What type of Coolant?

I strongly beleive the 180F thermostat from Nissan is far and above the chain store thermostats you can buy. Stant, I think, is not even in the ballpark when it comes to quality compared to Nissan.

I have read this too. The aftermarket options don’t have nearly as large an opening as the OEM variant. 
 

I’m running a 280 radiator, two electric fans, and a full shroud. Inside is some distilled water with water wetter. No issues since I added the shroud!
