i was having problem with my 2001 maxima overheating. so i went and change thermostat and the water control valve so when i did all that and started it for the first time with the part it went to hot like in 10min then it went down and now it start like shown on pic but it go in half half

 

You will probably need to give more detail about the kind of overheating problem you were having.
Was it overheating at idle or while you were at cruise speeds?
What made you think that you needed to change the thermostat and the water control valve?
Have you purge out the air from the system?

 

It started over heating when i got to a stop.
when i took out the thermostat and the water control valve the rubber on them were dry and like burnt.

how you purge out the air from the system???

 

It only overheat when you get to a stop? If it doesn't overheat when you are moving, you might have a problem with your fans. Have you checked to see if they are working correctly or if they are working at all?
You also might want to check if the coolant is actually circulating; at normal operating temperature, the upper inlet hose should get hot.
Air pockets in your cooling system is also a cause for overheating. After changing or replenishing your coolant, you need to purge the air out of the system by running the engine, with the radiator cap off, for about 15 miniutes, revving the engine to around 1500 rpm's every couple of minutes or so, and topping off the radiator if the coolant level goes down. After that, go for a drive then let the engine sit until it cools off a bit and check the coolant level at the radiator and reservoir; add coolant if necesary. (I think that is the procedure, someone correct me if I'm wrong).
