Maybe it's as simple as a bad coolant temp sensor
i'm more of a jeep cj kinda guy--so i can't spit out perfect info for your rig
but these aren't expennsive
and $26 or less ain't much!---if it works, no shop involved....great!!!if it don't you now have a new part (preventative maintenance) and you also have the old one as a spare!
i don't normally suggest throwing part after part (especially expensive ones) at a possible fix
but i do get upset hearing that after expensive testing at a shop....then they stick the same $13 part in that i would have! the bill might be several hundred bucks
most of the time, aftermarket parts work just fine.....so many folks insist on "oem" parts only (many times this just makes the other guy richer, as he marks them up percentage wise)........i have found them to be defective too!
if you would get you a real vehicle (a jeep cj) we could repair you for weeks and weeks---just to get you back in tip-top shape.....i could answer with full confidence---below is one of many that enjoy/ have enjoyed assisting
keep us posted on your progress---still others may join in---or i can hunt someone down who might help better than me
