Cheer I just messages you hope you don't mind, I haven't heard her kick in yet and when I opened the engine the block was piping hot, just abit worried!
The V6 does get quite hot without actually over heating. If the temperature gauge moves, then assume it works. Any codes from the pedal trick? ECU temp sensor is different to the gauge one and will show a code if faulty.
Do the fans kick in? There are two thermoswitches in the left hand end of the radiator, one powers the main fan relay and the other regulates the fan speed of the front fans. Aircon off, the front fans only run when the engine starts to get too hot.
Aircon on, the front fans should run constantly, getting faster if the temp gets too high, think idling in traffic on a hot day...
