Ok so it all started out with Rams stupid idea for a plastic oil cooler /filter housing which I had replaced at shop cost about $1200 well instead of upgrading to the all metal one they put in another plastic on that didnt even last 2 yrs. So of course it failed filled my radiator with oil made a hell of a mess . Well so i replaced myself with all metal one finally got all the oil out of system and believe it or not the radiator flush they sell at parts stores is crap . You want to flush it out good you use about a teaspoon of dawn dish soap and run it a couple days then dump , flush ,and refill . So then i started to hsve a problem with headlights one would go out then the other i would wiggle harness they would come back on. We all of a sudden i got a code for coolant bypass valve . So i replacrd it . Code wont clear . I followed wires from coolant bypass valve and the seem to share either s power or a ground from headlight . So what i am wondering is if this code is being triggerd by the faulty harness to headlights and how do i fix it?
