Royal Purple 01600 Purple Ice Super-Coolant Radiator Additive - 12 oz.

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

I use this in all my cars. It does lower the operating temperature as stated. Cheaper on Amazon than your local parts store

My 4.7 V8 Jeep was starting to run a little warm. Did a complete coolant flush, added this stuff with new coolant. Tested at idle with my cooling fans turned off, no ac, my V8 stays below 205 without any radiator fan on. Don't expect it to work if your water pump is going out or you have a thermostat not opening up, replace those first. Anyone who doubts this stuff look up Project Farms YouTube video on these products.

This coolant performs well and helps maintain stable engine temperatures under regular use. It feels like a quality product that supports consistent cooling performance. It mixes and circulates without issues in compatible systems. It’s a bit more expensive than standard options, but the performance feels solid. Overall, it’s a dependable coolant for maintaining engine health.

There was no apparent change in operating temps for the 2004 Toyota Sequoia (4.7L), but then again, Toyota Gauges (at least in the Sequoia's) were and probably remain notorious for being 'wonky'. i.e. its oil pressure gauge typically reads low, until it doesn't, then it does again. The analog gas gauge is also a delight, usually showing the gas level with reasonable accuracy, but other times appearing to be empty, complete with the illuminated idiot light, even after a recent fill up, when you know darn well there is plenty of gas in it. With such suspect gauges, the heat reduction on her vehicle is inconclusive. I'd have needed a thermal reader with her vehicle to compare the before and after. Even so, the RP Ice provides lubrication for the thermostat and water pump (though most pumps are sealed now), plus its anti-corrosion elements are beneficial. I had added some distilled water to the 50/50 mix radiator fluid for the ideal ratio for better performance of the RP Ice additive in both vehicles that maintains an appropriate freeze protection for our location. I've since read that using purified water in radiators is better than using distilled. It may be that distilled water pulls minerals from the internal metal surface areas into the radiator fluid? Regardless, I used what I had on hand (distilled). However, my 1992 (350 CID/ 5.7L) Chevy Cube Van's analog gas gauge indicated a drop of at least a 10° F from it's previous normal operating temperature, perhaps up towards 15° F temperature drop after being left to idle up to operating temperatures twice, then IRL driving about and on a cross country trip towing a 14' cargo trailer.

Made his purpose

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!

Average - never noticed a difference in temp.

Buen producto. No debe usarse completo, sino por onza en cada litro si tienes mezcla 50/50 anticongelante ( si no, no te sorprendas que haga espuma; además que no sirve de nada ponerle una mayor proporción a lo que indica Royal Purple). Por otro lado, no esperes una baja de temperatura, sino mayor capacidad de "reducción" de temperatura del sistema de anticongelante, y la confiabilidad de un aditivio que alargará la capacidad de flujo del anticongelante y la vida útil de tus mangueras. A veces buen precio: 350 pesos.

Works great!! We use it to help cool our derby engines!

Amazing product, had to try but it works, superb quality, does what it says.tried on my nissan juke 1.6 turbo and cools much better dropping the temperature much more quickly than just normal coolant. Temperature between 84 degrees and 87 degrees.

A must add to your cooling system. Keeps the temperature down in summer heat. My car runs cool.
