Photo's of electric fans etc.

Anyone who is thinking about doing an electric fan conversion on their T2:

I used a 16" initially, and proved that it couldnt keep the truck cool under prolonged high load when towing at low speeds.

Whislt doing the a/c work (see other post) I added a 2nd 11" as you can see.

The viscous unit stays in place, and with slim line fans there is just enough clearance.

I mounted both fans with the zip tie leg things that go through the rad core. If you have a/c then you will need to remove the rad from the car to pass the zips through the core. They are abit heath-robinson, but seem to do the job well enough.

I have a kenlowe thermostat that runs both fans through a relay. Setting it is abit vague- i basically held the truck at 3000rpm until the temp gauge just started to rise then wound the knob so the fans kicked in.

I have a manual overide, and also a blocking diode wired into the a/c aux fan, so that when the a/c is on the rad fans also are, but with the a/c off the rad fans don't back feed the aux-fan, this greatly improves airflow across the condensor as we now dont have a viscous fan helping out.

Hope its some use to some T2'ers!

Tim.

HI ya looks good grate job :thumb2

Did this mod to my patrol last summer, only 1 17" the dual speed job as recommended by kenlow, but wish i a had gone for 2 16" as fitted to Rangrovers.
Its work great until I tow in very hot weather or in South of france. Do you tow a caravan at all would like to now how u get on with that

Just one thing are you into off roading and laning if so get some proper metal brackets made
the fixing through the Rad work well but dont hold up of road they damage the fins and heard can even make the rad even leak.

Have you noticed any difference in fuel or anything else?

The truck tows a 2.5t twin axled box trailer about 50% of the time. It went to north wales last weekend in the 25deg C heat over Dinas Mauldwyn (sp?) and the single fan was struggling to keep it cool.

I dont go laning...

Since ditching the viscous fan mpg has improved 2-3 mpg over the winter months as she warms up alot quicker. No real change in the summer months, other than no irritating roaring fan everytime you start up! I get 32-34mpg solo, 23-25 towing.

It has considerable turbo and fuelling mods and is throwing out 160-170bhp at the moment, so cooling has become an issue when under prolonged high load towing up hills etc...

Sounds like my patrol that does
Running both Fuel mod and Turbo increase plus built a 3" exhaust system have got an over boost issue at the moment
but much better of the mark probably 180/190 bhp I have been looking for a rolling road that would take the patrol and test it

yes get little improvement in fuel, but the engine is much quieter no roar and warms up much quicker,
I have no issues in the Uk or while slow driving off road and even better when wading in deep water.
But temp only climbs while towing up long hills with my big twin Axle van on the back.
I have fitted Exhaust Temp Gage so i don't blow pot 3/4 on the 3lt its was common on early 3L T2s and patrols.

So next plan ill move the singe fan over and get hold of new second fan :thumb2

Nice 1 M8

Is cable tying the fans to the rad core a recognised way of attaching the fans?

 

[jims-terrano]

I've seen it before on kit cars but it does make you think a little doesn't it. I thought about this type of mod for mine a few years ago but my wallet said no.

Most fan kits come with the fixings they are like long pins with onway washers witch slide on the pins see below kits from demontweeks

Nice one Timbo. I was wondering about fitting them on the inside or the outside:augie Prefer it your way as there's room for a decent intercooler up front then:sly
Cheers for the advice too
