Not that weird
... its all part of that "global car" nonesense that got started in the 80's .... and the change from water to coolant.
The later model stuff is also better suited to the higher temps because of the changes in materials used in manufacture .... but still - one would hope that an "aussie" car at least has a better functioning cooling system than the imports to maintain these "designed" temps ... altho I think Auberon summed it up ....

The first 3 are consistent worldwide but the latter is the most significant of variables as you note and significantly NEGLECTED or minimised in design.

This is pretty much the worst condition my XJ has seen, on top of that it had a leaking radiator (replaced when I got back with an Adrad). I had no overheating issues, sure it got warm but nowhere near the 'red'.
I've since replaced the radiator and as preventative maintenance replaced the hoses. Other than that the rest of the cooling system is stock with 140000km on it. Is the cooling system really that bad or does it just come down to poor repair?
As an aside I'm about to put in 4.56 ratios which should reduce the load on the engine significantly.
Should also add I've had the XJ for 8 years and have put 120000 of those KM's on it with trips up to Port Douglas in Summer included in there etc.
Cheers

X 3 .... Altho I regard overheating as any temp more than fifteen degrees over the thermostat setting. If the cooling system cant keep the eng temp to somewhere around whats stamped on the thermostat - something aint right
Sheesh ... sydney must have been hot for Bell Line of Road to be those temps Steve F
Hmmmm ... just looking at the pic below ... what are
we doing differently to ensure that spiking temps from the inadequate factory cooling system dont happen then ???
Perhaps a bit of airflow out the rear corners of lifted bonnets ? / better radiators ? / snorkles ? / extractors ? / better maintenance & vehicle knowledge ? / better driving styles ? / the
correct mix of green stuff ? / electric fan control ? / better operating thermostats compared to the factory ones ... maybe even faulty factory thermostats that opened as soon as normal thermostats ?
Tis an interesting little conundrum.
