What to Do Right Now

PULL OVER IMMEDIATELY. Turn off the engine to prevent heat damage. Do not open the radiator cap while the engine is hot — pressurized coolant can cause severe burns. Wait for the engine to cool (1-2 hours), then check the coolant reservoir level. If low, add 50/50 coolant mix and look for leaks. The Encore's water outlet housing is a known failure point — if it's leaking, the vehicle needs to be towed to a shop.
