FAQ

Q: Could a damaged thermostat affect engine performance?
A: Yes, a broken thermostat could cause the engine to overheat and lead to engine damage.

Q: Could a damaged or missing thermostat affect fuel economy?
A: Yes, every engine is designed to run at a specified temperature. An engine that runs cold (without a thermostat) may use 10-20 percent more fuel and will not run properly.

Q: Is there a way to verify that my vehicle's thermostat is functioning properly?
A: Yes, the thermostat can be tested by boiling it in plain water for approximately 3-5 minutes. If the thermostat does not open, it should be replaced.

Q: Could a damaged thermostat affect interior heat?
A: Yes, the thermostat can become stuck in the open position. This will prevent the engine from reaching operating temperature in cold weather, resulting in poor interior heater performance.

Maintenance & Troubleshooting

Signs of Wear & Troubleshooting

Signs of wear include:

Coolant leak
Overheating of the engine
Lack of available heat in the vehicle cabin
Reduced fuel economy

Good Maintenance Practices

Maintain proper coolant levels and check level monthly (Note: Never attempt to remove a radiator cap while the engine is hot. Serious injury could result).

Replace coolant with a mixture of antifreeze and water according to the vehicle manufacturer's recommendations.
Inspect engine belts for cracks or missing sections; check belt tension.
Evaluate radiator and radiator cap for leaks, corrosion, or a worn cap gasket.
Examine hoses every 12 months. Look for leaks, cracks or rot. Replace when showing signs of wear.
Tighten any loose clamps. Always replace clamps when replacing hoses.
Have cooling system inspected immediately if instrument panel-mounted temperature gauge indicates engine overheating.
Periodically, remove bugs, leaves and other debris from the front of the radiator. They can block airflow and substantially reduce cooling efficiency.
