B7410 Coolant Leak

[BKWOOD]

Tractor leaking coolant. Thought it was thermostat gasket. Installed new one. Still leaking. Not having a repair manual with parts breakdown I am not sure what the housing for thermostat is connected to. The leak is in this area but cannot pinpoint. Could also be the lower radiator hose but not obvious. Going to order new hose but before I have to disassemble to install hose are there other possible locations for the leak? It is definitely in this area.

Spray dye penetrant developer onto the area and it’ll be first to get wet at the actual leak. (or some old timers would use baby powder or flour).

Before you reload the "Parts Cannon"

It might be a good idea to try a cheap "coolant system pressure tester" like this, and an "inspection mirror".

BUT, make sure it will fit your machine before you buy it.

You can see all the parts here: https://apps.kubotausa.com/illustrated-parts/

This is the thermostat housing. there is a gasket to the block.

Below that is the water pump.
Check the hose clamps, a loose one can drip.
Run a paper towel under the pulley if it comes up wet the water pump is bad, get a new one.

He was somewhat being a wise acre...
You can use baby powder or flour to find the leak as it will stick to wet areas.
