RMI-25 – other Frequently Asked Questions

How do I use RMI-25?

Very simply! Pour the recommended dose of RMI-25 into the radiator and run the engine. You may have to remove some coolant/antifreeze to allow the space for the required amount of RMI-25. Radiator draining and refilling are usually not required.

How quickly does RMI-25 work?

When added to coolant at the recommended dose rate, RMI-25 will clean dirty and corroded cooling systems in about 15 hours of normal operation.

How often do I check RMI-25 in my cooling system?

It’s important to test the pH level and if necessary, re-treat your cooling system with RMI-25 every 15,000 miles (24,000 Km) or 300 hours. pH levels should be set between 8.2 – 10. Test with pH strips. Add RMI-25 if acidic.

Can I add too much RMI-25 to Antifreeze?

If RMI-25 is added from time to time to ensure the correct pH level of the cooling system is maintained, the freeze point of the antifreeze may be affected by the dilution. It is recommended to check the freeze point during routine maintenance procedures.

Does RMI-25 extend cooling system longevity?

Yes! There is nothing you can get on the market today that does a better job of keeping the cooling system 100% efficient; extending the life of all system components, and reducing maintenance and repair costs than RMI-25.

How much RMI-25 do I use in racing applications?

When freezing protection is not needed, mix 32-64 fl oz of RMI-25 with distilled water, depending on cooling system capacity and engine horsepower.

Can I use RMI-25 with intercooling systems for superchargers?

Absolutely! RMI-25 works great, and will protect the whole intercooling system and it will run cooler. It’s recommended starting with 8 fl oz of RMI-25 and possibly more with bigger capacity cooling systems.

Does RMI-25 change my maintenance schedule on coolant?

Yes! Adding RMI-25 is like recycling or recharging the coolant without having to first drain it from the system and then refill the entire cooling system with expensive new coolant/antifreeze.

Is it OK to treat new coolant with RMI-25?

Yes! Remember, coolant has no cleaning action, and by using RMI-25, it gives you that extra edge, as well as all the other benefits that come with it.

I have a new vehicle. Is there any advantage to using RMI-25?

Yes! Adding RMI-25 to the cooling system of a new vehicle will provide greater protection against deposit buildup, will remove foundry rust and deposits, and promote much greater heat transfer from the metal engine components into the liquid coolant.

I don’t know how old my antifreeze is, what should I do?

In this situation, it is best to change it. Refill the cooling system with new antifreeze/coolant and add RMI-25 at the appropriate rate. If antifreeze is not required, use distilled or de-mineralized water and add RMI-25 at the appropriate rate.

Can I use RMI-25 with water only?

Yes! Be sure you use distilled or mineral free water mixed with RMI-25 in your cooling system. Using normal water is a huge No-No, as normal water usually contains a lot of minerals that rapidly accelerate the corrosion process within the cooling system.

Does RMI-25 clean so well it can create leaks in the system?

Sometimes. This may happen if the cooling system has been seriously neglected and is on the edge of failure.

Is RMI-25 safe to handle?

Yes, RMI-25 is NON-TOXIC, NON-HAZARDOUS and BIODEGRADABLE. RMI-25 is safe to use with all metals, plastics, hoses, and seals. It is compatible with all types of antifreeze/coolant solutions and metal-based stop leaks.

What are other uses for RMI-25?

RMI-25 can be used in heating systems that use hot water.
