After some weeks of rain I finally did some work on the car.
So overall I fitted a new thermostat, cleaned both jiggle valves (but were not blocked anyway),
fitted a new temp fan sensor, flushed the cooling system, refilled, bled, bled, bled again, new expansion tank cap.
Drove to work this morning - most stressful trip I ever did, pure paranoia!
But the temp gauge seems to be more sensitive than in the past. So far it was quite steady below the half mark,
no matter if driving on the motorway or sitting in city traffic.
Now it clearly moves when driving in the city or waiting in a queue. Not alarming but it reaches the middle mark then.
(Guess how my blood pressure rose when I noticed this!)
Of course I'd expect the engine to get a little warmer in slower traffic - I'm just wondering why the gauge is more sensitive now?
Or is this just a symptom of my paranoia?
