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 still like to drive one of my older cars regularly. 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.... Sorry for being so long.. this product works

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.

Used this on my 2019 ram with cummins diesel. Runs a little cooler i may put a second one in. I have used this on my 2005 corvette and I noticed a 10 degree drop

Does what it says it does. Royal purple makes good products.

Recommended by dealer service easy to add to vehicle

Average - never noticed a difference in temp.

I use this product all the time in my racecars to protect all aluminum parts. Motor plates, heads and waterpump mainly

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.
