Got to disagree with that Shayne, yes the auto's rad design does have it's prone points. However, even though that isn't the case on the manual you need to be very aware of how hot the engine is getting. There are plenty of warped and cracked head stories all over the net for the 1KZ-TE engines on manual trucks.
As Chris says, if you have the aircon rad you will soon find yourself overheating if you've been playing in mud or muddy water. The aircon rad gets blocked as well as the cooling rad, trouble is you can't clean the cooling rad easily as the space between the two is really tight and the shroud hides a lot of muck around its perimeter.
I had exactly this problem coming home after a play site session and had to have Mrs Trev tow me home in the 120, to that end I'm going to remove the aircon from the truck which means I can carry a pump sprayer and wash out the cooling rad after playing.
