My 2008 4.8litre Petrol Patrol has one major flaw - cabin heats up after several hours driving. (Nissan dealer has ignored the problem as a design flaw). Has anyone else come across this problem ? Any solutions remedies are welcome?

You could try some silver sarking on the firewall right down to the gearbox tunnel. It would be a fiddly job but you could do it in small sections as you cut it out round the items on the firewall.
Silver side facing out since your not dealing with the sunlight like the builders would be on roofing jobs.

Having a shed built a few yrs back they used a double sided silver bubble rap type product on the roof. They gave me a beer bottle cooler as a gift made from the stuff, you could not tear it.

Adding a bonnet scoop may also help in the flow of air out of the engine bay.?

Just an idea.

try taking your patrol to an airconditioning specialist, it is probably a sticking tx valve. i am on my 3rd new patrol an had a nissan service agency for 16 years and have not had this problem. a good trick is to put a thermometer in the vent and measure the change, your dealer cant argue with hard evidence. good luck.

Have always had a thermometer in dash vent of the three Nissans, the aircon is supercool down to 1.0°C out of the vent. As mentioned the most likely problem you have is the valve passing if not, why not just turn your aircon on when the cab warms up?
A mate of mine used to complain about his Toyota cab overheating and when I asked him whether he had his aircon running his answer was "I don't like driving with the windows shut." scratch

Wilm2,
For starters if you check the outside ambient temperature, (ie: hang thermometer out the window while travelling) then place it in one of the vents, without the aircon on and compare, if there isn't a great variation the heat must be transfering through the firewall.
Another point to check is that you don't have the air-con recirculation button depressed?

For the sake of comfort, if your engine isn't overheating, use the aircon, the increase in fuel consumption would be minimal if you drive within legal limits?
Your next best option is as suggested, fit a bonnet scoop to blow the hot air down out of the engine bay.
Maybe you can fit a second electric fan behind the grill with the petrol, you can't with 4.2 Diesel?

Let us know how you get on.
Cheers
Peter

I assume it is up through the floor and firewall ? if so Clark rubber have a rubber backed aluminium looking sheet in varying thickness, told it to many patrol and cruiser owners, very happy travellers now and way less heat Very Happy Very Happy

Cabin Heat 2008 patrol Empty re cabin heat

Hi, We to have had real issues with our nissan navara (2006) 3lt STR ute. The heat on passenger side of cab floor was getting so hot after half hour driving that we had two floor mats and a yellow pages phone book under mats so wife could keep feet on floor. ( always had hot water for a coffee) When car was 6mth old the rubber mat was replaced under warranty as had perished and was falling apart. Nissan was no help. We do not tow but have a carry me camper on back and all set up travelling full time camper and contents weight was 950kg plus. We showed one nissan dealer problem and broke an egg on floor and was cooked in 2 minutes. Nissans answer, travel in 4th gear. that will sort it out. (idiots) We finally got problem fixed about 2mth before warrenty ran out when they finaslly pulled out gearbos and replaced bearings and other bits. Now no problems. We were always told that no other nissans had floor heat problems. Cheers travelergold.
