So it seems that after sitting for 10 years + there was actually some biological growth in my water jacket and radiator. I had vinegar in there for probably better than a month which I hope killed it and removed some of the gunk. However looking in the top of my radiator it still looks like the tubes have some clog in them. My question is how can I clean out the radiator? Also looking in my water jacket it appears I have a fair amount of scale and dead vegetation. How can I clean that out? I'm leaning toward running this with out the water pump as Henry intended, but to do this I know the coolant system must be in good shape.

Tom the best way to clean out the cooling system water jackets is to remove the cylinder head and start from there. There will be different opinions for sure but to do a thorough job removing the head and carefully using a 1/4" inch drill to carefully drill out the congested 1/4" holes in the head and in the block is the sure way to clean out those passages. This is important for good water circulation.
While the head is off you can use a screwdriver, a speedometer cable in a hand drill or something similar to get the scale out of the block and head. After nearly 90 years there is a LOT of scale that can build up.

If your not in a big hurry, letting the block and head dry out and then using compressed air will help remove the scale. I found flushing the block does help but doesn't always get the heavy scale out.
Opinions will vary.

I put a 30 inch gas range in my shop it will easily heat to 600 or more degrees' depending on self clean or not. It turns the water jackets and oil soaked iron to powder. Its easy to see why J and M uses a commercial version for there work. Without scale and oil the block has to be blasted but the media does not load so it lasts longer. You do need an exhaust fan for the smoke from the oven. A-T block just fits and many other T parts as well with out lots of gas use.

My brain is dead from watching to much election results. My post above was rebuilding---If my intent was to clean the water jackets then I would cap off the inlet put the outlet back on and fill with vinegar for a dew days and use johns post to see how much crud comes out. Bet its a bunch!

If you soak it in acetone you will remove all the paint, but you will also remove a vast majority of any organic compounds, grease, and oil that might be in there. Then flush it out with plenty of water.

Paul is also correct in using a self cleaning oven.

Mark, you should have your own auto repair show on MPR. By the way, by your first video, you must not be married?

I have my heads BACKED. They bake them at a high temp. and it cooks the rust loose. They come back looking like they were just cast. Don
