Sounds like what I would expect to hear from my lady.
She cleans, and she looks after the kids. I will take care of the vehicles.
Also, think of the environment and your gas bill, turn the truck off when your not driving. Anything over about 10 seconds of idling is just wasting gas.
heat/ac, lots of reasons to leave it running....
sometimes my truck runs for days. its overheated like a motherfawker many times too. chance i took.
I came on this thread a bit late but...dude you curse your girlfriend, drop the C word right out of the gate and expect us to focus on your vehicle? Really? An overheating engine is the least of your problems. Apologize to her, learn respect to earn respect and get back to us. BTW I haven't a clue about fixing your vehicle.
I read your entire thread.
A man never ueses the c word EVER period.
You are an ass and deserve every bit of grief you get.
great....now you guys are are acting like cunts.
seems like a good word to me

though i really only use it towards males for the most part.
you cant fix stupid, or teach common sense.
anybody over the age of 7 should have at least got out and tried to warn about the dire smokey issue from the vehicle. i have four daughters and they are teens or twenties, but all have passed this test. and at least two will eventually fail this test after passing it a few times.....
man the fawk up? i would have been pissed if someone sat there and watched my car burn down....wonder if she was smart enough to get out if it actually caught fire?
you all will maintain in that case that a good and proper "dumb cunting" (note a "dumb cunting" will not necessarily contain the words dumb or cunt in its execution) is not in order if your dumb enough to stay in a burning car.....because she was

she essentially was in a burning car.
to the op...
unless you need a electric fan, replacing the clutch and leaving the regular cooling pump in place is the most practical solution.
the inner chamber issue mentioned as well causes a creepy overheating issue. not in the scope the average shade tree deals with.
your symptoms are classic failed fan clutch.
