can someone help me please. so i bought this rsx type s and it started overheating. i replace the fan switch, thermostat, and radiator. the fan are working with the A/C but for some reason they don't turn on to cool the engine down. i read that it could be a relay or a fuse but cant find the number and i already mess a little with the relay but the fan turn on when overheating.

yeah i filled the radiator back up after replacing it. i already replace the radiator switch too. it takes like 20 minutes for the car to start overheating. i'm about to just leave my fan on directly.

first thing to check: is there actually hot water entering the radiator?
Causes of a lack of hot water are air pockets from improper bleeding and a stuck thermostat.
If there is hot water in the radiator:
If you shorten the radiator switch contact wires, does the fan activate?
if no, check the loom. If yes, check that the switch actually works cold and hot using a multimeter.
Do all sensors read nominal and meaningful values through OBD? IAT, ECT?

Try bleeding the cooling system, sounds like you might have air bubbles in the system. Investigate about that fan too, seems like its not working properly
