Electric Fan - Which One?

[Pal318is]

Guys, I've just picked up my new engine for my car

What I would like to know is what would be a good electric fan to use? As I plan on chucking the old for a nice shiny new eleccy item.

While at gaydon i was talking to Daryl Zimm3 (Silver E30 M3 Fame) and he mentioned a Kenlow item, saying that there available for about £120? He also said that you get a gain in bhp due to using the eleccy item...

I would just like some info on the Fan's available and also what, if any gains can be had..

Thanks

Pal

Look up Car builder soloutions dude, they do elec fan kits @ some seriously low prices, nice slim units too

alternative, E34/32 Ac fan setup, but it will require tweaks to fit.

Or get a series 2 rs turbo fan from a yard for about £10.I had one on my sport for a few years with no problems.

[Pal318is]

Are there bhp gains to be had at all??

Thanks for the info.

Pal

Not really,maybe 1 or 2 hp but nothing you will notice.

[Pal318is]

I have one of these on my IS, fits perfectly to a IS rad mounted on a couple of air box rubbers, nice a quite.

Car never goes above half way, even in Hot central london traffic

I *think* the are made by kenlow......

Cheaper than buying a new fan clutch!

Not sure if is any faster mind...but i'm sure it all adds up!

[Pal318is]

How easy are these to fit? Series 2 jobby sounds does sound good mind you..

Fiesta 1.1 ones also work on an Is pal, fucking tight fit though

[Gwynleym10]

Series 2 fits in front of the rad.

I cut some lips in the cowling (infront of thte rad) just enough to mount the fan. I used airbox rubber mounts which you can put bolts on either end.

Mounting take 10 mins!

at the moment I have it wired into a spare rear window demister switch.

Just make sure you use the thickest wires you can afford!

Same as what I did. The power gain isn't noticable, but what is noticable is I get 5% better economy.

Using the fan from a Peugeot Partner van on mine.

Took an afternoon to make a couple of brackets for it, but it sits nicely between the front valence and the rad and does a good job of keeping the engine cool, especially when the bloody viscous that won't come off has jammed against the radiator!

[andymn]

Loadsa kenlowes on ebay mate........mine isn't that quiet, just sounds like its goin to take off.

[Gwynleym10]

Just make sure if you get pusher fan, I had an electric fan from a vectra/astra, which was a puller (i.e sits on the engine side of the rad) didn't work at all well in front of the rad.

There are a few new Audi aircon fans that are pusher. They look very nice a meaty!

[Pal318is]

Not trying to push it, but does anyone have a picture of some eleccy fans fitted by any chance?? Prefrebly the ones that are being talked about in this thread..

Thanks Again for all the info guys

E32, it comes with a handy resistor pack so you can have two speeds, it's a tight fit inbetween the front cross member thing and the slam panel because it's so big

[Jhonno]

i recognise that fan Andy..

pic of mine.



On the car :

[Boots_Walker]

anybody using the stock A/C condenser fan? i'm removing my A/C but am going to keep the condenser fan and remove our old clutchy friend.

BMW sells some brackets for mounting the fan by itself in front of the rad (rather than it being mounted to the condenser), i guess this was a factory aux-fan style setup on some non A/C cars. anybody know what (if any) e30's came out with such a setup?

[ed325i]

I used a e23 air con fan.

[Pal318is]

What can I say Chaps, thanks for all the info and pic's too..It looks like there are quite a few options available to use, bmw and non-bmw. The series 2 one looks sweet, not to big, looks just the right size.
Again apologies for my ignorance, but once the actual fan is mounted, how is it actually connected so that it works..

[StuBeeDoo]

how is it actually connected so that it works..

I don't know if this is the "right" way, but.....
Use a fused relay. I got one from Halfrauds.
Take a feed from the +ve side of the battery to the power terminal on the relay.
Take a feed from the +ve side of the coil to the fan motor.
The -ve side of the motor, and the earth terminal of the relay to a decent earth point (I used the one behind the l/h headlights).
Whatever switch you're using to the switch terminal on the relay. I got a thermal switch from Demon Tweeks (not the cheapset solution!) that has a sensor you slip inside the top rad hose.

Thanks for the advice Stuart.

I take it the same rule applies for the 4cyl & the 6cyl? Mine's a 4cyl..
Does anyone else have any knowledge of fitting these baby's?!

Type of engine doesn't affect it.
TBH, Brianmoooore's yer maan on electrics. He'll know the proper way of doing it. My way works, but that doesn't mean I've done it right.
If I was doing it again, I'd get the switch that screws into the rad.

So I take it the switch on the rad is where the fan is controlled from?? Again apologies for my ignorance

Yep. The fan needs to be switched on when the engine coolant temprature goes above normal. There should be a plug screwed into the right-hand tank of the radiator, about 3/4 of the way up. I'm not sure if it's a BMW switch that goes in there, or if it's another one that fits. I think "Templ8e30" knows the answer to this one.

[Pal318is]

Cheers Bud.

i just left mine on all the time.It couldn't be heard over the engine noise and kept the temperature at bang on half all the time once warmed up.

[Gwynleym10]

IMO have an electric fan that is on all the time is pretty pointless as it puts lots of strain on the alternator, which in turn puts the strain on the engine.

I have mine wired into the fuse box (there are loads of empty places) just get the correct blade holder to go on the end of the wire (can get it from halfords)

So it was Power wire from fusebox through bulkhead and to a switch (I used a spare rear demister switch as they have a pretty high load through them) the one wire from the Switch to the fan and obviously ground the fan next to the headlight (passenger)

If the rest of your cooloing system is in working order you will be very surprised on how little you actually need the fan on. I can get around in central London traffic for quite sometime without swithing it on, unless its really bad. I switch it on when the needle hits half way.

Thanks for that buddy Very helpful indeed..

Which fan are you running in your's then?

[Silverfang]

Could use some info for the control circuit thrmostat, Isn't there one from Burtons for like £24?

Loooks simple enough and my viscous's decided it's died, so using the heater fans to keep the good ol' M20 in mine cool!
