Ok so I purchased the car with no heater system and never had an over heating problem. Installed the components got heat, few days later car was blowing cold air and overheating while driving. I replaced the heater core, heat blew hotter and engine didnt overheat. Few days pass, engine doesnt over heat but heater takes long to blow hot air. Then a day later car starts overheating.

It slowly over heats, the e-fans dont help to cool it, now the heater blows only cold air. I replaced the thermostat last night and still overheats. I havent checked for heat yet from the heater core hoses, Im going to get the car on my lunch break and bring it to my work and check it out. Any help would be great.

put the clutch fan back on and make sure your thermostat is opening
