"I have just finished fitting two Davies Craig 9in fans and a single Davies Craig control system. The fans fit fairly neatly under the radiator top reservoir ledge, and controls fit under the heater air inlet duct at top of pic. I set the control to kick in at about 193dF (water thermo is 180dF sliding sleeve type) and went for a hilly drive. All was very stable. Fan cuts in and cools the water down about 3dF and then cuts out after about 45sec, as per spec.

At bottom of pic you can see the Tudor plastic atmos overflow bottle. Its cradle is connected to a small bracket bolted to the radiator mounting flange. Water flowed in and out of bottle. Now need a really hot day"!
