If it's constant..then it's compression leaking to yer cooling system %26amp; you've a bad head gasket or head. =^ (

IF YOU START IT COLD AND IT DEVELOPS heat to blow water within a mile or less you might have exhaust blowing into your water jacket via bad head gasket,cracked head etc...

open the recovery bottle and smell inside.dont attempt it when it is hot.it will hurt. allot. if it has a foul or foreign aroma it probably happened.compare smelling a known good car. also if you have the radiator cap off full of water ,start and look for steady bubbles coming up to surface of warter.this will be the compression pushing into the water jacket.

if confirmed it is a major repair and often; especially if negligent and running the motor hot ,total destruction of the engine is accomplished. takes the temper out of the rings.i've even seen blueing of the cylinder walls.only total stupidity will cause destruction like that.

when engine temp is over 265 at most,just turn it off.running it will destroy it. if you must you can let it cool for an hour, start and run untill it gets 220 give or take a little. stop again.cool another hour.repeat as necessary.its the only way to movea hot runner without destroying your wallet..good luck.
You have a bad head gasket, possibly a cracked head. Remove both heads and have them inspected at a competent machine shop, use a high quality head gasket like Fel-Pro when you re-install the heads. If the car has high mileage and the cylinders look scuffed , not nice and shiney you might want to look for a replacement engine from a Junkyard or a wrecked car, there are tons of 3.1's all over, a good used engine will run $300 - 550.
Very common on that vehicle is that your intake manifold gasket is leaking.Normally shops are going to charge 8-900 dollars to repair . Chances are you are leaking coolant form your intake and which is burning off of your engine.Which means your car is over heating due to lack of coolant.
From your question the only thing I wonder is are you adding coolant/antifreeze to the water? Sometimes this will help your motor to run cooler. If you are there may be a blockage in the oil pumping system not allowing it to cool either. I know these are way out there but it seems like you have done pretty much everything else. I hope this helps.

Check the lubricating systems for flow and pressure ...
cracked or warped heads, blown head gasket? do you have any oil in your coolant, or coolant in your oil. Check for that and get back to us. (milkshake colored oil / droplets in the radiator)
Sounds like a blown head gasket. Cylinder pressure from the engine might be leaking into the cooling jacket of the engine pressurizing the radiator and hoses etc. You need to have the engine tested with a cylinder leak down tester to check for bad gaskets. If you are describing water coming out of the engine it could be the gasket from the intake manifold to the heads. Another might be a core/freeze plug is rusted out. When the engine is hot does the water run down the ends of the engine? Water may enter the oil if this continues.
