Hey gang,

Has anyone successfully fitted a second hand aircon unit, was thinking a Sanderson, Mits. Sigma or another compatible unit, to a GU Patrol 3ltr TD?
I have a 2005 GU and would like to run air tools, lockers and pumping up tyres is always helpful ;-)
Been searching the net etc and can find heaps of info for other models etc but nothing for the 3ltr – I know that there is not a lot of room but was wondering if anyone had been successful?
Will be plumbing the unit to a tank with all the usual hardware so I don’t blow myself up!
Any thoughts or suggestions would be greatly appreciated

Cheers.

Hi,

I linvestigated the possibility of this myself some time ago - unfortunately as you hasve guessed space is a big problem and where to mount the unit.

Ther only option I came up with was to remove the a/c.....and I certainly couldn't do that!

I believe someone suggested I could mount it underneath the car and run it from the propshaft......never looked to far into this due to cost and the thought of it under the car getting destroyed did not appeal to me. An electrical unit under the bonnet for around $300 so I settled for this, runs air tools from a reserve tank, pumps up tyres quickly - yet to test it with Air Lockers (anyone wishing to give me some lockers and I will test this out - in my own time of course.....:)

That could be interesting!!!!!!!!! In order to have the compressor working, you'd have be driving the vehicle.......and at a fair speed too I'd imagine........could get a bit interesting being the poor mongrel who had the job of running along beside the vehicle at around 100 k/h, holding the air hose as you tried to get the tyres pumped up.......LMAO

BTW, the air tank idea is okay for a short burst of air pressure.....unless you have a huge tank. I have a 3L + a 4L tank in the back of the patrol and that isn't enough air to even half re-inflate a 265/75 from 28psi to 42psi.

Cheers

I have seen an Endless Air set up on the 3.0 Nissan. It mounts towards the bottom of the engine on the drivers side.

Did it run off the serpentine belt or a seperate belt?

Cant say I looked that hard, I tend to try and keep away from Nissans!! I am sure if you go to the Endless Air site it will likely reveal all.

I built a system for my 60 Seires and made it run off a seperate belt from the alternator so that the origional belts stayed origional

I ran my own design on my previous vehicle, so I have no problems designing a suitabe system from scratch, I was just curious about what you saw.

My petrol cruiser was running a Sandon from a Mitsubishi, converted to greasable, it went for 12 months with no problems...put another pulley in between the fan and water pump, and ran off that....also ran a second altenator to make the aux battery a completely seperate system, with voltage sensing as per how it should be done....no problems with mix matching batteries, or taking too long to recharge...but this alt also supplies 240 volts dc for lights, grinders, drills etc, and also 185 amps of dc welding current aswell... Im sure you would have heard of these alternators before...Auto Arc...anyway, seen them used b4 in service vehicles for Dakka rally cars.
