A number of people have asked me about the electric fans that I have on my C which, unlike most aftermarket fans seen on the C are the same size (often there is a large one and a smaller one). Back in 2009, one of my engine mounts failed which led to my fan becoming acquainted with my radiator.
I looked at an original replacement but decided to go for electric fans. On the recommendation of Jeremy at Surrey Sports & Classics (http://www.surreysportsandclassics.com/) I went for twin Kenlowes (2000 Series). They fit perfectly across a standard C radiator as the photos show.
My notes from the time “Picked up Kenlowes from Jeremy. Easy instructions to understand. Only issue was that I must fit a relay (says that in instructions) and although it works without a cowl, they recommend also not fitting the top piece because if I do it is not supported by the (absent) cowl and it will bend the first time I lean on it. Decided wanted to fit Kenlowe’s in a way that meant I could put it all back to the original in the future. Managed this with only impact being small hole drilled to mount the relay and the “spreading” of the radiator fins on the front for the Kenlowe mounting system. Fitted seal inside top hose (difficult to get to seal) and also put Thermostat sensor just beside this using the top piece mounting hole / bolt. Checked wiring by bypassing the thermostat switch and it worked fine. 2.5ltr antifreeze and topped up with water. Kenlowes work fine (small leak but tightened top hose). Cable tied all cables to make it look neat (carefully measured these before fitting end electrical connections and used blue wire stripped out of 1.5mm mains cable for correct blue to blue wire connection) . Tightened fan belt. Cap on top of engine is not pressurised (correct). Fan set to cut in at ½ way between C and N plus 2 of the smaller notches on the dial which equates to ½ way between N and H on the temp gauge inside the car. Locked dial on thermostat (one washer underneath) ” “Investigating why the car got so hot. I was doing about 25 mph and it just got hotter and hotter. NOTICED THAT THE FAN IS NOT ROTATING THE RIGHT WAY. THE CORRECT WAY IS CLOCKWISE AS LOOKING FROM THE ENGINE TO THE RADIATOR (LABEL ONTOP SAYS THAT). BUT I HAD CONNECTED BLUE TO POWER AND BLACK TO EARTH. So at 25 mph the forward effect of the car cancelled out the fan “push” effect so it just got hotter and hotter. Also the fan probably doesn’t move much air when spinning the wrong way. Kenlowe instructions say that you can swap leads over to make the motor spin the other way so did this. Blue to earth and Black to Positive. Checked this by putting small amount of chalk on one of the blades and it now does rotate clockwise (more difficult to tell than it sounds) and works very well. Kept same setting as this was the right kick in temperature.” .
