Screwed up

[whitetop]

Off topic Question here. I have a NH farm tractor and changed the antifreeze today. I always use distilled water/antifreeze mix but for some reason today I forgot and used regular tap water even though I had 2 gallons of distiled water on the workbench. Tractor has a aluminum radiator.
\
Should I flush it out and replace? I put about 60 hours pr year on the tractor and replace the antifreeze every 2 years.


I plan on keeping this tractor forever and don't want corrosion problems or blocking of rad passages..

BTW our water is very limey and full of chemicals...more than other locals.

Or should I just run it and change it out next year.

Thanks
