Question How much power does a fan use?

Anybody know how much power the 3.9 mpi standard radiator fan eats up?

I've heard that the EF has thermo fans. Can they be swapped to the 3.9mpi and what needs to be done apart from fitting the fans, thermoswitch and power supply?

Surprisingly little provided the viscous clutch is in good condition. The primary reason for going to electric fans is noise (the EAs are noisy as hell with the h/duty fan and h/duty fan clutch).

The Fan clutch has 2 speeds, fast and slow With it on the faster speed, its feels like your driving with a trailer or 4 passangers compared to the slower speed. It feels like its sucking 50Nm :eek::eek:

It should only be on the faster speed while idling in traffic, or after you have just started the car, and it should only stay on for a minute or so. If its staying on the faster speed all the time then the clutch is stuffed, and its time for a new one (about $110 or so)

Dont think there would be much of a HP gain when changing to Thermos, but youll find the engine and airfilter wont get so dirty so quickly.

I've actually got an EL Thermo Fan unit (the fans are integral with the radiator shroud) in the shed awaiting installation to my machine. Physically it's the same as the EF fan/shroud unit.

Just before fitting a new radiator I tried the shroud/fan unit on it for fit and it looks to be okay. There are some slight differences between the ED radiator and the EF/EL radiator but they don't impact greatly, except that on the EF/EL radiator the shroud/fan unit would be slightly better secured.

It occurred to me that the best way to do it would be to actually fit an EF or EL radiator as well - that way all the mounting points on the fan/shroud unit could be done up ridgy-didge.

There's a difference between EF and EL fan units in that on the EF fan unit, one of the fans has two speeds (low/high) and the other is just on or off (ie. on=high). On the EL fan unit, both fans are just on or off.

My big plan was to get an EF fan unit and have it wired up so one fan came on low whenever the aircon was on and then both would come on (high) when the set temp was reached - and was very disappointed to discover that the EL one didn't have the two speed fan - but in another topic someone pointed out that the two speed system was probably dropped because it was found to be pointless (not enough flow on "low" to be any use?) - so now I'll just wire it all up like a dual Davies setup - ie. one fan on whenever the aircon is on and both on when the set temp is reached.

I'm still hunting for an electronic Thermo-Switch.

Thanks all.

I'm assuming that by electronic thermoswitch you mean one that can run off the existing temperature sender. If you find one let me know, because it would be neater than the "in the hose" type that are all I've found.

There's been discussion about this issue on other sites, including how to do it. Let me know if you want details.

Yeah the EL setup is better than the EF one, the half speed mode is basically usless on the EF.
