That's about as good as a Semi will cool especially here in the altitude pulling these long mountain passes. The system works well.and uses the stock overflow bottle.
Is the Pentastar fan plug and play on let’s say a 2009? I have a 5.7 2010 truck Hemi with the JSS kit. Using the fan clutch and 18” fan works fine. The fan is about 3/4”-1” from the radiator. My first radiator, Northern, sprung a leak after a little over a year.

I used a TJ coolant bottle on the pax side. May switch out to a 3x10” recirc bottle from summit
