hey guys anyone got a z or coupe thermostat. if yes, how hard was the install? how are you liking it. for a whopping 20 bucks, im willing to give it a shot

 

Don't bother unless you want to screw around with trying to get all the air bubbles out of the cooling system after you do this. If you're looking for a way to lower cooling system temps, consider getting the OEM higher pressure radiator cap from a 300ZXTT. It will essentially do the same thing, but for cheaper and a lot less work.

 

where could i get one of those radiator caps?

 

I have one. Install was easy and I did not drain the system. I did have air bubbles but purging the system of air was easy with the plug. I bought an aftermarket 300zx TT radiator cap to go along with the 350z/coupe thermostat but the seal was really crappy and was leaking. Never went to Nissan to get an oem one.

 

Nissan dealership

 

Do you mean the Nismo thermostat? I thought the oem one was the same for all three cars.

 

The FSM shows the sedan to have a higher rated t-stat than the coupe and z, at least for 03-06. Different part numbers showing the different temps shows in the FAST catalog.

 

You should buy the Nismo, it is better. I see constant lower temps with it.

 

Wow, I didn't know that. I thought they were all the same.

 

I just got a thermostat from a g coupe (sport model). is this the same as the z?

 

Opening temp is on the thermostat, look for a Celsius rating.

 

oh cool, so it should say 170 right.

 

170c is pretty hot, it should say something in the 70s

 

I think he meant 170F?

 

The stamp is in Celsius. My mental calculator is broken. lol
