Need some advice
Start off with I have a medium size leak in my radiator, which I keep it pretty full as best as I can. But I have noticed since the leak my temp gauge will sit at 200 like it used to then when I start to drive and come to a stop light or something it will creap up to about 210-220 degrees, then when I start to drive again it will go back down to 200 like it should, and even when I am idle and it goes to 210 or so then it will go back down to 200, so it is not getting to the red line but a little above 200, is this normal? Even in the cold weather it does this. I also can smell the radiator when I park and walk near the engine. Is it normal to go up to 210-220 and then back down rather quickly? I know if it gets in the red I will shut off the car. But My father said it seems normal to go up a bit then back down again. Let me know what you all think.
