sprint cooling fan

[foxface]

Hi I am going to fit electric cooling after recently changing the water pump and the standard fan not working. I have read about other members fitting the revotec electric fan with the control switch in the top hose and manual override. Can anyone advise on the fan belt size to drive the alternator and will I need to remove the radiator to fit the fan.
Regards Terry.

Hi Terry, I've been working with James on here on his lekky fan and the fan-belt for use with an electric fan looks like ...

i.e. GCB10737
You can fit / remove the Kenlowe version without removing the rad; I wasn't keen on the fixings of one lekky rad; we read about with tie-wraps through the rad; core. You don't really want to place any extra stress on the rad. The Kenlowe is better as it uses separate side bars.

Fan belt is a 7280 GATES XL 10A0710 that should be available at any motor factors.

32mm Revotec controller is brilliant, just set it to start the fan 10-12 degrees above the temperature of your thermostat. The fan must go off before the thermostat closes! If it's working correctly the fan will not be on when driving on the open road, only when stopped or driving slowly in heavy traffic.

Another trick is to wire the relay that comes with the kit into a fused feed that is live when the ignition is off. That way the fan continues to run on a hot day to cool the radiator and engine bay after you've stopped the engine. You can walk away and the controller turns the fan off automatically when the temperature gets down.

A manual override switch is always a good safety measure.

The Kenlowe is better as it uses separate side bars.

They used to come with fixing bars Tony, many years ago. The last 4-5 I've fitted had the through-rad ties.

The through rad ties everyone is supplying now are not exactly cable ties, have a smaller circular profile and seem to work OK.

I've recently done some research cos I needed an electric fan for the Dolomega and whilst I like the Revotec, it seems a trifle pricey to me at around £77 for the fan and a complete kit coming in at close to £150. So i've opted for a British made 12" Aeroline fan for £40 widely available on ebay and a hose mounted thermostatic switch from Stoney Racing (also on ebay) for £25. It's available in a wide range of hose sizes and temp ranges. I've already fitted several of these to customer cars (and the Carledo) no problems so far.

Of course, i've had to supply my own relay and wire it up, but it's not rocket science and relays are only a couple of quid.
