I have noticed lately that the air from vents in my 2002 GU III is actually quite warm despite being on the cool setting. The air is actually considerably warmer than that outside the vehicle. This seems to get worse after stopping for a short time, i.e. refuelling. The only way I have been able to overcome the problem has been by running the aircon for a short time after the stop and after that the air temp. seems almost acceptable. It appears that the engine heat is warming the ducting when stopped. Has anyboby else experienced similar?

Regards,

Slim.

Yup, I just noticed it today actually in the work 3.0TD 2002 Patrol. Sitting at the lights and it was almost like the heater was on, I turned the air con on as well cos it was actually getting quite warm in the cab!

Wait until you try it in Low range for a while on a warm day, then you will really notice the heat. It is normal, all the GU's do it.

I suppose we are just noticing it now because the weather has cooled a little and we shouldn't need the aircon. Unfortunately in Perth we are still getting high 20s and a few at 30+. In another month we may be grateful for the warmth. Nevertheless, I may be old fashioned but I believe that air from the vents should be at the ambient external temp.

Slim.
I have leant that the water drain tubes for the plenum chamber go into the engine compartment, if this is true then it must be the problem. Have a look and see if it is posible to extend the tubes out into the inner guards as per other models. Eric.

If you open the bonnet and look at where the bonnet hinge goes into the front of the firewall you can see that there is nothing to stop the air from the engine bay being sucked into the INTAKE for the fresh air vent which is about 150mm away under the wiper grill. Have a close look at it. Nissan do some really gumby things. You might have noticed that this is never an issue first thing in the morning when the engine is cold. Typically the air temp will be about 10 degrees hotter than ambient. good eh! Nice on a 40C day.

The best thing to do is try to block off the path for air flow as much as possible with a block of foam say 20x20x120. However, you can't block it off completely or the water that falls into the grill area can't get out and will eventually end up in the air intake.

By the way. This is not my discovery or solution, more info can be found about this issue on the patrol group website at Yahoo.

What feeling is that. The one where you paid to much money for an over rated 4wd or the one where you get to fix exactly the same amount of design problems but don't talk about because it make you feel bad about spending all that money in the first place. :-)
