It's not that , even if you switch it off , remove the key immediately, put it back in and start , it wont start when hot . |

With a previous car I had that problem. It was the engine was too hot, turned out it was the thermostat in the radiator was not working. The car didn't know it was too hot.

Yes, takes me back to a couple of old 3.5 V8s where the rubber diaphragms in the twin SU carbs would go soft in hot climates and not lift enough to let the air in for starting. With long arms and a screwdriver you could just about lift the carburettor piston with one hand, while turning the ignition key with the other through the driver's window.

Mine does it occasionally, never found out what courses it, would like to now if you sort it out. Common sense isn't very common.

Ok so i confirmed an overheating issue , the coolant temp reached more than 122 C on scan tool and then coolant started escaping the cap coz it over pressurised.

The manual lists only one coolant temp sensor, maybe try a different scantool? I don't recall seeing two of them using my Autel AP200.

Yeah disconnecting the the sensor sounds good , ill do it while waiting for the head gasket test kit , is the engine turned ok im going for the thermostat and full coolant flush , since the temp sensor is part of it . |

We have been in very remote outback Australia in mid 40°C & left the car idling with air conditioning running while we walked around sightseeing. I could hear both radiator fans going flat out but there was no overheating issues of any description.

I wouldn't expect overheating at idle, ever.

The Thermostat is know to fail every 10 years / 100,000 miles and when it fails it can block coolant flow and cause over heating The Coolant Fan is another know problem and if it fails then the engine will likely over heat. Does you fan turn on when you turn on the AC? or is it running when the engine is over heating? Good luck Paul |
