ok soo I have my 91 240sx ka and It was overheating said the temp gauge on my cluster so I pulled over checked my hoses to see if my thermostat had opened and it the hose felt warm but not as warm as the other hose from my radiator so then I got in and drove home n the gauge went back to normal and I just changed my thermostat, coolant temp sensor and thermostat temp sensor if u have ANY idea wht cld be wrong let me know

if i had to guess i would say it had an air pocket in the cooling system.

I bled the system tho? u think I shld bleed it again?

When I flushed the radiator and changed the fluid it happened to me a few times I had to take short drives and add more coolant as I went since my driveway is inclined the air bubbles in the system were a pain.

i've experienced the same problem after changing my water pump and radiator. water pump was bad. the radiator became bad when i tried to remove the hose from the top the plastic just fell apart. and in my case it was air pockets. i had to bleed the system a few times before the temp gauge would stay consistent. and that was over a week of driving it back and forwards to work, etc.

i'd advise bleeding it more maybe over a week and watching what the temp gauge does. if it continues after a few bleeds you may want to look into something else.

ok ill look into tht ill try bleeding it again

mr.nismo.

KA's can be notoriously bitchy to bleed. Jack up a bit, and put a funnel adapter kit on it and let it idle.

OP did you try topping off your coolant yet?
had the same issue when I changed all that stuff & I didn't put enough coolant in.

Coming from a long time ka owner that's swapped coolant a million times on it:
Get oem thermostat.
Buy this: Lisle 24610 Spill-Free Funnel : Amazon.com : Automotive

Or install this:

Yes it stopped after adding coolant like five times. I should have just let it idle with the cap removed while adding as needed, maybe giving it a few revs that worked on my Toyota T100.
