Lubegard 96001 Kool-It Supreme Coolant Treatment, 16 oz.

It’s important to add some form of water wetter to your engine coolant in order to break the surface tension of the water; allowing it to flow more smoothly and efficiently.

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.

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.

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 found a data sheet that showed a comparison of a lot of products from a lot of respectable brand names. this one came out on top. I was kind of shocked I figured it would be the red line or some other brand but lube guard has proven once again that they know something about something. as far as automotive additives this is one of the few brands that I think you can trust about everything they make. what really got me trusting them is their warranties outrageous claims with their products. The chart showed about what it would drop the temperature and it did about that. not everyone's vehicle is going to be in the same condition so the results May vary. this is one product I highly recommend

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.

All lubegard products are great.

It seems to cool a little better when driving but sitting at idle it jumps back mainly to normal, not a big deal because I have a 160' degree stat, but got it for cleaning and keeping corrosion out of the system on a fresh flush.
