07 350z thermostat
 

As of recent my car throws a P0128 thermostat code. The coolant temp gauge is acting funny, i.e. warming up then dropping below operating temp. On side note, the cabin heat is still functioning properly. I am going to replace the thermostat, but before proceeding I have a question.
Dose Nissan Part #21200-JK20A include the gasket and everything for a complete install, or do I need gasket maker and the thermostat housing?

Best regards,

thats just the thermo itself, with your vin i can tell you for sure but usually nissan makes it as difficult as they can haha. i would get the gasket though, it would be a pain to rip all that apart to replace a $2 gasket just my 2 cents

Your help is much appreciated!
