I own a March 2000, 306 GTi6 over here in Sunny France. It is a uk car that I have had no problems with....Until now !.
Over the last two days it has started to run very warm. It gets to varying temperatures over the 90 mark, before the fan actually bothers to come in (one point it was nearly on 110). Whilst the fan cools it down, it does not bring it to the 'usual' operating temp I have had before of nearly 90. I appreciate the weather here is 23 degrees, but can't see that being a problem as it did it this morning when I took my kids to school at 8.00am and the temp was only 10 degrees.
I have read the forums and tried to figure it out for myself. I have had the bleed undone, at the heater matrix pipe (is it supposed to trickle out or fly out ?), I have had the bleed open on the stat housing (just trickles out) and I have had the bleed open on the radiator top. Unfortunately all to no avail. It doesn't appear to be losing water the rad is still full and there are no deposits in the oil, on the dipstick or oil filler cap. The car still pulls really well, but I am at a loss as to what to do next.
I refilled the system and disconnected the brown plug so the fans ran on high all the time and then went for a drive. About 10 miles and 15 minutes round the lanes and although it didn't go too high, it still kept creeping up towards the 90 mark and a little bit beyond.
It's a great car, but I am completely lost as to what to do........any input would be greatly appreciated.
Thanks
