4600 draining coolant

Bill Mack · Aug 9, 2020

I have to remove the lower radiator hose from my 4600. I'm not sure the best way to drain the coolant. Any advice is appreciated.

There is one on lower left in radiator and block is below inj pump or carb. Not much left since pulled lower hose.

Thanks. I haven't actually pulled the lower hose yet.

In the "small but interesting details department" ...
This is a replacement radiator that was on a tractor I parted out.
It has a small indentation where the drain cock would go but no drain cock.
Note what brand it is.

Original equipment 30 series radiators have no drain cocks. Removing the lower hose and draining the radiator are combined in one simple, messy operation.

It doesn't have to be a messy operation. Drain the block at the conventional location. Remove lower hose at the water pump and bend it down into a bucket. 90% of the radiator is now empty without spilling a drop. If the radiator needs to come out anyways, take it out with the hose. In fact, that's usually how I did it even if the radiator did have a drain cock.
