Common Symptoms

- Heater suddenly blowing cold air
What This Could Mean
Overheating is almost always a cooling system problem — but the cause varies. It could be a coolant leak, a stuck thermostat, a failing water pump, a clogged radiator, or a head gasket issue. Overheating in traffic points to airflow or fan problems. Overheating at highway speed often means coolant flow is restricted. If you keep driving an overheating car, you risk serious and expensive engine damage. Pulling over early is always the right call.
Why Testing Matters
Overheating has multiple possible causes that look similar from the outside. Proper diagnostics identifies the exact failure point so the correct repair is made — preventing further engine damage and unnecessary parts replacement.
