts near by. They sell this item for $9.99. Very upset that I'm paying more than in a retail store. Stop being so Greedy!!! The product works as described, just follow the directions and get some test strips to see if you added enough.

Works as well as the other small bottle brands, but the price is a deal killer as the green one is almost half the price. I was happy with its performance though.

As to the reduction in temp......... if your cooling system is working correctly your engine temperature will always come up to at least the temp of your thermostat, Most are either 180 or 195 for them to open and flow coolant to the radiator....... no matter how efficient your coolant is....... Your engine will always reach the temp of the t-stat, as it should. Where this product comes into play is when your system cannot keep the temp at the thermostat and starts to overheat with the thermostat open and flowing coolant to the radiator for various reasons. ]Always Flush your system and replace all coolant prior to using this product. Inspect and or replace the Thermostat and make certain there are no leaks or clogs and the radiator fins are clear of debris, make certain fans and fan clutches are working. The product works as advertised........ But does not fix damaged systems.

I can’t say whether this actually helped my 2019 Ford Ranger truck, but the dye in the additive turned my Ford yellow coolant a kind of orange color. Now if you say what’s the big deal, the deal is that I have an extended powertrain warranty and having a non Ford coolant could be grounds for denying a warranty claim if something ever happened with the engine. Previous to this Ford used the orange coolant which isn’t compatible with these newer motors. Why dye the additive at all? My Subaru uses blue coolant, I can’t imagine what that would look like in the overflow bottle. I’m in process of siphoning out the bottle and replacing it with the factory coolant so that it looks like the OEM fluid. Thanks a lot Lubegard.

I was having some problems with electrolysis in my pickup truck which caused the heater core to clog up.I would have to flush the heater core periodically because of this.I grounded my radiator to the frame and added this product to the coolant and guess what it worked like a charm.I now use this product in all of my vehicles.

Can't go wrong with lubeguard. Definitely notice a temperature difference in the antifreeze.

Use it once yearly mixed with my ford oem coolant on my mustang. Keeps it running cooler and longer. 500k+ and counting. Its good to use as preventative maintenance!

Verwende und fahre diesen Kühlzusatz in all meinen Fahrzeugen und bin absolut zufrieden!

Ich konnte keine sichtbaren und/oder messbaren Veränderungen feststellen, weder positiv noch negativ. Ich bezweifele den Sinn eines Kaufs., vergleichbar zu den Ölzusätzen desselben Hauses. Ich würde basierend auf meiner Erfahrung immer Zusätze von MATHY vorziehen.

Schnelle Lieferung...toll :)
