In my screenshot I just posted straight from their websiteI must have missed something, where was this said?
Interested to hear about what way it is not performing. From talking to the guy from CEM the supplier of the RMI25, one of the things he reiterated was that it is an active cleaning ingredient that is used up in the chemical process of converting rust scale into a less harmful ferric-phosphate compound that is then in the water rather than coating the block and reducing heat transfer. That means as the stuff cleans the block, the water will change colour, then you need to flush it out fill with clean water and add more RMI25. It should continue to keep the surfaces clean and not change the water colour for a longer period next time (obviously that depends on how dirty, corroded the motor was to start).In recent days testing, I will not be using RMI-25 in the foreseeable future. I'm not sure what has changed but it is not performing as previous.
Now currently on the quest for a suitable replacement.......
Will be interested in further reports after radiator removal and clean out and check of the core, I was going to go to this stuff after I fix my little leak peranently during which I'll drain and flush.My td42 has had nothing but RMI-25 for the last 170k. I have used this is more than 1 vehicle as well.
I was a big advocate for RMI-25.
On the weekend while testing, we lifted the thermostat housing.
The system is covered in a brown slime that is greasy to touch.
In that past 12 months I've dropped the coolant over 10 times.
Every time re-dosing with RMI.
This weekend will be a system flush and then radiator removal for cleaning.
Its less than $30 to do a TD42. RMI-25 for $35 does two coolant changes.I mention that 10 10ths in the first post and put the data sheet in post 19 (along with other data sheets), says it is OK for road use, but it is expensive.
