I read in LRO this month that putting in a kenlow fan can save 10% on the fuel bill. I like the sound of this.  :D

Do I HAVE to fit a kenlow fan or could I go to a scrap yard and get a beefy fan from there? If so what else do I need to do to make it kick in and out etc and is it an easy job?

Also, would I really notice a difference in less fuel?

crazymac:
Fuel saving?? not convinced.

I took my viscous fan off more than 3 years ago and have replaced it with nothing! Thats right, nothing. My temp guage sits around the 1st quarter even when towing.

I do have aircon fitted (although the rad and all other gubbings have been removed leaving just the aircon fans!!!)

The fans have a switch built in that turns them on when the temp rises above 3/4 but that has only ever happened once on a lane day!

Disco-Ron:
I fitted two small leccy fans on my old 200, along with an x switch that switched each one at different temps....

diggerdog36:
Anything that runs off the engine will use extra fuel, so a viscous fan will use more than a lecky fan, you could use any lecky fan (big enough) off a mondeo, vectra etc, and use an X-Eng switch they are the best on the market, everything else WILL die after a few months!!!

This was number 1 saving in LRO this month!

I am not sure about no fans at all. I have seen the temp guage rise to max when towing once as the rad was old and grimey. I think I would be a bit unsure about and constantly looking at the guage more than I do now!!

I have air con fans but aircon is broken. How easy is it to wire in these fans then and do they do the same job as a fan the other side of the rad?
