Cooling - Controlling water temperature

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 pipes when ever it was doing anything other than a steady 70 miles an hour, over-heating eventually caused through water loss. Perhaps some deductions can be made from the following…

There are a number of elements involved in controlling water temperature. Some confusion over what to sort first when over-heating occurs leads to wasted time and money, and possibly terminal engine damage. Maximum power is usually generated from A-series engines at 70 – 75 degrees C (160 to 170 degrees F). The main problem with this on a road car is the oil’s unlikely to get hot enough for maximum performance – the results outlined previously.

I have been monitoring radiators and their development since the late 1960’s because they were and still can be a problem when tuning cars.

The front brakes are standard Cooper 'S' 71/2" variety with the standard drums on the rear, with the assistance of a servo the rear regulator valve has been left out of the system and the brakes work very well. As the weight of the second engine amounts to the equivalent of two 11 1/2 stone passengers. Rear cooling is taken care of using a 1300 radiator mounted in the standard position. The heater take offs are connected to a 19 row oil cooler.

In 1988, a humble 1973 Mini 1000 was minding its own business somewhere in London, when along came a young Mini freak called Jason King, who wanted to change it for ever, and make it famous.

Jason persuaded the owner to take £450 for the car, and then proceeded to throw £12,000 worth of presents at it for the next 3 years. Every minute of Jason’s spare time was spent working on his new car and every minute of his working time was spent looking for spares.
