If you do not have a digital temperature display if you are trying to derive temperature from the analog gauge, that is fraught with peril. The analog gauge is dampened and based on my experience over the years with various cars only suitable to know if the engine is cold, warm or hot -- up to temperature hot. An over temperature condition is really signaled by one (or more) warning lights.So after driving around more:
Once I get off the interstate into stop and go traffic the coolant temp will slowly increase. So far I’ve seen increase to 226 (which is still the halfway mark). But when this occurred the first time it went above 226 I assume because the gauge was above the halfway mark.After disclosing some of the problems with the dealership I bought I from, out of good faith they are going to allow me to bring it in and they will take a look at it for free.
Do your temperature gauges ever rise above halfway? Today, being a significantly hotter day than usual (110 degrees), rose above the halfway mark and was stuttering. It never rose enough to where it warned me, and it only rose when I was stopping and going.
I know this could be a faulty fan or temp sensor, but I’m wondering if this is a normality when it is significantly hot as it was today.
I appreciate everyone’s help!
The "flicker" I think the OP is referring to -- and what I have observed -- is with some cars while there is the old fashioned analog temperature gauge -- even my 2018 Hellcat has this -- one can cause a coolant temperature gauge to be displayed between the tach and speedo. This gauge is "graphical" in that it is rendered by LCD display elements and has a guage face with an animated needle. The temperature is provided by this "gauge" but also digitally.Mine does not flicker when hot....its just below the halfway hash mark as always since day one. Find the temp sensor and have someone inside watch the analog gauge and you wiggle the lead.....might be time for a new one because the harness is faulty in his weather conditions due to lead expansion.
