So yesterday I’m driving my roadster about 30 min all seemed fine stopped at auto parts store for about 10 min, within 5 min of leaving temp was 250, stopped immediately and found fan relay was out. Engine sounded fine, no coolant leaks or steam anywhere , oil looks good, not absolutely sure it wasn’t hot before I stopped at the auto parts store, but I know it was working at some point as I saw temp stabilize after it reached 195 on the way there. Did I do any damage?
