I'm looking for ways to approach this. The overflow tank looks pretty nasty inside so I'm going to remove and power wash that out. I have no idea when green was added. The cooling system works fine. It had a waterpump replaced recently. The owner said he thought it leaked green coolant when the water pump failed but he wasn't sure. Highly doubt some one converted it correctly, it's had a few owners.
I would rather not stir up too much with an aggressive flush. I figured first things first, I'll drain the coolant and try to peek inside the radiator and see how it looks. Then run water through it, leave it filled with water and drive it. Then see how it looks. Maybe throw a little vinegar in on the 2nd water refill if the drained water looks dirty?
Also, I knew it had mismatched coolant in it when I bought it. It has a couple other issues too that let me get it for a great price.
