I thought OEM KA thermo is hotter, but I might be wrong

SR stock is 76 deg C which is like 168 F.

I wasn't sure so I got the FSM off the shelf to check before I posted. I had heard that they are the exact same part from Nissan from people as KA guys use the SR performance Themos with lower temps(Nismo, Billion, ect.).

At atmospheric pressure. You have to remember you have the radiator cap boosting the pressure in the system to 11-14psi. Effectively boosting the boiling point. Putting a 300zx 16psi cap will raise the boiling point even more. Also, why when you are over heating you don't want to relieve the pressure. Water will flash boil in the head. Happened to a member this week an hour after he sold the car to some idiot.

OE fan runs low at 203, high at 212. Normal range is 180-190. Thermo opens at 170.

Check for blockage and air pockets.
