The cooling system in the Mini has used the same basic style radiator since it's begining in 1959 up until the introduction of the twin point injected cars when the radiator was moved to the front of the car.

In the past, fitting an oil cooler was mandatory once an engine had been even slightly uprated. The main cause for this was the quality of Motor Oils available at that time. If the oil temperatures exceeded a specific point, then engine failure was almost guaranteed.

The introduction of the Cooper S proved to be a testing time for the Mini's systems, but conveniently provide a guideline as to what the standard cooling system was capable of - that used on the 'S' was marginal to say the least! It wasn't uncommon for many S's to spew water from their overflow p

Very few understand just what the cooling system does and how it does it, and that incompatibility between the cooling system's capability and an upgraded engine can spell disaster for the new engine.
