hi there just a quick question i wana fit electric fans to my fourtrak instead of the viscas fan but would it be best to fit 2 small fans or would it be better with 1 big fan? thanks

2 smaller ones. For two

2 smaller ones. For two reasons. Two smaller ones will cover more of the radiater face than one big one. secondly if one fails you still have the other to get home with.

Electric fans

Electric fans were fitted to some models, but not European models, so finding some is going to be difficult.
With the Fourtrak's oversized cooling system it would be better to fit two fans, these operate at differing temperatures.

Fan one will cut in at a pre-determined temperature, fan two will cut in at a higher pre determined temperature, so for normal road and easy off road work only one fan will operate. During extreme off road work, or heavy towing, if the first fan does not cool sufficiently, the second fan will cut in to assist it.

Peugeot electric fans were twin set up's, and were actually fitted by Range Rover on the P38 models, these were effective in cooling such a large engine, so there is a possibility.

Companies such as "Kenlowe" will advise accordingly and offer a complete kit to match your vehicle.

Fan size or radiator area coverage is not the issue, it is the air flow capacity of the fan which matters, these are usually housed within a deflector housing which dissipates the cooling air to the radiator frontal area.

So it's not how big it is,

So it's not how big it is, but how you use it? Sounds familiar. Assasin is totally right, if you are using a bought kit, or constructing your own cowling (which you should). However if you are just putting whatever you can get from the local scrapies as close to the rad as you can, my advise is valid. Remember though that without a cowling the fan / fans must be right against the rad as air flow will take the path of least resistanc (Ie, around the rad rather than through it).
