Had a hospital appointment yesterday morning at 9.30am. I headed off from work and after about 20 mins i noticed that the car was only sitting at about 70 degress i.e a quarter of the way round the water temp dial. It never really shifted fro this position for the next 20mins either. It was mainly stop start slow crawl traffic jam type driving although the first 5-10 mins was more 30-40mph stuff. Every other car ive owned would get up to about 90 degrees in all situations, ok it may take longer sometimes but it would still get to that temp and stay there. This is the first time i have noticed this happeneing but not sure if its actually the only time its ever happened. Oil temp only got to about the high 60's degrees also. Foe the bulk of the journey the car was more or less idling or crawling along, could this be the reason and is the normal? The outside air temperature on this journey was about 1 or 2 degrees so quite cold but ive driven at minus 13 before with other cars at full operating temperature. ANy thoughts.
