Coolant Leak at coolant outlet

[markosider2]

Hi friends, It looks like I have a coolant leak on the passenger side of the engine, front of the engine. Picture is from behind passenger seat. There is a coolant hose coming out of this flange. I cannot seem to find this part online. Do I remove the flange and replace a gasket, or is it just a sealer, or is this some type of part that should be replaced? Thanks in advance
