With my turbo, I can grill steaks with the under hood temps but the engine runs at 186-190. I'm running a North aluminum radiator with about 80% distilled water, 20% antifreeze and a bottle f Purple Ice. I also have a Lincoln MK VIII electric fan pulling the air through two tranny coolers, a P/S cooler and the Intercooler. If that bitch can run cool, anything can. Try throwing wome Redline Water Wetter of rPurple Ice into the coolant mix. It does help.
