Check the cap as well but Im also curious about your water pump because if its one of those part store brands could be another issue, I never trust that shit, it breaks way too often.

both sensors work but when i get money ill buy new ones
both fans also work
i have a nismo thermostat and the car runs a lot cooler when its not overheating
water pump was bought from autozone i think its duralast brand

The cold air inside is a definite sign that the thermostat is closed, you can also grab the lower radiator hose, if it's cold at the engine side then it's not opening. I've done cars that were fine for a few days then got hot again, and some that bled once and never had a problem again, every car is different. Running without a thermostat though is stupid, the engine has to reach operating temperature to achieve the correct tolerances. And trusting the OE gauge is stupid, there is no common point where it registers too hot until the engine has already sustained damage.

im using a nismo thermostat. as far as clipping and drilling ill try it
every time it overheats i check the hoses. most of the time the top hose is really hot and the bottom hose is warm/cool so i bleed for air bubbles

Bleed system, jack car up high, heater full blast, use funnel..put a little extra coolant/distilled water so while you're squeezing the upper/lower radiator hoses it doesn't spill out and helps getting more air out the system
don't forget about that bleeder screw on the intake manifold (ka24de)
I found my problem of overheating was having no thermostat (just bought the car/found out it didn't have one after overheating problems), put a nismo thermostat on there, no problems so far, but i just put it on a few days ago

both fans work. also did the whole bleeding system thing just like that everytime it overheats. its fine for a week and overheats again. also using a nismo thermostat

bled the system numerous times the proper way. have yet to get it pressure tested but definitely no visible leaks
