The work on the cooling system continues, as we tackle the common problem of a rusted header tank. In this episode, we'll look at the internal and external design features of the original tanks, compare them to aftermarket units, and then restore some originals tanks - inside and out. We'll also look at the original otter switch that activates the cooling fan.

The Series 1 E-Types used a steel header tank, and these were one of the weak links of the E-Type design as they tended to rust away very quickly. This car was built in August of 1966, and taken off the road sometime in 1971... IN those first 5 years, the header tank was repaired multiple times, and may have eventually led to the end of this car's life on the road.

The header tank is located between the engine and radiator - physically - but in reality, it's at the "end" of the system. Enjoy this in-depth look!
