Hello folks,
As summer approaches in Australia the days have been getting a bit warmer and I have noticed the radiator fan doing a little more work, however, the last few days have ben cool and the fan still seems to be doing more work than I would expect.
Today is a pleasant 23C and as I was accelerating up to the speed limit (70kph) after having been stopped at the shops for about 20 minutes, the "engine overheating" warning came on, with the advice to drive carefully and check the coolant system. The warning went away after a minute or so, and I drove gently home (no full throttle accelerating).
When I stopped, the overflow/expansion tank appeared to be empty. I had checked it cold yesterday and it was on the Max mark. As I watched, with the engine off, I could hear the electric water pump whirring and over the period of a minute or two the overflow tank started to fill itself to the Max mark.
I went for another drive about an hour later and this time the "engine overheat" warning came on briefly after I had been stopped at the shops for about ten minutes. I have just checked the overflow tank and it is empty. Where else is there to top up the coolant system or to bleed the system? I cannot find any obvious bleed caps/valves etc.
I cannot see any coolant leaks, there is no creamy sludge in the oil filler cap.
Anyone have any ideas??
Cheers,
