ive been running a Stant 180*, never had any issues. i went with the most expensive one advance sells (still cheap), rather than the $2 one lol

 

Your intercooler is definately going to reduce the efficiency of your cooling setup.

I had to go with loud-*** Spal fans and a bigger radiator/oil cooler on my car in texas. that solved my overheating in traffic issues. Still got quite hot at the track tho... (240+!)

 

duct your radiator, it will cool then. My stock 1.6 would overheat in traffic until I dropped the coolant:water ratio.

 

Today I had good success with fresh coolant (~3L actual coolant) and a bottle of water wetter. My cruising temps dropped ~3C to 92-93C and idle sits at 95C down from 97C. This is still without using the heater or having any ducting as I'm uneasy about changing the car's appearance to add an extractor and am too lazy to setup proper ducting.

As I said before prior to the fan mod, reroute and new coolant mix, I was seeing consistent 102C with the heater on full blast, all temps in 20-25C ambient.
