Asalam o alaikum,
I hope everyone's fine. I have driven my car on the motorway for around 50+ KM at a constant speed of 110-120+ KM/h with AC, and there were no indications of overheating. But when I stopped my car at some rushy area, the gauge went to mid level and also crossed mid level a minor, not so high, not even one third. On that day, while driving through a congested traffic area, the gauge did the same and came down to normal level after a few minutes. The next day, I took my car to the dealer to check every pipe, but none of them were leaking, even though the water level was also normal that I then test drove the car again about 30-40 KMs with an average speed of 90-100+ with AC, and also checked it in rushy areas but the temprature was normal. What could be the issue? Can any of you guide me? Is it normal behavior or not?
