Temperature Gauge help
Just realised I had a MOT booked for Wednesday so went to check the car which I haven't used for a few months.
When I turned the ignition on before starting the car I noticed the temperature gauge went straight to max. Any ideas ? Its been so long since working on the car my mind has gone blank .
The car starts/runs ok but do not want to do any damage if it is more than the sensor. I can always rebook the MOT.
cheers for any replies
