Is A Thermostat Covered Under Warranty

Is A Thermostat covered under warranty? If your car is covered under a manufacturer or factory warranty, repairs are generally covered at no cost to you. However, most manufacturer warranties only last a certain amount of time or mileage, with most standard factory warranties ending at 3 years or 36,000 miles. If your car’s Thermostat breaks unexpectedly and your manufacturer’s warranty expired, then you’ll left paying those costly repair bills on your own.

It’s important to check the warranty information for your specific vehicle before making any repairs. Some warranties may cover the cost of repairs, while others may only cover the cost of replacement parts.

Manufacturer’s Warranty

Thermostat breaks are commonly covered by the vehicle’s Manufacturer Warranty. This coverage typically applies to defects in materials or workmanship during the warranty period. The warranty duration for a vehicle’s Thermostat can vary. It may range from a few years to the vehicle’s lifetime. Check your vehicle’s warranty documentation or contact the manufacturer for coverage period.

Manufacturer warranties frequently include exclusions, such as coverage for typical wear and tear or damage resulting from accidents, misuse, or modifications by the owner. Should your vehicle’s Thermostat break, you can usually get it fixed or replaced at an authorized dealership or service center. In order to secure warranty coverage for your vehicle, proof of ownership is typically required. This can be provided through your vehicle’s registration or purchase documents.

Extended Warranty

Consumers may choose to buy Mopar Extended Warranties to cover Thermostat. These are frequently provided by third-party companies or retailers and can offer coverage beyond the manufacturer’s warranty. Carefully review the policy to understand the coverage and circumstances for repairs under extended warranties.

The Mopar Maximum Care Warranty, also known as the “bumper-to-bumper” warranty, is the most comprehensive extended coverage available for Chrysler, Dodge, Jeep or Ram. It extends your Chrysler, Dodge, Jeep or Ram’s powertrain and basic component coverage beyond the 3-year/36,000-mile manufacturer’s warranty. Additionally, it covers more than 5,000 components, providing virtually complete mechanical coverage for your vehicle.

The only components not covered under this warranty include:

  • Maintenance services and items used in such services.
  • Glass, plastic lenses.
  • Body and paint items, including soft trim.
  • Wear items such as manual clutch assembly, brake pads, shoes, rotors, drums and belts are not covered at any time.
  • Snowplows, winches and trailer hitches

Signs Of A Failing Thermostat

The thermostat in your car, often overlooked but of paramount importance, plays a critical role in regulating the flow of coolant through the engine. Maintaining the engine at an optimal temperature is crucial for its efficiency and longevity. When a thermostat begins to falter, it can lead to severe consequences, such as engine overheating and potential costly repairs. In this extensive guide, we will delve into the nuanced signs of a failing thermostat, providing detailed insights on these issues and how to address them effectively.


Engine overheating, a common symptom of a failing thermostat, occurs when it gets stuck in a closed position due to corrosion or aging. This disrupts the flow of coolant to the radiator, causing a significant rise in engine temperature. On the flip side, overcooling happens when the thermostat is stuck open, diminishing the engine’s overall life cycle. These issues highlight the thermostat’s critical role in maintaining the delicate balance of engine temperature and the importance of recognizing and addressing malfunctions promptly. Regular maintenance checks are key to preventing severe damage and ensuring optimal engine performance.

Coolant Leaking

While a coolant leak is not directly linked to thermostat issues, it acts as a valuable indicator of potential problems within your vehicle’s cooling system. To investigate, closely examine the thermostat housing for drops, drip marks, or deposits. This meticulous inspection is crucial for identifying the source, which could involve a malfunctioning gasket or another component in the cooling system. Pay attention to subtle signs like moisture accumulation, treating the examination as a diagnostic journey to pinpoint and address the underlying issue effectively.

Erratic Temperature Changes and Strange Sounds

Beyond the immediate concern of overheating, a failing thermostat can lead to erratic temperature fluctuations within your vehicle, accompanied by unsettling sounds like rumbling or knocking from the radiator. These audible anomalies are indicative of deeper issues within the cooling system, necessitating professional inspection for a comprehensive diagnosis and resolution.

Seeking the expertise of a professional mechanic is crucial to decipher the complexities of the cooling system and identify the root cause of these irregularities. Attempting DIY fixes without the necessary knowledge may lead to inadvertent mistakes or oversight, potentially worsening the problem. A professional inspection not only addresses the immediate issue but also ensures preventive maintenance, fortifying your vehicle against potential cooling system challenges for sustained reliability and performance.

Heater Problems

In colder seasons, particularly when temperatures plummet, the proper functioning of your vehicle’s heating system becomes paramount for comfort and safety. A malfunctioning thermostat, stuck in an Open Position, can disrupt this crucial system, leading to discomfort and potential hazards. When you find yourself turning up the heater but still experiencing cool air from the vents, it serves as a clear indication of a failing thermostat.

The implications of a malfunctioning thermostat during colder months extend beyond mere discomfort. In extreme weather conditions, inadequate heating can compromise visibility by failing to defrost windows efficiently, thereby increasing the risk of accidents.

Incorrect Readings on the Temperature Gauge

The vehicle’s temperature gauge, designed to provide critical information about coolant temperature, may display incorrect readings in the presence of a failing thermostat. Whether too cold or too hot, these inaccuracies can lead to unreliable warnings or failures to detect overheating, underscoring the need for regular checks and possible thermostat replacement.

Engine Running Inefficiently

A malfunctioning thermostat can hamper your vehicle’s engine performance by allowing excess coolant to enter. Often due to being stuck in an open position. This disrupts the engine’s temperature balance, leading to lower-than-optimal temperatures. The consequences include reduced combustion efficiency, decreased fuel economy, potential lubrication issues, and impacts on the emission control system. Additionally, the irregular temperature regulation can accelerate wear on engine components. Emphasizing the importance of promptly addressing thermostat issues to maintain engine longevity and efficiency.

Leaking Coolant

Improper installation or the wear and tear of a thermostat can lead to coolant leakage, posing potential risks to your vehicle’s overall performance. When you detect coolant leaking around the mounting surface, it’s essential to take proactive measures. Consider starting with a thorough inspection of the thermostat installation. If the thermostat is relatively new, opting for professional reinstallation can ensure proper placement and prevent future leaks. However, in cases where wear and tear are evident it may be prudent to consider a complete replacement. This proactive approach not only addresses the immediate issue but also contributes to the long-term reliability of your vehicle’s cooling system.

Spotting Rust or Clogs

A visual inspection under your car’s hood might reveal a rusty or clogged thermostat. If the thermostat appears compromised, it is advisable to replace it promptly. Using the correct coolant for your car can also prevent damage to the cooling system. It also extends the thermostat’s lifespan, showcasing the importance of routine maintenance.

A failing thermostat poses multifaceted risks to your engine’s performance and longevity. Regular inspections for the signs mentioned above are indispensable. If you suspect thermostat issues, consulting with a professional mechanic is recommended. Timely intervention can prevent severe damage and ensure your engine operates efficiently.

Remember, a well-maintained thermostat is key to a healthy engine. Prioritize its care to avoid unnecessary repairs and keep your vehicle running smoothly.
