thanx It is very new ( 2hrs and 30 miles around block ) It seems to overhaet if I drive it and then let it idle. The gauge goes up to 210 or so. I checked the coolent temp and got 207 with good thermometer. I got the pump with the 7" pully and large 4 blade fan and a 4core triple flow (US Rad) Desert Cooler from Patricks. I lowered the radiator 1 1/8" and the fan clearance is about 1/2". I pulled the new thermostat and replaced it after checking both on stove ( they were both spot on at 180. maybe your right and I need to break it in some more. Any advice on breakin? When it gets hot the oil press drops to 15-20 lbs at idle. I'm worried about that. It has 30W with zinc add. in it right now. Tom
