[Healeys] Over heating Healey's

[Kees Oudesluijs]

Why not fit a thermostatic switch in the top tank or hose to control the 
fan. Kicking in at ca. 200 -210°F and kicking out at about 185°F should 
do the trick. Use an adaptor with to accommodate the majority of thermal 
switches, in EU it is M22 if I remember correctly. There are thousands 
of them to choose from.

Keep the manual override switch though.
