Hello guys right this morning i went to start the old girl up and it was -2 and glow plug light came on and all was fine,now 5hrs later after it had been standing in the freezing cold and was 0.5 went to start it up and guess what no glow plug lights Car started fine though ! any ideas ????
I went on a 30 min drive in which time the car started to heat up inside but temp reading didn't move,when i stopped i let the car run for at least 20 mins just to see if temp would rise but it never,now ive had this before when ive had heater on full and blowers on and temp barley moved but when i turned heating down and fan speed the temp started to move.
Question is do you think there's a problem with either temp gauge or thermostat ?
