 That's one thing you don't want to do. So always look at that overflow bottle. Basically, if you're not sure, just take it into one of our locations and have one of our technicians look at it. Okay. I mean, you're right, John. It could be maybe the water pump's going bad. Maybe you got a small leak and the cooling system's low, and that's why it's getting hot. Yeah. Could the engine catch on fire if it overheats?
