[Healeys] Over heating Healey's

[Tom Felts]

why not install a 6 bladed fan?  My BJ8 has never overheated after adding one and that was a lot of years ago.tom

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.

During
 the past 3 weeks since the rebuilt engine started, I have
 been running the engine for 20 min at a time.  The temp
 would slowly climb to almost 200 degrees, so I would shut it
 off. Finally, I got help from my friend wiring the pusher
 radiator fan I installed with the radiator. We wired the fan
 to the altenator with a relay and  fused the toggle switch
 to the spare on the fuse block on the engine firewall. 
 Started the engine and ran it for 30 min at mostly idle with
 a few min up to 3500.  It held a constant 180 degrees. It is
 currently 80 Degrees in SW Florida and your skin will burn
 if you are in the sun.  That should give anyone the answer
 “how to modify my Healey to be able to drive it in hot
 temperatures and in traffic”  My engine before rebuild would
 only overheat in hot summer weather in Chicago or in Florida
 when driving in Stop and Go Traffic or under 40 mph.  With
 the new shovel in front of the radiator directing air into
 the radiator, I expect that I do not have to turn on the fan
 at lower speeds that 40 mph.  Will know more as soon as I
 can get the car off the jack stands. Bob
