nissan patrol air conditioner

Hi Graham,

I have spent around $1100 since i have left Darwin trying to find what the problem is, some say its a heat issue, so i fixed that, but the air con only cuts out when the van is hooked up.
To answer your question the day was just over 40 degs, and the car,s temp sat on about 3/4. Travel speed 70 to 80km,s and a tail wind.
Thanks Troy

Hi Graham,
It normally happens about 5 or 6 klm down the road,
Thank's for the web address i will have a look at it.

G,day Troll 81,
Haave just got back into reception, sorry for the long delay in a responce.
Our air con cuts out once the temp gauge hits half. i spoke to a bloke in Newman who mentioned the second fan up front.
Thanks for your advice.
Troy

G'day Timbo,
Been out of range, sorry for the late response,
The foot is generally hard to the floor towing the van,
4th gear, about 80 to 90klm and 2200 rpm's.
I didn't know about the pedal switch, i will try it next time the vans hooked on.
Thank's
Troy

Not my 4.2!!!!! In fact I am surprised that the aircon still works with all the hard work the bush taxi has done :-) But then again....its a GQ....lol

Cheers

Yes that is how it works.

Turns off the A/C when radiator temperature is too high. Better to turn off the A/C and keep going!

Check out the cooling system. Could be somethong simple like fans not comming on.

Hi Dodger,
Just back in reception, sorry for the late reply.

Our air con cuts out about 5 k's down the road and the wont come back on until we book into the next caravan park, about 200 to 300 k's down the road (lol).
Have had the radiator flushed twice this year, last time in Broome, about 2 weeks ago.
Had a look at all the sensors and found that the previous owner had bridged one of the sensors. so i cut it to see what would happen. the fan went a bit haywire for a while but no change in the air con's performance, so i hooked it back up.
Thanks for the info.

I should clarify, I was just kidding with comments about Roachie. He has helped me heaps and given me great answers to many difficult problems I have had and I am sure if you ask he would do similar for you too.

Regards, Trevor.

Hey Trevor, is this more of a problem with autos than manuals or does it affect both?

Timbo, my reference is to personal experience surrounding the 4.2 turbo diesel GU's which in Aus were only manual. I am not sure (certainly I am not aware of)if the same problems exist in petrol or 4 banger diesels which had the option of manual and auto. It certainly is very common in the 4.2's though.

Hope this clarifies.
Trevor.

Thanks Trevor, just wondering because I know that autos often heat up quicker when towing. I was planning to look at the 4.2L TD Patrol (along with a few other vehicles) for my next vehicle. I'm not likely to be towing anything for travelling (as long as I can avoid it) so overheating shouldn't be an issue, right?

If my vehicle is loaded and I mean LOADED, I can get it to run hot on long hard climbs but nowhere near like when I am towing. I have had one of my 4.2's from brand new and it now has 380+ thousand k's on it so even running them hot doesn't effect long term performance (if you are not stupid of course and actually overheat them good and proper). I most certainly would buy another one again (as I have just 12 months ago) but be understanding of their inherent design.

Cheers, Trevor.

Hi Trevor,
Sorry for the late reply, have just git back into Port Headland, i will be going to the nissan dealer tomorrow to ask about this part.
Thanks for your help.

I had problems with my radiator and put in a new one. Could not get an alloy one. Since then have had problems with air-conditioner when towing or if I travel at highway speeds.

Not having an operating air-conditioner in my vehicle is a problem. You may believe that your motors cooling is far more important than getting cool fresh air in your face. However in my situation not get cool fresh air in my wife's face endangers my life.

I don't want to go to the expense of purchasing another radiator. If you have any ideas let me know. You may save my life.

G'day BOC

Thanks for your help.

G'day ferris,

Can you give me anymore info on this PWR radiator.
Thanks ,
Troy

Troy,

Here is the link to their web site.http://www.pwr.com.au/#/view=home/http://www.pwr.com.au/#/view=home/

They are based out of the Gold Coast and l found them to be most helpful, but very expensive. Expensive enough to be individually listed on my insurance policy.

The radiator provides about 50% more cooling l believe, and as l said in the original post I've not had a moments trouble since. Before going down this path l explored larger thermo fans etc..., gave all that a way as a learning experience. To me the quality is long remembered after the price was forgotten.

We had quite a few teething problems, and the radiator had to be freighted back a couple of times to be modified to fit properly, and l had to modify the inter cooler mounts to get the radiator in. PWR were very helpful, and although they didn't say so at the time, l suspect l was one of their first customers with this model radiator.

There are other brands on the market, some of which are cheaper. I haven't seen the others but l was most impressed with PWR's build quality.

If you do order one of these radiators, be careful as Mr Nissan most considerately put a couple of different types of radiators in their 4.2 Patrols. Get a spec sheet from PWR and carefully compare their specs with your radiator.

Good Luck/

Ferris
