Product Description

Purple Ice is a high performance, synthetic, radiator coolant additive. It reduces engine heat by reducing the surface tension of the radiator fluids for improved heat transfer. Purple Ice fosters optimum coolant flow by helping to prevent formation of scale deposits in the radiator. It also lubricates the water pump seals. Purple Ice should always be used in conjunction with antifreeze in regions where freezing temperatures occur. Purple Ice is recommended for any water/glycol pressurized cooling system, including those using the traditional green silicate based glycols or the newer OAT or HOAT based glycols.

1.0 out of 5 stars CAUTION: NOT GOOD WITH ALUMINUM, November 1, 2010

I would not recommend running RP ICE with Aluminum engine or radiators with DISTILLED WATER.

This ONLY applies to DISTILLED WATER with out anti-freeze. RP ICE with distilled water is corrosive and will eat away at your aluminum engine parts.

I ran RP ICE with distilled water combo for max cooling for my track car. What happened was my heater core was corroded and started leaking from corrosion caused by this product.

Also what you will notice is if you get this product on aluminum parts, it will stain the metal white and cannot be wiped off. It also leaves a grey coating inside your radiator and piping.

I would recommend using Redline Water Wetter as an alternative. I get the same results with water wetter and it CAN be used with 100% distilled water with OUT anti freeze.

I am a BIG fan of RP products and PR ICE is the only product from them that i have had problems with.

If you run RP ICE with distilled and ANTI FREEZE, you will be ok. I would still recommend RL Water Wetter

This product I saw on the speed network and decided to try it on my K1500.
It works and lowered the radiator coolant temperature as advertised.
Bought it for my other two vehicles.
