Do the poor mans check if you are building up presure in the radiator leave the cap loose then check the temp.
Sounds like combustion is leaking into the coolent.
Also with the radiator full does it bubble like it is boiling looking into the neck with the cap off?
Scott?

All sound like great ideas. Could be the radiator is clogged or timming is off.
I second removing the cap and looking for bubbles, maybe sticking an emissions probe in that area for gas and changing the head gasket.

check your radiator fins (i know its new, but cover bases)..
I've seen a lot of this with all kinds of cars due to air
pockets that werent completely purged.. start cold fill it up,
let it run with the cap off, heater on (fan speed low), keep
topping it off, shut the heater off, and keep topping it off until
the fans cycle twice, by then all the air should be out. Good
luck!! P.S. I have also seen thios on the box with various
body kits that cut out airflow to the radiator (like the Fab)

replacing the motor in an XB is pretty easy, i have had one out and a new one back in an hour.
If you need any tips to make the swap go faster or need help feel free to ask.

Before you jump to conclusions on the head gasket, get a vacuum gauge and see how much vacuum you're pulling at idle, if the needle is jumping all over over the place, then yep, it's the head gasket.

Heh, I guess I should have read the whole thing. Saw up to where you talked about the head gasket and figured I'd try to help out .Oh well, glad to see it up and running.

Thought I'd chime in if you have future cooling issues. Killerglass makes a shorter, non-lighted version of their glass radiator tube for around $50. I have the lit version but either are great for checking for air in the coolant, coolant contamination, and you can see when the thermastat opens up as the flow through it greatly increases.

And the Toyota engineers with their test track can only get a top speed of 103 mph for their official specs:

With your numbers, I wouldn't do a thing to that box.

Sorry to threadjack. Since we're talking about overheating issues which I think i'm having.
I have turbo kit, silicone hoses, nst pulley set (water/alt/crank).
Stock thermostat. Stock internals, new timing belt. Pushing 7psi. AFR is around 11.5-12 in boost (street tuned). Data logged my car, and the timing is conservative, no knocking/pining. My mileage is 60000 miles.
I recently did a coolant flush. When i'm driving coolant temps go between 110-130 degrees fahrenheit.
After cruising (not in boost), when I let the car slow down (letting off the throttle, not braking), I hear a sloowwwwww squeal. Its not a grinding noise. I'm pretty sure its not the brakes, and its not rod knock. Its a sound i've never heard before.
Is it possible its the water pump? how do I check if it is?
How do I check for air pockets in the radiator? or remove the air if there is any?
I also read somewhere, that it could be the head gasket? how do I check?
I'm really breaking my head over this.
Any help is greatllllyyy appreciated. Thanks.

it maybe the belt like your power steering belt or something from the pulley.....try changing your belts and what not.....im not sure on how easy it is to get to your power steering pump and what not cuzz in the xb its pretty much a pain and because of that for us it tends to be difficult to tighten the power steering belt properly.......

I was looking under my hood today and see the radiator cap has leaked water as there was white outline droppletts all over the intake and the hoses near the top. Ive yet to see the temp indicator turn red, but know the fan works and the heat takes 5 miles to generate in this cold weather.
Looks likes we are in the same boat.
