It's exactly 100 degrees in NY. I was on the highway going to work and was in stand-still to 5 mph traffic for 15 minutes. Temp sensor goes off. Car is overheating. I pull onto the grass and pop the hood and look under the car. No leaks or steam (replaced plastic water neck with aluminum last year). Fan was still running with car off. I waited 20 minutes, opened the coolant cap, released some pressure, and saw it was somewhat low, and topped off with 50/50 dexcool. Continued to work another half hour with faster traffic and no overheating.
What are we thinking? Low coolant and high temps caused it with no other broken parts? Fan runs, no leaks... thermostat? Thanks.
