Range Rover 4.0 V8 123,000 miles.
I had overheating problems before so I changed the coolant, radiator and thermostat.
Although a bit better, the problem persists.
When in a traffic jam, with A/C running, the engine temperature slowly creeps up towards the red zone. At a certain moment the overheat problem kicks in, shutting off the A/C compressor, which stabilizes the problem. Highway driving is no problem at all, only when idling with A/C on
As soon as you start driving again, the temperature goes back to normal.
The system pressurizes well and the coolant level is stable.
Could it be a water pump problem?
