Hey fellas hope i could get some help. Got a 01 honda civic ex. Car starts heating up after about and hour of constant driving (freeway). New radiator and cap, thermostat, ac fan and might replace the coolant temp sensor. I dont think i have any leakes and dont think its the water pump. I purged the system when i replaced the radiator so dont think theres air bubbles in there. Is this normal to overheat that way? Anything helps.
