🔧 Common Thermostat Replacement Issues in Plano

Thermostat Stuck Closed - Engine Overheating

When the thermostat valve sticks closed, coolant can't flow to the radiator. In Plano's summer heat, this causes rapid overheating—often within minutes of driving. Pull over immediately if your temp gauge hits the red zone.

Typical cost: $150-$350

Thermostat Stuck Open - No Cabin Heat

A stuck-open thermostat prevents your engine from reaching optimal temperature. You'll notice weak or no heat from cabin vents in winter, plus reduced fuel economy year-round since the engine runs too cold.

Typical cost: $150-$300

Erratic Temperature Gauge Fluctuations

If your temperature needle bounces up and down erratically on President George Bush Turnpike, the thermostat mechanism is likely jamming intermittently. This can progress to complete failure—don't wait.

Typical cost: $150-$400
