Coolant t-stats

[C Schomer]

The NAPA 370-180 stat did fine last weekend on hard pulls (towing) in the mtns. The smaller port isn't the big issue I feared and cycling is better than the old 3934373 Cummins stat (DC #05014568AA). Temp went to 215 at near WOT, 4th gear, 26-2700 rpm, 1200 egt, 30 lbs boost and 90 degrees ambient. That's similar to the Cummins stat, when it was still working right. The NAPA stat was $8. 95. Craig
