[Healeys] Aluminum Radiator

[Steven Kingsbury]

Kees,
The temp sensor is in the radiator, top, passenger side. I'm pretty sure my
thermostat is not functioning correctly and a new one is on order. As soon as
I have it installed and we get some more hot weather, I'll report back on my
findings of driving up hill in the heat.
