Forgot to check last night, so I searched the forum this morning. Found it.

It was in your post in this thread http://www.the370z.com/intake-exhaus...hermostat.html :p

The link to buy it in your post doesn't work anymore, but here's one that does from the same website.

I just checked thermostats for both the G and Z at my parts warehouses here at work and both say they are 180 degree.

??

The one in the link says 170. Maybe it was different for 2008?

The ones I showed were Gates and Motorad, and for 09 model years. I can't imagine they'd be different 09-13, but IDK. Let me check somewhere else real quick.

Ok I cant legally disclose my provider, but my manual says OE opening temps are Nissan 370Z: 170 degrees; Infiniti G37 Coupe: 180 degrees.

That's the exact opposite of what's been posted here for ages. Very odd.


The one I bought was OEM Infiniti for a 2008 and 170 degrees, but maybe the website was wrong. It wouldn't be the first time.

I would expect my "industrial strength" service manual to be more accurate lol! The website could easily be wrong.

I would hope so. Looking at that website, the 20110 370 thermostats are 180 degrees.

Maybe they've just got it backwards, but that doesn't explain how everybody here's been wrong since 2009.

Just checked all years for both and still the same, Z 170; G 180, and thats all body styles/models too.

And this is all manufacturer provided data. There is an error somewhere obviously, whether from the manufacturer or from the many parts houses.

Very weird. Factory service manuals all show a 170 degree thermostat for the Zs. Why have we been wrong for so long?

If all the info has been coming from the interwebz, thats probably why. I chase down mislabeled and misrepresented parts almost everyday, its very very very stupidly common.

So to get this back on topic, DE, you don't need a thermostat.

The Z1 Urethane mounts are really good. I have them in my car, motor and trans. My car has a slight vibration at times but nothing too bad.

If you end up going that route you shouldnt have to worry about them ever tearing again.

where do i get one of these? sounds like a fun read/refrence book :P
