It was well over 100C in traffic, which would eventually cool down when I got moving. The car didn’t overheat, but I did hear coolant boiling in the radiator hose after I finished the drive. While the...

It is only at idle they only rely on pulling air through...
Last September, the electric fan on the E-Type stopped working. This is a particular problem in the E-Type as there is no mechanical fan. At the time I assumed the coolant temperature sensor had failed. It would seem that many people have trouble with these sensors.
