After installing AC I found that the engine was no longer cooled sufficiently for the Australian summer climate. The reasons were two fold - firstly a condenser was now in front of the radiator and the original twin electric fans mounted in a cowl, were positioned at least 6 inches away from the condenser and were not forcing air through the condenser and radiator - it was too easy for the air to go around these obstructions. A large electric fan was added to the rear of the radiator, this improved the situation, but the engine cooling was still marginal at best on 30+ degree days.

The original, radiator, cowl and fans were removed and a new radiator and twin fan assembly was fabricated. The condenser was moved forward and this new assembly was mounted behind the condenser, so effectively the fan were sandwiched between the condenser and radiator. We found that an additional fan on the back of the radiator was still required, but this was effective in keeping the engine at the correct temperature even in hot weather.

It has since occurred to me that the AC performance may be improved by fitting a fan to the front of the condenser.
