My Fan is starting to give me the shits, Im thinking of installing Thermo's, JBolger, how hard are the EF ones to wire up?! I'm thinkin if they're beyond me I'l just run a switch into the cabin, turn them on when I see the guage getting warm...

i woudlnt recommend the switch. if you miss it, or switch on the AC, or sell the car, youll cook the engine if theyre not turned on...

the thermoswitch is just the same as a physical switch, except it has a sensor under the top radiator hose. wire this to a relay which switches battery power to the fans.

the thermoswitch should be ~$50 at autobahn.

where you set the thermoswitch

i have them kick in just after my radiator thermostat opens. this keeps them from coming on when driving on the freeway etc.

The thermo fans are very tempting. For some reason, my clutch fan seems to be coming on far less often since I installed the T5, however, they would make the car a fair bit quieter.

I got a quote for them today just out of curiosity, $170 S/H.
Not too bad I guess.

Acid, you will be far better off with the automatic thermo switch like jbolgers, you could probably just grab it off a wrecked car.

Unless it's a seriously easy installation, I wouldn't do it myself - but if it wouldn't require much labour time, it wouldn't cost much to get the auto electricians to wire it up. Any details appreciated... :)

would removint the clutch fan, and fiting a thermo fan make any difference in the power put to the rear wheels. I ask this cos there would be less load on the engine and intern put more of the power down the drivetrain ? im not saying it'll increase engine power, but put more of the power to the wheels. please correct me if im wrong.

.

If the fan clutch is working correctly then you would gain very little Hp.
If there was alot to gain then the Skyline GTR and BMW M3 wouldnt still use the conventional fan drive clutch.

Re: .

I have heard that comment about the ‘Skyline’ still using the clutch fan about a million times. There two totally different engines.

Have you considered the fact that the old EA 3.9 tends to generate a fair bit of heat (more then the Skyline), and basically uses a relatively small radiator in it's cooling system.
This means that the clutch fan of the EA is used much more often then that of the Skyline.

If the clutch fans were so good, why don't they use them in the EF-AU series????

Replacing a clutch fan with thermo fans in the EA should have a noticeable power increase at times where the clutch fan would usually be engaged.

That’s just my $3.50
