Engine Coolant Thermostat Housing Gasket

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.
