Hi all.
I'm about to do coolant drain/fill, and would like to change thermostat as well.
I looked up on courtseynissanparts.com and some other parts site to get the part number but it only shows the part number for thermostat itself, but not the housing.

FSM suggests to replace the thermostat with housing all together, not to disassemble thermostat from its housing.
I searched this site and g35driver.com but no luck.
Anyone know the part number for thermostat with housing?

If not, is it easy to take off thermostat from its housing and install new one?
does it require any special tools to do it?

Thermostat gasket :13050-31U00
Thermostat :21200-4W01B

Thanks guys.

 

I believe the picture on the Courtesy site is a little deceptive. The main diagram shows the assembly as part 21200...



It describes that as Thermostat Assembly. When you click on the link for item 21200, it takes you to the details which shows a thermostat for 2003-2006 and the housing for 2007+. I'm sure if you order the one for 2003-2006 you'll still get the full assembly.

 

thank you for your time and effort on response dave.
I contacted the courtesy nissan and they said I would get the full assembly (thermostat and housing) with the thermostat part#21200-4W01B.

It's funny there website shows actual picture of thermostat only with that part number but it's actually the whole assembly unit.

Thanks again dave and hope this short thread becomes helpful for someone in the future.

 

This is a good thread that shows the delete of the oil cooler and use of the HR 350z thermostat housing.....
