Royal Purple Purple Ice Radiator Coolant

Frequently Asked Questions

Why Use Royal Purple? See PDF Below

Can I use Purple Ice in my new radiator? Purple Ice should not be used in new radiators until anti-freeze has been cycled through the system.

Can Purple Ice® be used with Dex-Cool® anti-freeze?
Yes. Purple Ice® is fully compatible with both Dex-Cool® type coolants (pinkish - orange) and the more common ethylene glycol (green dye).

What water / anti-freeze concentration is recommended when using Purple Ice®?
Purple Ice® may be added to any anti-freeze / water concentration; however, testing has shown higher water concentrations yield greater cooling benefits. While Purple Ice® does contain corrosion inhibitors as well as lubricants to compensate for a lower anti-freeze / water concentration, Royal Purple® recommends a minimum of 20 percent anti-freeze concentration be used in street driven vehicles because Purple Ice® has no effect on the boiling and / or freezing point of water.

How much Purple Ice® do I need to add to my cooling system?
When using Purple Ice® with an anti-freeze / water concentration, Royal Purple recommends adding 1 ounce of Purple Ice® per quart of cooling system capacity. For straight water (racing) applications, Royal Purple® recommends adding 1.5 ounces of Purple Ice® per quart of cooling system capacity.

Will adding too much Purple Ice® harm my cooling system?
No. A higher concentration of Purple Ice® than recommended won't offer any additional cooling benefit nor will it have any adverse effects on the engine or cooling system.

Can Purple Ice® be used in diesel engines?
Yes. Purple Ice® may used in diesel engines for improved heat transfer as well as reduced cavitation.

Specifications

Reduces Coolant Temperatures

Extensive testing confirms Purple Ice™ reduces coolant temperatures better than comparable products while providing extra corrosion protection. For example, the average operating temperature of a 350 c.i.d. V8 engine (equipped with 160° thermostat) when dyno-tested with different coolants are:

A. Standard Mix of water and antifreeze - 228 Degrees Fahrenheit

B. 50/50 water / antifreeze mix with Purple Ice - 222  Degrees Fahrenheit

C. Straight water (no corrosion protection) - 220 Degrees Fahrenheit

D. Water with Purple Ice added - 200 Degrees Fahrenheit

Additional Features

	Royal Purple Purple Ice Radiator Coolant: Purple Ice is formulated to reduce the surface tension of the coolant, which improves heat transfer through the cooling system while providing additional protection against rust, corrosion and erosion. Purple Ice prevents the formation of scale deposits in the radiator for optimum coolant flow and lubricates the seals of the water pump. It is ideal for use in straight water racing applications or in antifreeze / water mixtures
	Purple Ice Case QTY:12 (16-ounce bottles): Purple Ice is compatible with traditional ethylene glycol antifreeze (green) and GM Dex-Cool antifreeze coolants. Purple Ice should not be used in new radiators until anti-freeze has been cycled through the system. Extensive testing confirms Purple Ice reduces coolant temperatures better than comparable products while providing extra corrosion protection.
