Rislone Hy-per Cool Super Coolant, 16 oz.

This stuff works well. I use it in my Jeep Liberty 3.7, which keeps the temp down when driving on the beach,

Great stuff. It works. It's definitely not snake oil. I have been using this stuff since 1990. I pour it in all my cars. It keeps the car running much cooler and quieter. It keeps the radiator from rusting out and in fact it protects the water pump. It's a lubricant and a protector. I highly recommend this.

Works exactly as described. Helps keep engine running cooler under heavy use

This stuff definitely works it cools my engine 50 degrees cooler I use it in my ford diesels n haying tractors

Works but. Didn`t notice any temp differences.

THIS REALLY WORKS, MY SONS OLD JEEP KEPT GETTING HOT, PUT THIS IN HIS ANTI FREEZE AND RUNS COOL ALL THE TIME NOW, THANK U! GREAT DEAL!

I put this in my 2000 Jeep XJ these are notorious for running HOT! This product dropped the temp by 4 or 5 degrees. Doesnt sound like much but it is a help. Worth it in my opinion.

Works as described

Excellent product

Product was leaking

I can't say I notice a huge difference since using this product. My car wasn't overheating. I think this is a good preventative and good product to refresh older coolant. The corrosion inhibitors and surfactants can't hurt.

This stuff works. lowered the temp by 5 degrees and that can be critical on a hot day with a classic car.
