Best Cooling Fan?

[vivapete3]

Hi, I want to replace the standard fan in my 1971 HC Viva Saloon,(1256cc), I like the Revotec Cooling Kit Fan, has anyone fitted one of these fans, and are these fans robust enough to work alone, so I can remove the standard Cooling fan? Any advice would be welcome, cheers, vivapete3

If you are looking for better cooling just flush your system out and/ or fit one of my recored rads - if you don't want to waste the BHP on driving the fan fit a pump and viscous fan

Hi Fred, thanx for reply, will flush the rad, not sure how a viscous fan does not waste BHP, main reason for changing to electric cooling fan is to save on fuel (hopefully) and boost the engine power output + a fellow member stated recently the 1256 engine was over cooled with the convential fan set up, cheers vivapete3

If a standard fan is over cooling I'd suggest the thermostat has probably been removed

The comment was mine but I certainly dont run the Viva without a thermostat - its a convertible and needs a decent heater too much! Back when we bought it nearly 40 years ago, when they were in common everyday use, HCs were renown for 'mayonnaise' - oil water emulsion in the rocker area due to running too cool. Ours had a thermostatic controller and only switched itself on in heavy stop start traffic. Later HCs with the viscous fans should be better I guess.

Yes thanx Mike re your comments, as far as I know my 71 HC has a thermostat fitted, just thought the engine would run more efficiently using a Revotec fan only, cheers vivapete3.
