Hey, I'm a bit used to mechanics of a old V8's... not this new stuff. I have a couple major clues here on the overheating.
My wife's '06 Tribeca occasionally starts overheating when she idles, the temp gauge goes up to 4/5ths or so. Then it hovers between 50% and a little over when moving.
The big odd clue is that the engine was hesitating to idle upon cranking, rough for the first 20 seconds, or until you mashed the gas once. It happened for a few weeks, so it wasn't simply bad gas. For a couple weeks or so, we were hearing a metal scrubbing squeak noise too.
But then one day
my wife called and said she thought the engine died, it was sputtering, apparently made some clunky noise, and some shrills
. Found out in the mix of these issues, that the coil pack on cylinder 1 wasn't connected well. So I fixed that.
So it's cranking, idling fairly well on crank, and running fine... except we get the overheat when stopping at long traffic lights, etc. I don't hear any more odd noise anymore. Weird weird.
unno:
I've checked oil and coolant levels... they are clean and staying at level. We do have some oil drips. Valve cover gaskets have been replaced, and plugs. Might be a slight head gasket or main seal. Just a few drops a day kind of thing.
I've pondered water pump failure, like maybe it exploded and the noise my wife heard was it tearing up the metal bits???
Maybe the thermostat is stuck closed???
