B7200 running hot

That hose is a burp hose.
It keeps the block from trapping a bubble in it and causing a hot spot.
It was eliminated on later models with a redesign of the thermostat housing.

Haha - lots to be learned here. Thanks.

Before you toss your old radiator, you might consider taking it to a radiator shop to see what they can do for you. Mine got a pinhole leak in it a few years ago. I was surprised what an OEM rad cost back then. So I took it to my local shop and they repaired it for around $60. I haven't touched it since. They might have some tricks to flush yours free so you can reuse or keep as a spare....

That's all well and good if you can actually find a local radiator shop.

There is a local radiator repairer I went to once for something different - $2K to re-core. But that was quite a bit bigger - was a radiator out of an ex Australian army Unimog (my other tractor).

I will be keeping the old radiator, and nothing to lose by asking them for a price.
