Ive been chasing a coolant leak. Finally got a pressure tester and found a leak where these hoses connect to the engine. It appears the gasket has failed

First time really digging into this car and want to ask yall question before i do

Not a part I can buy at autozone so can I purchase the gasket from the dealer?

Has anyone replaced before? Any recommendations and what torque spec did you use when tightening the hose connector down

2007 Murano

Edited pic to clarify which two hoses I am talking about

Updating as I find info. Gasket is available at autozone. Its called a water bypass gasket
