I just got my PTS aluminum radiator installed and was wondering if any of you are using any special additive due to the aluminum. Any comments or opinions would be welcome. Thanks Happy Memorial Day!
RMI-25 is a liquid additive, it helps clean the radiator to prevent rust and mineral build-up. It also contains a ph stabilizer to help balance the acid/alkaline levels of your antifreeze.(if you run antifreeze). It also will help dissolve any scale build-up and mineral build-up you may have in your radiator. You only need like 8 oz. per 5 gallons of water. It's supposed to help clean the thermostat, water pump and your heater valve etc. etc. etc.
This link will give you the info you need to know.
The web site price states "shipping is included" for RMI, this is NOT correct as the webmaster has been out of town, and has not yet updated this for 8 oz. bottles. The quart size is no longer available.
