I’ve Hyundai Sonata 2011, In temperature Gauge, it has total 12 bars and normal temperature is 5 bars (it always stays there).
Today’s morning, when I started my car after night. It’s my usual to wait for temperature gauge to reach at five bars and it takes usually 2 to 2:30 minutes to reach but today it stayed at one bar, so I just put my car in drive and start driving, I noticed that the temperature bar goes to 5 bars in seconds and then comes back to 1 bar then then again goes to 5 bar within few seconds and then stayed there as normal, and I noticed this thing two times today after cold start.
I want to know the possible reasons of this, though the temperature bar didn’t exceed the normal limit which is beyond 5 bars, still it’s not normal as I’m living in Saudi Arabia and here these days temperature goes up to 47 degrees so I’m just curious about temperature.
I’ve attached the picture of my temperature gauge at it’s normal state “5 bars”.
