Antifreeze coolant specifications

[REBrueckner]

Following is broad understandable technical information I finally found regarding different antifreeze formulations and specifications for them. The following WEBA corp site reflects one maker of antifreeze additives; PENRAY is another. This WEBA discussion explains what ATA RTP 329 spec we need for Detroit Diesels actually means:low silicate!!!

Article 3 at this website provides details on antifreeze formulations for conventional (like powercool) and also newer OAT and HOAT formulations.

I decided to go with conventional formulation Detroit Diesel Powercool since its about the same price I can get Fleetcharge, another well know brand. Both of these are conventional formulations and can be rejuvenated via SCA's (supplementary coolant additives) instead of complete flushing and changing of engine antifreeze. Test strips determine when SCA's are required.

Here in Vancouver BC we are fortunate in having soft water, the PH is almost perfect and the powercool seems to last forever, also, when the boat is washed, no spots, it's great. Then when I go down to Florida to my Hatt, spots everywhere, get out the chamois.!!!!

Forever is a long time. make sure your test strips are mot expired.

Stopping spots and fighting coolant cavation is a different challange.

does anyone here run a coolant filter/conditioner? i had original vintage 1970 filters but the insert is not available so i removed them. it seems to be a good idea assumably doing away with manually testing (less frequent anyway) and adding of SCA as the filter time releases the SCAs. i run powercool and am content with it. i also use distilled water when filling.
thanks
