It can be caused by any number of things.
A stuck thermostat, low coolant, failed water pump, and so on.
The general answer is too much heat from the engine.

SOURCE: possible cracked block or head

Have you checed the thermostat, often when they are locked closed a vehicle will overheat and "regergitate" fluid through the overflow. And just so you know noone can tell by a "carbonation test if you have a problemb. (a carbonation test tells you af a change in ph.) wich is not always the affect or result of a blown head/ head gasket.

My sugestion would be change the thermostat. ($20.00) flush cooling system. (Do it yourself $15.00/ and a hose) Drain water and fill with 50/50 mix of coolant and water.

SOURCE: Torque and sequence to Intake Manifold for 3.3L Nissan Xterra 2000

Hi El Faraon,
I believe that you're dealing with 12 mm bolts and nuts....THESE ARE NOT THE SPECS FOR YOUR ENGINE, but I believe that if you use them you'll be close....Tighten in three stages up to 22nm....choose the bolts from the centre of the manifold and circle outwards until you reach the last one.....It may be a good idea to draw an overhead or plan view of the unit, marking out the bolt positions.....Start at the centre and mark the sequence and follow that....What is important is starting at the centre, so that nothing becomes warped....

Hope this helps,

Regards, Johngee10

SOURCE: 2000 Sunfire coolant problem. Engine overheating,

ok, its time for a radiator flush. there is major sludge in the internals of this radiator. Make sure the thermostat is in the correct position as well. I've seen many cars come into my shop with the thermostat inserted backwards.

SOURCE: coolant blowing out of radiator into overflow bottle at start up.

Typically would not overheat until enough coolant was lost. Find out if they mag fluxed the heads, or had it done. A lot of shops rebuild without doing this step as it's expensive. If they got a rebuilt head, again they need to know if it was mag-fluxed.
It's harder to mag flux the block while in the vehicle and assembled.

Guage showing overheat and locking up 2011 nissan urvan

steam from exhaust means engine burning water/anti-freeze -more than likely your head gasket went when your vehicle overheats [radiator not cooling] every thing else gets hot and over heats-- your transmission cooling lines are connected to radiator so your transmission will overheat ---also burning water/antifreeze messes up the power that the engine produces very low and or stall condition so vehicle wont want to move --dont drive vehicle in this condition you might get lucky and could by just a gasket change [can also be an intake gasket] but if continue you can seize engine making a repair turn into an engine replacement as well as damanging transmission

If i forgot to put wire on thermosthat will that cause radiator to blow

NO The wire was probably for the temperature sender unit and the gauge would read nothing if it was lose of overheat if it was touching metal. radiators blow from excessive pressures generated from over heat or faulty head gaskets. have a compression test done to check for blown head gaskets or cracked head/s. The radiator will crack if there is excessively low ambient temperature ( freezing) and the antifreeze is below the correct concentration

My 2006 nissan xterra is having over heat what is the cause

to many things could be the cause,this is not some thing that can be answered with out having a lot more information,could be anything from the electric fan relay bad,to a hole in the radiator,water pump out,head gasket blown,cracked head,cracked cylinder liner,too low on coolant,but a real common one in a cracked over flow tank,or no over flow tank,while your motor is running the temp will get higher while not moving,the radiator will build pressure above the the max cap pressure,and the over flow hose will deliver coolant to the over flow tank,then as the motor cools and the radiator pressure drops,then the thermostate will open and the radiator will suck the coolant back into the radiator,this will continue all day as you drive,but without an over flow tank to force coolant into,it will force it out and it will go on the ground,the when the time comes to return the coolant to the radiator,so the radiator don\'t have coolant so it will take air back into the radiator,and in no time the coolant system will be out of coolant,this is common,or there is no coolant fan,or when using the AC the electric fan isn\'t coming on,or the fan is missing the shroud,there are endless possibilitys

Engine oil getting into the radiater,any suggestions

Check your oil fill cap on the bottom for any signs of white milky looking oil, pull your dipstick and do the same. If yes, then you most likely have an intake manifold gasket leak, very, very common on these cars. Solution is to replace intake manifold gaskets, and check for signs of cracked intake while apart.

Overheating when driving no mixing of the coolant and oil

The three most likely thing's cause overheating are faulty thermostat,electric fan or clogged radiator. Only at has been overheat so much it boils dry that it will cause engine trouble. Most common problem's are blown cylinder head gasket or a cracked cylinder head.
mixing coolant and water depends on where the gasket has blown or head is cracked. You will first need to check if it actually is overheating. The reason is. If the head is cracked or gasket blown then you can get a false boiling which is compresion from the cylinders blows through the crack in the head or gasket causing the coolant to blow out of the radiator cap.Fill the radiator to the top leave the cap off then start the engine.If the water blows out then you will need to remove the cylinder head check the gasket is ok. If its damaged replace if not get the head checked for crack's. If no water blow's when you start it check the thermostat is working properly. To check the thermostat put it a in a saucepan cover it with water bring the water to the boil. It should open before the water boil's but near boiling-point. If its ok then start the engine again leave it running until it boils and check the fan is running. If that's ok then its radiator problem. Their is no way to check if the radiator is ok you will need to get a new one. One last point. If the cylinder head or gasket are faulty it was caused by overheating so by just fixing the cylinder head problem is not a cure it will overheat again. Check the three things I mentioned at the begining and told you how to check them. Hope this help's. Cheer's

My daughter's 2000 Altima looks like there is oil in the radiator and no oil in the engine. Is this a blown head gasket? Where is the drain plug for the radiator? Better yet, what is the process for...

Could be a blown Head gasket or cracked head. Should be a drain at the bottom of the radiator I think on the drivers side. You will need to pull the heads off and have them checked Magnifluxed for cracks. If they find none then install new head gaskets and see what happens. I have the torque specs for your head bolts if you need them. Let me know.
