I just did a round trip of about 110 miles today and had the coolant smell. I have a 2021 Silverado RST Z71 Duramax with about 54k on it. The truck has been from Virginia to Georgia to Alaska -25F to Texas 117F and back to Georgia over its life. Just now about to replace the first set of tires tomorrow. Thread still good just notice cracking on them. Today I saw high 220s temps while driving the above miles once I came off the highway and on the return trip didn’t see more than 212-13ish. This was the second time in almost the same exact manner on a trip in January. I did have to add coolant 2-3 weeks ago and it took almost 3/4 of the bottle. Didn’t look like it needed it but it was well below the minimum cold temp mark. I think I will take it to the dealer but I’m afraid of getting the runaround because I went through the ringer with a dealer with my ZR2 Bison Colorado to the point GM made them buy the truck back. There’s no codes other than the occasional emissions one that happens on these trucks and I always just clear it with my scan tool. So there’s nothing other than the smell and the slightly high temps.
