Is Thermostat Covered Under Jeep Powertrain Warranty? Explained

When your Jeep needs repair, warranty coverage can save you a lot of money. But not all parts are covered by the same warranty.

Many Jeep owners wonder if the thermostat is included under the powertrain warranty. This is important because thermostats help control your engine temperature, and a failure can lead to overheating or engine damage.

Let’s explore what the Jeep powertrain warranty covers, whether the thermostat is included, and what you can do if it’s not.

What Is The Jeep Powertrain Warranty?

The Jeep powertrain warranty is designed to cover key parts of your vehicle’s engine, transmission, and drivetrain. Most new Jeeps come with a 5-year/60,000-mile powertrain warranty. This warranty is meant to protect the most expensive and vital components.

Here are the main parts covered:

• Engine: Internal parts like pistons, camshaft, oil pump, and timing chain.
• Transmission: All internal parts and the torque converter.
• Drivetrain: Axles, differentials, and driveshafts.

Below is a summary of typical coverage:

You can see the thermostat is not included.

Is The Thermostat Covered?

The thermostat is a small but important part of your Jeep’s cooling system. It helps regulate the flow of coolant to maintain proper engine temperature. If it fails, your engine can overheat and suffer damage.

Most Jeep powertrain warranties do NOT cover the thermostat. The reason is simple: the thermostat is part of the cooling system, not the powertrain. It is considered a “wear item,” meaning it is expected to need replacement during normal use.

Here’s how Jeep divides coverage:

If your Jeep is still within its bumper-to-bumper warranty, you may get coverage for the thermostat. But after this basic warranty expires, the powertrain warranty will not cover it.

Why Isn’t The Thermostat Covered?

Jeep and other car makers limit powertrain warranty coverage to parts that rarely fail and are expensive to fix. The thermostat is inexpensive and easy to replace compared to major engine parts.

Some reasons for exclusion:

• It’s a wear item: Thermostats break down over time.
• It’s not a core powertrain component: The powertrain warranty is for parts that move the vehicle.
• It’s part of the cooling system: This system is not included in powertrain coverage.

This separation is common for most automakers, not just Jeep. You’ll find similar exclusions with Ford, Toyota, Honda, and others.

What To Do If Your Thermostat Fails

If your thermostat fails after the bumper-to-bumper warranty ends, you must pay for repairs. The good news is that replacing a thermostat is not costly. Most shops charge between $100 and $250, including parts and labor.

Here’s what you can do:

• Check your warranty status: See if you’re still within the bumper-to-bumper warranty.
• Ask about extended warranties: Some Jeep dealers offer plans that include cooling system parts.
• Shop around: Compare prices at local mechanics.
• DIY replacement: If you’re handy, you can replace it yourself. The part usually costs $30–$60.

If you ignore a failed thermostat, your engine can overheat. This may cause expensive damage that IS covered by the powertrain warranty, such as cylinder head cracks. But the thermostat itself will not be.

Non-obvious Insights For Jeep Owners

Many Jeep owners miss these points:

• If your thermostat fails and causes engine damage, the damage may be covered, but not the thermostat itself. This can lead to confusion at the dealership.
• Extended warranties are often negotiable. You can ask for coverage of cooling system parts, including the thermostat, when buying an extended warranty.
