Have noticed that my patrol gets very hot and sometimes even boils when in 4wd and have the air conditioner on , any ideas on what could be the problem.

Not specific to your car but I'd be checking coolant level, radiator cap and thermostat operation and depending on how many Ks you've done drain and flush cooling system. Also check out post 20842 by Roachie. You are obviously working it pretty hard when in 4wd with the A/c on, the A/c should turn off if the engine gets too hot, does it do this?

It's a car, they get hot, radiators block up, thermostats fail to open, electric thermofans stop working, water pumps wear out, radiator caps leak, head gaskets leak, clutch fans become ineffective, Mars circles Uranis and the tide goes up and down !!!

It's all part of life.

Radiator repairers/mechanics fix them, everyone is happy again.

WOW I really am feeling cynical today.

yea but it pays to nail down the problem 1st or you will get a new radiator new water pump new head gasket for 1,800 dollars when all you needed was a new rad cap

If it has been as hot in your neck of the woods as it has been in Kal then no wonder even the work tojos have been getting warm. I am assuming it is not that old so unless you have been using bore water to fill it up the radiator shouldnt be blocked inside
1st thing I would do is look for seeds blocking the radiator this not only involves chacking the front of the air con condensor but looking between the radiator and condenseras crap gets sucked up here and blocks the rad no worries. Also when the gauge heads north next time jump out and check the fan out as you turn it off. With the motor stopped it should do no more than 1 turn otherwise it needs service/replacement. Ccheck for mystery coolant loss and cracked head (unlikely) otherwise as per previos reply. If all draws a blank get the radiator removed and rodded as there could be internal blockages

Yep, Davoe's on the money.

Is it a new GU 3.0 Turbo Diesel or the old GQ petrol 3.0 6 cylinder? It it's the older type it is quite liley that:

A: The radiator and or block is clogged and needs a good flush and possible recor.

B: The clutch fan is rooted and needs servicing/replacing.

C: All of the above.

If it's a newby it probally just needs a flush (as they use eletric thermo fans I think anyway).
Or possible as suggested above a radiator cap.

Take my advise on either of these vehicles, as soon as the needle starts to rise back off and don't think "Oh it's ok it's not in the red yet". Once these factory temp guages start to rise it means she's bloody hot and not happy, if you aggrovate it you'll have an expensive cracked head repair bill in your hand faster than you can say "wad-i-do?"!
