Tom – Having originally been shipped to Algeria, this car never had a heater. Consequently the frozen apple that was on my dashboard when I left Cambridge only defrosted when I got south of Bordeaux!
Fitting a heater for the high altitude sections has been on my mind for a while though the original Smiths Heaters are famously bad. You can buy an original looking Clayton Heater but they don’t put out much heat, are quite expensive and don’t fit very well in a left hand drive. I have therefore gone for a much cheeper Kit car heater that uses the cooling water in the same way as the smiths heater but gives out a lot more heat. It even has a pleasing Steam Punk look to it.
