ive replaced the thermostat & the fan motor, it seems to overheat more when im at a stop or stopn go traffic...it doesnt overheat right away, its usually when i drive about 20 mins or longer...the oil is fine, the 50/50 antifreeze is fine, i can hear the overflow boiling... my question is could an electrical problem make it overheat? reason why is my alarm beeps spiratically by itself when cars pass by lol also the winshield wipers work fine except when i turn them on high then they dont work at all... the inside lights seem to dim a bit when i turn the lights on....however it might be something non related, can someone help pleaseeee this is so frustrating and i cant keep spending money on things that dont make a difference!
