It provides superior corrosion and electrolysis protection compatible with all coolant types, while lubricating water pump seals to extend system life. Designed for vehicle-specific fitment, it’s ideal for maintaining peak engine efficiency and preventing overheating in all driving conditions. ## Description 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. desertcart.com Royal Purple's Purple Ice is a high performance radiator conditioner. Its advanced 2-in-1 corrosion inhibitor and wetting agent provides year-round defense against corrosion. Purple Ice also reduces the surface tension of the radiator coolant to help reduce engine temperatures.Reduces Coolant TemperaturesExtensive testing confirms Purple Ice reduces coolant temperatures better than comparable products while providing extra corrosion protection. Performance AdvantagesUp to 22°F Reduction of Coolant Temperature--Reduces surface tension of a coolant allowing more heat to transfer outside the radiator resulting in more horsepowerMaximum Protection--Reduces hot spots in the engine and cylinder heads, reducing the possibility of engine failureCleans and Extends Equipment Life--Helps prevent overheating, keeps the system clean and extends the life of the water pumpSuperior Corrosion Protection--Enhanced aluminum protection that combats corrosion, electrolysis and erosionCompatible--Provides complete protection in straight water or coolant/anti-freeze mixes and safe for track useDirections: Shake Well Before Using Make sure cooling system works properly and is free of blockage and corrosion. Bottled, filtered drinking water is recommended. Distilled water not recommended, unless mixed with 50% antifreeze.Use one (1) oz per quart of coolant with 50/50 mix or two (2) oz per quart of coolant with straight water. Replace annually or every 30,000 miles, whichever comes first.IMPORTANT NOTES: Purple Ice does NOT provide freeze protection. Follow manufacturer recommendations when antifreeze is required. Royal Purple recommends that you drain and flush your system if you’ve used another brand of coolant additive. Purple Ice will NOT correct any pre-existing mechanical deficiencies of a cooling system.Distilled water should not be used in straight water-cooling systems with aluminum radiators. Filtered drinking water or tap water is recommended for such cooling systems.Purple Ice--FAQsIs Purple Ice compatible with other cooling system additives?Purple Ice should not be used with other heat-transfer or cooling enhancing products or “water wetters”. If such a product has been used in the cooling system, the system should be drained and flushed before using Purple Ice.Purple Ice is compatible with cooling system additives intended to stop or slow leaks. Please note that such stop-leak products often typically put a coating on the interior surfaces of the cooling system, so the effects of Purple Ice may be diminished.Is Purple Ice compatible with anti-freeze in my car?Purple Ice is compatible with all current OEM/factory and major brand automotive anti-freeze. This includes traditional green ethylene glycols, as well as OAT/HOAT antifreezes (e.g. DexCool; Ford and Chrysler orange, gold, pink; European and Japanese OEM red, pink, etc.).What water/anti-freeze concentration is recommended when using Purple Ice?Purple Ice may be added to any anti-freeze/water mix; 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 antifreeze 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 antifreeze/water mix, Royal Purple recommends adding 1 ounce of Purple Ice per quart of cooling system capacity. For straight water (racing) applications, Royal Purple recommends adding 2 ounces of Purple Ice per quart of cooling system capacity.How often should I add Purple Ice to my radiator?When used with antifreeze, Purple Ice should be added once a year or every 30,000 miles, whichever comes first, in order to maintain proper performance. When using Purple Ice in a cooling system running straight water, Purple Ice should be added once a year or every 15,000 miles, whichever comes first.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 be used in diesel engines for improved heat transfer as well as reduced cavitation. Review: Seems to keep water pump seals healthy! - Well many will call this snake oil , but I’ve used this for years to prevent my vehicle coolants from causing overheating and to protect my water pumps! Review: Seems like it makes the cooling system a lot more efficient - Okay, it's not going to fix a leak or stop overheating issue but i used it on both of my ford rangers 96/04 it works great it definitely helps cooling system run smoother, overall and work more efficient and seems too smooth everything out, it's great as a pervative measurement To add ## Features - OPTIMIZES PROTECTION - Prevents erosion and electrolysis - Compatible with all coolants types - Contains lubricants to protect the water pump - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BRGAJ2 | | Best Sellers Rank | #7,875 in Automotive ( See Top 100 in Automotive ) #40 in Antifreezes & Coolants | | Brand | Royal Purple | | Brand Name | Royal Purple | | Customer Reviews | 4.5 out of 5 stars 1,891 Reviews | | Global Trade Identification Number | 00641330016004 | | Item Type Name | Coolant | | Item Weight | 0.8 Pounds | | Liquid Volume | 1 Quarts | | Manufacturer | Royal Purple | | Model Number | ROY01600 | | Number of Items | 1 | | Part Number | 01600 | | UPC | 641330016004 | | Unit Count | 12.0 Fluid Ounces | | Warranty Description | No | ## Product Details - **Brand:** Royal Purple - **Global Trade Identification Number:** 00641330016004 - **Item Weight:** 0.8 Pounds - **Liquid Volume:** 1 Quarts - **Manufacturer:** Royal Purple ## Images ![01600 Purple Ice Super-Coolant Radiator Additive - 12 oz. - Image 1](https://m.media-amazon.com/images/I/71pPLJPYeHL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: how about a cadi norhtstar engine?** A: Yes.

Over the years it appears that there's some build-up that just will not flush out of the engine. This only affects the car when the Houston temperatures get into the mid to upper nineties. The car does not overheat but it runs hotter than I would like. I tried the purple ice, Which coincidentally I installed during a multi day period Of nearly 100 deg. temperature days. To my amazement my engine temperatures were lower (even when compared to the gauge reading during the lower 90 deg. temperature days). There are people out there who believe that your car engine thermostat will just adjust to compensate for any improvement the product may cause thus rendering purple ice ineffective. However think about this logically, the reason a person would add this is because during periods where your thermostat is completely open and is unable to provide any more cooling your temperature may still increase.... and this product is able to help disperse that increased heat in some way by its chemical formulation... again, Your thermostat is fully open and your engine temperatures continue to climb non the less....adding this can help Another way that this product indicates its effectiveness is that my engine takes longer to reach operating temperature by about triple the time. So this product is absolutely doing something to help the coolant release heat. And for those that think that there is a problem with driving your car for 15 to 20 extra minutes before it reaches operating temperature asked them to phone their friends in Wisconsin Minnesota Alaska in other extreme cold States and they will find that this is normal for a few months a year with no adverse effect on your car engine reliability....
