Question: what is wrong with my car if my radiator overflow tank started spraying coolant?

When I was 90% of the way to the West Coast fron the East Coast my radiator overflow started spraying out coolant antifreeze after I drove through the rocky mountains. This happened twice. The first when I was idling at a gas station waiting my turn in line to fill up and the second when I was going up a 2 mile climb up a mountain. My radiator does not appear to be leaking at all as there are no puddled under my car. On both occasions the engine temperature was completely normal. I choose not to do anything about it and just monitor the situation for now. It's been two months and it has not happened again. What actions should I take?

I would start by replacing the radiator cap, and have the overflow tank overflow hose checked for obstructions. You may have only had the problem because of the altitude change, but a bad radiator cap could also cause something similar.

It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
