What's involved

What this repair actually is.

We check coolant level and condition, test the thermostat, radiator, cooling fans, water pump, and hoses, and monitor live engine temperature data to pinpoint why the engine is overheating. Overheating has many possible causes, so testing first prevents paying for parts you don't need.

Symptoms

How you can tell.

  • Temperature gauge climbing into the red
  • Steam coming from under the hood
  • Sweet smell from the engine bay
  • Heat gauge spikes in traffic but settles on the highway
  • Low coolant warning light keeps coming on
  • Heater blowing cold while the engine runs hot
If you delay

Driving an overheating engine can warp the cylinder head and blow the head gasket, turning a small repair into a major one.

Educational estimate. Real pricing depends on your vehicle, the inspection, parts availability, taxes, and shop rates. Use this as a guide while you shop quotes.
