you should presure check your radiator, check your oil, see if it looks like you have coolant in your oil (should look like chocolate milk) (head gasket), just have your radiator presure checked
hope that helps

Same thing happened to me before after changing the thermostat and water pump on my S14, end up being me not bleeding the coolant enough. Try bleeding the coolant again and check back.

yea bleed your coolant, you probably have an air bubble in the system, heres how to do it...

Procedure to drain, flush, and refill coolant on 240sx.

1. Move heater "Temp" control lever all the way to "Hot" position.
2. Remove undercover.
3. Open drain plug at the bottom of the radiator, and remove radiator cap.
4. Remove drain plug on cylinder block.
5. Close drain plug and tighten drain plug securely.
6. Open air relief plug (right above where the upper radiator hose attaches to the engine).
7. Fill radiator with water and close air relief plug and radiator cap.
8. Run engine and warm it up sufficiently.
9. Rev engine 2 or 3 times under no-load.
10. Stop engine and wait until it cools down.
11. Repeat step 2 through step 9 until clear water begins to drain from radiator.
12. Drain water.
13. Open radiator cap and air relief plug.
14. Fill radiator with coolant up to specified level.
15. Close air relief plug.
16. Remove reservior tank, drain coolant, then clean reservior tank.
17. Install reservior tank and fill it with coolant up to "Max" level and then install radiator cap.
18. Run engine and warm it up sufficiently.
19. Rev engine 2 or 3 times under no-load.
20. Stop engine and cool it down, then add coolant as necessary.


Quick Tip: After flushing your cooling system, make sure you fill up your cooling system completely. The KA24 engines seem to like to trap air in the system and needs to be bled completely. An easy way to bleed the system is to run the engine, and keep adding water/coolant into the radiator while shaking various parts of the car. I liked to just push down on the front bumper. Shaking the front end side to side also helped. It took about 30 minutes of this to get all of the air out.
