I wonder how long your E-fan "Ultimate defender" would survive without the use of a flat top up in Cape York or up in the Territory during the wet[bigwhistle]Quote:
The goal was to build the ultimate Defender and for me the e.fan set up has been great and has opened up the engine bay to accommodate other modifications.
Maybe it would run perfectly in the City But that isn't what Defenders are designed to do best.

I do wonder what an electrically engaged fan would perform like in this situation, obviously no good with an intercooler, but obviously have good Application and success in the trucking industry
It went from Melbourne to the Tip of Cape York and back not many months ago. Done in 5 weeks. The Disco with us rolled just outside Bamaga and the Defender had to cart all its kit back to Melbourne when it was already heavy loaded. It was packed to the rafters and then onto the roof! It done the old telegraph track, all the crossing, got covered in mud and the only issue suffered was the starter motor packed in from all the water exposure! But even that didnt stop it, being the ultimate defender it just needed a little push start to roll back into action. [biggrin]Quote:

With the efan positioned behind the radiator the radiator is more likely to fill with mud than the rad fan! It is very hard to get mud flung up the back of the radiator.
Our Pit Haulers use hydraulically driven fans.
No electric set up can match the cfm of a shrouded hard driven fan on the same size radiator.
I find the claim that an efan is quicker to replace laughable.
I can remove the viscous fan from my TD5 in less than 2 minutes and that includes lifting the bonnet
Sorry to tell some of you guys but 40 degrees c is not hot by Australian standards. I have seen over 50 at 0900 in summer
Well perhaps its similar then, I can remove my e.fan in less than 2 minutes too, and all I would need to do it is a screwdriver. I could also carry a spare without taking up to much room.Quote:

With the Defender you might be wise to do the tropical mod to the radiator to help if it’s in summer.
No we are not up to 50 that Was around 0900 it got much hotter later not wanting a competition on how hot it’s been just making the point driving around Melbourne at 40 Degrees C is different than pulling fully loaded through deep sand at 60 odd degrees ground temp with a tail wind and a partially blocked radiator
For some this is at times a reality
If your efan can be removed that quickly I hope the corrugated roads don’t do it for you
:) I really appreciate all these concerns. Its a shame I cant entertain you all with tails of e.fan woe. It would be funny if it fell off. I've hammered the crap out of this landy on corrugated roads so I know how to do things up. What has fallen off over the years? hmmm... nothing worth remembering. I did crack the instrument panel off its mounts and shook the door cards loose, had to gaffer it down for the rest of the trip!Quote:

If I were to plan for a trip through the desert where peak 50C temps were expected I would service my cooling system, perhaps do the tropical mod you suggest, carry less kit and upgrade my e.fan from 180w to a two stage 360w and be very confident with it. But really I'd much rather pick a cooler time of year ( perhaps a chilly 40C ).Quote:

This is not a work vehicle, its not a daily driver, so I have the luxury of setting up the car for each trip and picking where I take it and when. Honestly, I doubt I will ever need to reinstate the viscous fan. My TDI, the way it runs, it just doesn't need it. E.fans - its not all bad :)
