I have a 2011 Hyundai Elantra. I also have a scanguage in all of my vehicles. Yesterday as I was heading home, I was at a stop light and noticed that my radiator temp was at 204 degrees instead of the usual 195-197. When I got on the freeway, my temp dropped back to normal. I noticed that while I was moving at a good rate, my temps stayed normal, but a soon as I slowed down to stopped, that is when my temps would move above normal. I did make it hope, with my heater basting. When I got home, I checked my fluid levels and all was normal
I'm figuring the issue is probably with a fan not kicking over. Any thoughts?
Yes, remove the gauge and you will be a safer driver!
Recent research has shown that cars with fewer gauges and play things (Navi or Internet boxes) have less accidents. Top of the list are cell phones, with the Navi second.
I don't even like warning lights, as they should fit audio alerts, with a bell for get off the road and switch off warnings (Overheat or low oil pressure) and a less obtrusive chime for things like brake light failure etc.
The difference between 197 and 204 is not enough to get concerned about, but if it does start increasing then the thermostat might be forked, as they don't last forever. If you change the water pump every cam belt service and use something sensible, a water pump failure will be very unlikely. Incorrect bleeding of the cooling system is more likely than pump trouble, so if in doubt read the instructions.
