Aluminum radiator installed - overcooling :(
So, I've installed an eBay aluminum radiator with slim fans and a new thermostat in my '00 and now it's taking forever to get to an operating temperature.
It is not a consistent behavior either. Sometimes it takes about 5-10 minutes to get to operating temperature and sometimes it can be 30+ minutes. It's worse when driving at freeway speeds.
Anyone has any clues? Car is stock.

^ Agree with the above.
It has to be thermostat related. When the motor is cool the radiator shouldn't be seeing any significant flow and it should warm up in a few minutes. My stock gauge shows normal temp by the time it hits 150 degrees so if that's where you're getting the reading from it's way cold.
Stock NB thermostat is 195, NA is 180 which is preferable IMO. I'd buy a new 180 degree thermostat and more than likely that's going to fix the problem.

whats the temperature rating? when the stat first opens?
the 1.6L NA is actually:
Initial-opening temperature
Main: 86.5-89.5°C (188-193°F)
Sub: 83.5-86.5°C (182-188°F)
Full-open temperature: 100°C (212°F)
I haven't seen what the 1.8L NAs stat looks like, im sure its similar. the part numbers are different, but it looks to be a dual-stat as well.
but yeah, the NB runs hotter.

I'm curious why the na 1.8's use the 180* (according to you guys) and the nb uses the 195*?
Does anyone know?
I heard someone say "emissions" before, but why would the nb require to run hotter to achieve the same emissions numbers as the na? Or is the nb supposed to run "cleaner"?
