......... Also I would not leave that radiator cap loose that lack of pressure me be why you're Head gasket failed. that weeping radiator may have been going on for a while. Without that pressurizing the system the coolant will boil in the hot part of the engine creating pressure where it shouldn't be.
Not likely. The only thing that you were doing is possibly allowing the coolant to boil at a lower temp than normal. The ECU is measuring temperature and as long as the temp stayed below the boiling temp of unpressurized coolant(217 or so), the ECU wouldn't know anything.They said that by leaving the radiator cap unscrewed, it could keep the engine control computer from running in the 'closed loop' status, thereby making the engine run too rich and affecting the mileage, amongst other things.

You would think that an auto shop would know better than this. Amazing!
MT. You mean like the fuel lines on Ford now with the O-ring type push lock connectors?

The cap doesn't do anything to raise the temperature that the coolant gets to. Only thing it does is raise the boiling temp.
I can drive my Silverado around all day at it will never get above 190. Trust me, if I remove the cap, the temp will stay at 190. If I take the thermostat out, that would be another story. Maybe that is what your relative did and is confused.
Wow. My 55 Volkswagen bug never had these problems.
Need to train your relative to check fluid levels occasionally.
So it was an overheat condition due to low coolant level and not a temp low threshold like you originally said?
Yeah...and you never had any problems with your gas gauge either.Wow. My 55 Volkswagen bug never had these problems.
