I’m going to address the cooling systems on my new 91 350SD, and the 91 300D that I’ve had a few months.
Would like to clean and flush the cooling systems before I take them both over to John Deere Cool Gard II. This can be a slow process over many months as the cars get driven and I have time. I’m thinking while it’s still warm to do a water flush and use a cleaning agent. Any recommendation? These are iron block aluminum head engines so I’m a bit sensitive to that.
Any thoughts?
