I've noticed my 2014 C7, recently started to run hot very quickly. Then fan runs strong and cools it off but it takes a while. When convertible top is down I can feel the heat coming underneath the car while I am in city traffic. A/C is not on and when temp is 65-70 degrees outside as soon as car comes out of my garage and driven 5-10 minutes in city traffic at 35-40mph oil temp gauge goes more than it did before... Reasons and remedy ideas?
Before that temp gauge only went that high and that often was during 100F+ summer days and after I drive aggressively and not on a 65F day with 40 mph run...
Could it be a sticky thermostat or....???
That gauge is oil temperature, & is normal temperature range especially if running the car hard & higher RPM's. There is also a pocket gauge for water temp as well.

I know that is the oil temp gauge. What I meant is, that gauge never went to that levels or above during the last year when daily temperatures were around 65-70F.
I wonder what may have causing it. I understand driving her hard may cause that but when I drive like a church lady at 35-40 mph in town it is still getting up there even on those 65F days.
And once that temp goes that high also car engine begins to run hotter too and fan starts working for long time.
Hmmm. Mine always used to be right on 200 mark and maybe just a tad above during winters when I ride aggressively. But during slow moving city traffic speeds it was always 200...
In the past year I only saw the levels where it is on that picture during very hot days, my A/C running and I ride aggressively.
During cool winter or spring days I never witnessed that gauge going that high. But I guess it is OK.
I found that changing the T-stat is surprisingly easy. Drain coolant into a pan. Just turn the valve until you get flow, don't remove it. Coolant comes out in a nice vertical stream so it is easy to catch it all. You only need to drain maybe 1-2 qts. Pull the small hose from the T-stat black plastic housing. Pull the housing and install the new T-stat. If you buy just the T-stat itself it can be tough swapping it out of the housing so it may be worth it to buy the housing+ T-stat as they come preassembled. Reinstall the housing but leave the small hose off. Position it near where it goes or a bit higher. Pour the removed coolant into the reservoir. That disconnected hose lets air bubbles out so the coolant goes in easily. When all the coolant is in, reconnect the hose. Reinstall the pressure cap. Hint, on all the GM hose spring clamps put them back exactly in the position they were in originally. Fit them exactly into the recess they formed in the hose. I had replaced my radiator 3 months ago which wasn't a lot of fun. I was pleasantly surprised how well the T-stat replacement went.
Yes coolant gauge always at 220.. But once yesterday for a short time like 10-15 seconds I saw it moved up to 240 then back down at 220 again...
On the other hand, the Oil temp at that moments were a little over 2 notches above 200 mark which I believe was around 232-233 range. then when I get on the freeway and began to roll at 70 mph it came back down to 215-220 levels..
Is this normal heat?
