: RE: [Healeys] Continuing the thermostat thread
Now I almost can unequivocally say that the gauge is faulty or at the very
least sticks. I doubt that any Healey owner on this list hasn't shut the
engine off at or near the 212 mark and not seen it continue to rise after
shut down..
I would still recommend that you buy or borrow an infra red laser aim-able
and compare the temp of the hoses, head, thermostat housing, top and bottom
of the radiator, etc. with what we now know to be accurate reading (up to
212F)gauge when everything is up to temp and running.
If it's not steaming over and the bottom of the radiator is oh, ten degrees
cooler than the top then you can relax and be happy. Efficient running is at
or above 190F. anyway.
The gauges are typically designed for most cars to run roughly in the
middle. I think for cars that remained in England that was true, at the
time, given the more moderate speeds and ambient temps. Here in the States
with multiple climate zones it's not unusual for a Healey to run on the
right side of normal...but not truly too hot.
