The number one requirement of any cooling system is that it should be effective. By that I mean keeping the engine operating at its optimum working temperature for best overall performance, aligned to acceptable durability. At one time this was consi... read more

When I was young (TV shows in black-and-white only, and so on) vehicle radiators were much taller than they were wide. Designed to make maximum use of a natural phenomenon called the ‘thermo-syphon effect’, when the coolant was introduced... read more
