Question about 2001 Nissan Altima
I have a 2001 nissan altima. It was leaking water from the Water pump and i always noticed that it would get hot before this. BUT, the water pump wasn't bad. It was just the gasket that was bad. So when it ran out of anti freeze or low on antifreeze, it would get hot. But it never got very hot because i checked my gauges alot. So i went and got a brand new water pump for the car and i installed it. After i installed the water pump, the car keeps getting hot and the water isn't circulating. i don't know why. I changed the radiator, the water pump(twice-New and old), and i took out the thermostat thinking that it might be closed. The sensors are good as far as i know. The car was running great until i changed pumps in the car. and now it just gets hot and the water wont circulate. any help??

Be sure there is sufficient coolant in the system. Not always as easy as it sounds (Be glad it's not a fiero, they are really fun)).
Fill it as far as you can while it's running. Let it get warm, rev it every once in a while. The level should begin to surge, let it keep surging until it lowers before adding more water. Top it off again.
Repeat the procedure until it doesn't lower any more.
This will get rid of any air pockets. Now fill the reservoir to the indicated level.
The only other thing I can suggest is making sure the water pump is the correct one as far as direction of spin. There should be an arrow indicating the direction the pulley should be turning stamped on the pump housing. Check it.
Comment me with any problems.

you may have bad waterpump,the impeller on pump may be borken, just because it doesnt leak doesnt mean its good.also could have exhaust entering cooling system (bad headgasket) if pump is good have a block test done.

the water pump and thermostat should have solved it. an air pocket can cause that but usually not to that degree.
don't get one of those cheap *** plastic impeller water pump for sissies. Get the metal impeller one. get a cool running thermostat and drill two 3/16" holes in it 180 degreess from each other. you may have installed the t-stat backwards.
