I have a most unusual Austin-Healey: It NEVER overheats, even at highway speeds on a hot summer day, thanks at least in part to an alloy Wizard radiator, performance water pump, and D. Welch alloy head. Engine was gone through and rebuilt from the new steel crankcase and con rods on up. Yet, despite trying both the 160 and 180-degree F thermostats available from Moss and others (modern disc type), it runs too cool on a cool morning, even at 50 to 60 degrees F.
Aside from covering part of the grille (which a photo of Donald Healey in the prototype Healey 100 at Jabbeke shows was done back then!), might the original type sleeved/bellows thermostat work better? Thanks in advance for your thoughts!
