Hey guys so I have a 2019 Silverado 1500LD with a 3.42 rear end with 11k on the clock. I've been noticing that my engine or coolant temp goes passed 210F but when it hits the next 1/8 gauge stick it goes back down passed the middle mark to 190°F. Is that normal for 7000 pounds uphill towing in 95°F weather. Talking about the 5N grapevine in Cali for those who know the climb.
