Coolant leak in 1996 400L

I have a great running 400 sportsman with a slow coolant leak near hose insertion into the block. I cannot diagnose this further.
Is this a "big" problem? Common problem??
Any suggestions are appreciated.

try a few ounces of radiator stop-leak,not the whole bottle ,though as your cooling system only holds about 2 qts.

ixnay on the op-leakstay. Is that the original hose? Now nearly 15 years old? Hoses deteriorate with age.

Thank you all.
I will flip it on its tail and change the hose. It runs way to well for it to be major.
(wishfull thinking!)
