Hi - hope somebody can advise.
My wife has a 1.2 Renault Clio which gave her cause for concern this morning.
Whilst driving up the motorway at about 70mph the engine warning light started flashing and the temperature gauge rose to the 4th bar (it usually doesn't move from the 2nd) - anyway she nursed it back home and asked me to check the coolants etc.
I left it a few hours and then started and left it idling for about 10 minutes after checking the coolant levels and hoses etc. I then took it for a drive and gave it a bit of a harsh drive. I turned the heater on full blast on full heat and all I managed to replicate was the temperature gauge rising to the 4th bar. I took the car home and again left it idling for about an hour. During that time I turned the heater off and the gauge returned to the 2nd bar. I eventually switched off the ignition and the cooling fan started but no warning lights.
