Mikesbucketlistmack Posted April 12 Share Posted April 12 I'm contemplating changing the coolant conditioner on my 1981 R612. I've had the truck over 10 years and barely drive it 50 miles per year. It has only 65,000 miles on it. Do you think the coolant conditioner should be changed and if I take it off while the truck is off will I get a bath of antifreeze ? Thanks !
