## Overview

Rislone Hy-per Cool Super Coolant is a synthetic, 16 oz. liquid additive designed to reduce engine temperatures by up to 25°F through advanced wetting agents that enhance heat transfer. It offers maximum corrosion protection for all metals in cooling systems, lubricates water pump seals, and is compatible with all antifreeze types and colors. Ideal for high-performance engines, motorsports, towing, and everyday vehicles, this USA-made formula ensures your engine runs cooler, quieter, and longer.

## Description

Rislone Hy-per Cool Super Coolant: High performance engines require coolant to transfer as much heat as possible. As cylinder head temperatures increase, so does the likelihood of detonation and power loss unless ignition timing is retarded. Under extreme conditions, this can also result in overheating and engine damage. Hy-Per Lube Super Coolant reduces the surface tension of coolant, allowing it to more deeply penetrate metal surfaces at critical heat transfer areas inside the engine and radiator. This results in more heat being transferred away from cylinder heads and a reduction in engine operating temperatures.

Review: Well worth the money. - This stuff works well. I use it in my Jeep Liberty 3.7, which keeps the temp down when driving on the beach,

I highly recommend this.

## Questions & Answers

**Q: Does anyone know if this coolant has any glycol or glucose in it?**
A: From what is listed on the Safety Data Sheet (SDS), there does not appear to be any glycol or glucose.  The SDS is on their website.

**Q: Anyone have any luck running this stuff in an older Jeep Cherokee? I have a 93 that overheats religiously even though everything's brand new.**
A: This is not an overheating preventative. It’s mostly for vehicles that do run a little hot on occasions! It helped me with my car that has headers and no AC keep temps a bit lower for cruising

**Q: can this product be used in marine engine**
A: Yes. !  A closed cooling system !  I run it in my Hino w4oc turbo diesel , the Hilton hyper lube coolant made for diesel engines.  Water & coolant only , the lake I keep my boat on never freezes and I run a engine room heater during the winter months for that reassurance of freezing, engines run nice n cool all year long

**Q: I wonder if this will effect the usefulness of a head gasket sealer product such as Bars head gasket sealer? Wondering if it may inhibit the sealer fr**
A: No
