The type and change interval for antifreeze has me in my usual state of indicision, severly confused.
Before the one brand was having cavitation or block casting problems I'd never heard of special antifreeze or additives. The mechanics at work did not seem to be updated either and some of them drove diesel trucks. My Kubota maual never mentioned it.
I did know that the antifreeze should be changed at 2-3 year intervals. Now the time has come to change antifreeze in the tractor, one car and the diesel truck. We have a reverse osmosis system so that water will be used for the dilution. Normally I've gone with a 50% mix.
Now for the question. What type of antifreeze and mix should I be using. Temperatures seen may be down to -40 centigrade on the truck?
All comments will be appreciated.
Thanks
Egon
