Car maintenance: Don't skip these 8 moves
Don't drive after your car overheats
You can't really put a price on how dangerous it is to drive your car after it overheats. "If your car is overheating and you keep driving, you could end up with a broken hose or head gasket, and your car might need to be towed," Brocoff says.
She says the worst-case scenario would be if you're on a driving vacation or business trip and your car must be towed into a small town.
"You could be stuck for days waiting for the right part to arrive," Brocoff says. "Imagine the cost, not only in stress, but for lodging and food and other expenses while you wait for your car to be fixed."
