I'm still = debating a bit about installing the monster cooling fan that I have.=20 In the air, on cold winter days at modest power settings (like cruise), the coolant temp can drop down to 150F = which is a bit on the cool side. =20 =3D=3D=3D> That was exactly what I needed to know. Thanks. If having = only 150F in cruise was my only problem, I think I'd consider myself pretty lucky = :-)=20 Not saying don't use a thermostat, just saying I tried twice and for whatever reason (poor cooling system design?) did not have success. = Almost cooked my engine twice, so decided it was not worth messing with. =3D=3D=3D> Fair enough. Thanks again. Rusty
