If you put the the pipe above the air filter then the engine is also drawing unfiltered air through the EAS box and where I go that can be a lot of dust.

Yes of course pipe should be below filter. My mistake. Have amended the statement. ;);)
 
Just reread that. Sorry, extra air. Well, that means more fuel required which means more power. Excellent.

like the idea.

No same air, the engine can only draw it what is can draw in. As long as it passes through the filter it does not really care where it comes from.

15mm tank connector and then a bit of hose pipe would be easy. Need a vacuum cleaner filter at the EAS box end perhaps. Long narrow hose though. Pressure drops off as the square of the length. Still, any air movement has to be better than none.

Rethinking this, that EAS box leaks like a seive, probably to disperse heat so it'll draw in air all over the place anyway and vacuum filter a waste of time. Probably just suck more dust through.

Suspect it only acts up if driver pack on its way out.

The largest ID hose you can get in there would be best. Apart from a couple of holes in the lower shell for water drain the EAS box is not vented at all. So any air flow through it will improve things from a heat dissipation point of view. Some sort of inlet filter would be a good idea.

Air is a strange thing it will ignore small cracks if a larger path is available to it. Of course you don't have to do it if you don't want to it is just a suggestion. 12 volt fans will also draw dust into the EAS box.;)

Yes. Mine seems to work fine so probably best leave alone. Some take theirs to more extreme environments though!
 
To my mind, adding ventilation in a hot country isn't going to achieve much, be it with a fan or using the engine intake. (I have this problem with control cabinets at work) problem is, the air is already hot and by forcing it to go somewhere you're just making it hotter.
I would be looking at why it's getting so hot in the first place and fix that.
A better way to keep it cool would be to fit a DC motor controller and run it a bit slower. Yes, it would run for longer but the heat it needs to dissipate would be less.
Last summer in Czech it was just shy of 40deg whilst I was there for 2 weeks and had no issues whatsoever with the pump.

I guess you could t a pipe into the passenger vent and then put a pipe through the bulkhead and let of the air-conditioned air blow over it!
 
That would work. On the control panels in hot countries they often have an aircon unit bolted to the side.
Moving hot air over a hot thing isn't much use.
If it's overheating there's something wrong with it.

The intercooler is behind the air con radiator and the engine cooler is behind the intercooler so that makes the air hotter going over the cooling fins and if enough air is moved over the fins then it works ok even in hot climates so any amount of air going over the compressor
when you were in the Czech Republic were you driving your car for ^ hrs a day every day you were there?

Any air will make SOME difference as long as there is a delta t (difference in temperature between the cooling medium and the thing to be cooled) and this delta t is crucial. The fluids being cooled in the radiators etc is close to 100deg so even if the ambient air is 40deg there is a 60 degree delta. Also, you mentioned fins, imagine the total surface area of those fins and compare it to the surface area of your pump. Also, how much air does a huge range rover displace? Many hundreds of times more than a computer fan will.
As to driving, I regularly drive from/to Northern Italy from Czech which is about an 8 hour drive and never a problem. Under normal driving, your compressor shouldn't be running very often anyway.
If your pump is overheating, something is wrong and needs fixing. Extra ventilation is just trying to mask the problem and it's a safe bet that when it finally lets go, it will be at the most inopportune moment.

It isn't the pump he is worried about. It is the driver pack that sometimes does odd things when it gets hot.
 
Tyres. On wammers favourite wheels. That is all.:D

Either way, it should be OK. These things were built to be able to cross deserts and I'm sure land rover will have tested them in such conditions.
The OP specifically said they wanted to cool the compressor.
 
Started to tidy the engine bay. A bit oily in places so cleaning ready to locate source. Also after a winter of neglect started cleaning interior.
 
bugger all done with the bus... Sat on it's ass waiting for a repair to the nrv's... Need a metal detector to find some pennies lying around...:(
 
Well since Friday night iv been back and forward to Aberdeen hospital 48mile each way.
My 1st child has been born.
We got him home 130am Monday morning.
After running back and forward bringing family member that can't drive and home and back a few times with missus with stuff from home.
The old bus hasn't let me down once and still started with a battery half the size it's ment to be (580cca 70ah)after leaving the sidelights on for 2hours.

It might be a bit tatty but has been perfect all weekend when its mattered
