Had a whale of a time last time coming home during which I battled with a Lupo GTI and new shape Celica, evenually showed them a clean pair of heals, so it was fair to say i was driving the car hard. Having slowed down to take my bow from the catching opponents I noticed the temp guage rising rapidly - bugger ? Normally it sits at 12 o'clock yet now it began to head towards 10 past. I slowed and let things cool. No liquid loss or anything, not a drop - huh !? Temp warning light now comes on when I start the car and it warms quickly with temp gauge settling around 5 past. Checked under bonnet, nothing sprayed anywhere yet fans not working, any ideas anyone ??
