I’ve run it about 30 minutes at idle in a garage at about 60*. Dead on at 185*. Much cooler than my previous but I know there’s loads of capacity here. The lower tank is cool to the touch while the upper is dang hot....185ish I’d say. Lol. I used a 50/50 Preston’s antifreeze mix good to 265 and -30 by the hydrometer.
The air flow through this is fantastic and I know the shroud makes a huge difference.
I’m loving the Cold Case so far....and it looks great too.
