Question , with picture

[OlFerguson]

Anyone have an idea what this could be ? I’ve pulled the water pump and it seems to be ok. I’m not sure where this is Comin from . Machine is an m100. I was underneath the tractor when I took this

Sorry can't tell what we are looking at?
If it's coolant, was coolant coming out of the weep hole in the bottom of the water pump?
look for rust or calcification at the weep hole.

I've looked at that picture 4 times it's just making me dizzy!

water generally only flows downhill... so follow the stream 'up' ??
if you can't get your head in there, take a zillion pictures......
ONE of them HAS to show where the source is....

sorry for a piss poor quality picture . I put the pressure tester on it and the leak is coming from between the water pump and the engine block . I inserted a new seal between the 2, lined it up and torqued it to spec. Why would it still leak?? Thx

Very likely it's the seals in the water pump.

But there is a whole lot of connections going on right there, water pump, thermostat flange, frost plugs, hose connections.

it leaks from the 2 bottom bolts that hold the pump to the block . Might be easier and more expensive just to replace it. Machine has 1860 hrs

I'd put a new water pump on it, as it sounds like it may have warped or cracked.
Oh and one maybe quick thing, some of the bolts on Kubota heads go into the water jackets, so I always put thread sealer on them when I install.

I agree on the thread sealer. I usually Permatex those.

I got the new pump installed. Checked all my coolant lines and pressure tested it and held over a minute. Everything is running good again . As always appreciate this forum for the help you all provide .
