Dust in GU Patrol

We have a GU Patrol which takes in a lot of dust through the rear door. Only have to drop a wheel in the gravel to smell the dust coming in. We have heard the GU's are known for this and just wondering if any others out there have had similar problems and what (if any) the fix is.

Melissa, No-1 check the rear door catches, first open the small door & grab the large door & give it a shake if there is a bit of movement adjust the top & bottom catches in a tad this will bring the rubbers in a bit closer. No-2 On dirt roads, providing you are not closely following someone, open the vent and turn the fan on ,as this pressurises the cabin and does wonders to keep the dust out .If it gets to hot just press the a/c button ,on still leave the vent open same goes when it gets cold.
You will notice with the vent open the amount of air coming out of the vents will drop just turn the fan up a bit .My wife doesn't like the vents blowing on her all the time so I just blow the air up on the windscreen we have had several patrols all with the same problem GUs are a bit better than GQs . Also dealer fitted updated rear door seal kits don't make much difference either . Let us know how you get on
Cheers Steve

Thanks Steve! Usually travel with the AC on but on circulate rather than fresh so will try your method. I'm like your wife, don't like vents blowing on me. I think you could be right about adjusting the door latches...without checking I'm pretty sure this is some movement.

We had heard the rear door seals where updated but probably not worth the $ if it doesn't make much difference.

Thanks again.

Melissa,
make sure that you remember to go back to circulate once off the gravel as fresh makes the a/c work harder and uses a tad more juice. Fresh is also no good when following in someone's dust cloud but it does make a difference otherwise

Melissa, I can't speak about the GU Patrol becasue I have a 80 Series Cruiser. One day, after driving from Alice Springs to Boulia, I came across a guy who had done the same in his identical 80 Series. His truck was full of dust and mine was clean. He was a bit of a know-all but couldn't understand what had happened. If he'd asked nicely I would have told him the trick is to keep a positive pressure in the cabin. This means never putting the ventilation on Recirculation except momentarily when overtaking and passing other vehicles. Drawing clean air in through the front vents (with or without the fan running) creates a positive pressure so there is no vaccuum at the back of the vehicle to suck in dust. Apart from leaking door seals all vehicles have rear vents which will suck in dust if you travel without allowing fresh air in through your ventilation system. If your problem persists then your door seals must be REALLY bad. I hope this helps.

This sort of info is what makes this site so good - never knew or heard mention of the positive pressure thing - will test it out and will hopefully spend considerably less time cleaning the interior when I get home from the next trip - Thanks guys

Thanks Gordon. GU is our 4th 4WD but first one we've had dust problems with. First 2 had no AC so always had windows down. Must have just been lucky with the Paj.

My experience with various cars is that opening the front windows creates a low pressure in the cabin and actually sucks in dust from everywhere!
I think this is because there is a low pressure area just behind the front pillars. Opening the window on the rear door seems to have the opposite effect so is preferred if you need outside air in quantity.

Hi Phil,

Yes you are right about the front windows and dust. That's what I was trying to say...we had to have the windows down so we just accepted the dust as the trade off.

hi melissa i remember reading either here or overlander forum about the same thing and a lot of people were talking about a visor type set up for the back door something like the visor you put on your front door windows to keep the wind out hope this helps

Hi Melissa
The A/C will greatly help with keeping the dust out, Monash Uni Melbourne did a study and you should only use the A/C or Heating on recycled air for max 20 minutes, studies show it can lead to drowsiness. There are dust reflectors for the back of the Nissan that also helps

Congrats on the new camper

Miff,

We bought our GU new about June 1998. The dust issue was more "prevalent" then, and the dealer fitted a relacement seal at no cost about 6 or 9 months after purchase. It fixed the problem for us. Can you try this approach? i.e. did you buy a new vehicle, & is it in warranty still? Try the patrol site with your Q. I also seem to remember this topic from some time back, and that several owners have had success with spacer washers on the bottom catch of the barn door.

The solution appears to be to alter the air flow over the top of the vehicle. This seems to seriously minimise the amount of dirt/dust that hangs immediately at the rear when travelling. Our roof rack, even when empty, does this.

I agree with the pressure approach. I note on another thread that you usually don't use a roof rack. If this is so, I suggest you fit a rear dust spoiler. This will help heaps...from memory the Nissan one is $ 120 approx. Easy for you or Greg(?? I forget his name right now) to fit.

Cheers

Rick

Thanks Rick, plenty to think about. No problem for Greg to fit a rear dust spoiler.

Melissa.

we had the same problem in our GU going thru Pooncarie to Menindee three times and back. Took the Patrol back to the dealer and they adjusted the rear doors for nothing. This reduced it heaps but still got a little in, then a friend with a GU told me to use petroleum jelly on the seals where they contact the body and VIOLA! no more dust!

Also agree with the fresh air deal with the aircon, it also helps heaps

Good luck, the GU is worth the dust problem

Hi Bonz,

The petroleum jelly sounds like an interesting idea. I'll keep it in mind if the a/c on fresh and adjusted back doors don't do the trick.

Just got back from a weekend away and running a/c on fresh definately helped. Also checked the rear doors and found a bit of movement so we will adjust these too (actually we bought a warranty with the car so might even ask the dealer to fix the doors next time we take it in for servicing).

Thanks heaps.

I think there is a fix for it, different door seals from other model GU..

cant remember but that was the chat on the list around 12 months ago about it.

Michelle,

The door seals on the GUII have solved the dust sealing problem as I read in a test, even without petroleum jelly, however I dont know if you cane fit them to a earlier GU?

Regards

First thing, tape up the flow through vents either side of the back window, then check the doors for the seal and tightness, keep your vent on 'fresh' NOT recycle, if you have a 'wind deflector' on the window it acts like a vacume cleaner
