i just fitted twin thermo fans today from an EF falcon, i reccomend it to anyone that doesnt have them, i didnt realise how loud the engine fan was till i started my baby up with the thermos on.

they were a bolt on fit to my car, the radiator already had the slots in the top tank for tha bolts, i couldnt believe my luck!!

i havent given it a thrash yet so i dont know if my car will go any faster, but the mod is worth it for the noise factor alone.

they are operated by a davies craig thermo switch and some hidden relays, the switch is visible above the throttle body.

nice engine bay mate!

im doing the thermo conversion this weekend, im half way through it at the moment. I cant wait to get rid of the noise either...and hopefully pick up a few extra HP on the way.

yeah nice engine bay
did you connect the thermo to the A/C system?
if you didn't you could damage your A/C compressor

edxr8ebgt makes wiring lumes that looks factory and works mint
he can supply relays, fans, temp, switchs.

if any one needs it

For anyone interested in the best thermo control circuit around, contact me and I can send some info.
bpt@norcom.net.au
The loom comes complete ready to just clip into place and does not use capillary tubes. Looks factory and performs like factory.

Wot did the craig davies wiring kit cost you?

EDxr8EBgt,

Do you do wiring looms to fit ef/el fans to an EB? Need them for the EL 5.0L I'm putting in.

I have heard that ef's run 12v and el's run 7v, is this true?

oh great, now i know, i went to a million differnt places trying to find a thermoswitch that would operate my fans that did not require the gay capillary tube, and the davies craig one was all they had.

it cost $52 from repco, autobarn costs only about $45 but they were out of stock, and supercheap they are about $75!!!

i just got the switch and fans and did the wiring harness myself.

my AC is inop at the moment due to a stuffed compressor, i found where the wiring for the compressor clutch goes tonite, and when i get a new compressor i will wire it up to run the fan on the exhaust side of the car whenever the AC is on.

i will also 'stage' the fans in a little while, so the exhaust side fan comes on at just above operating temp, then if the temp still rises the second one comes on at say, 5-10 degrees above the first fans 'on' temp, but to do that i need another temp switch, and i dont want another bloody capillary tube in the radiator hose, i had enough trouble sealing one, bugger trying two!

EDxr8EBgt you have email!

(why run the fan on the exhaust side of the motor in preference to the intake side? to minimise the amount of hot air being blown around the pod filter, and keeping the air moving on that side of the engione bay should hopefully lower underbonnet temps a little, by blowing air past the exhaust and under the car i should be stopping a bit of heat soak from the exhaust)

oh yeah, i am getting a fiberglass shield and cold air duct made up to feed the pod with some nice cold air, i have probably lost hp over stock from just sitting the pod there in the hot air, but it makes a nice noise for the moment...

Chris Nee, Not entirely.

The EF fan assy has one fan which has an extra winding to acommodate the fan speed option. The EL fan assy has two fans which have both the same motors, it's twin speed mode is made possible through clever switching and bringing the two motors into series for low speed.

Yep, I have designed and sell a kit that make use of the full potential of the EF/ EL fan assy on an EA,EB,ED and what ever else you might want to put it on.
I developed it in the NorthWest of western Oz where the ambient temp is about 45degC average. I used to live up there and needed something reliable to cool my XR8.

Hey Rollin,

I sent you some info
