When Should You Replace Your Jeep Cherokee Thermostat?

The thermostat functions similarly to a valve that opens and closes in response to temperature. Until the engine reaches a specific minimum temperature, the thermostat isolates it from the radiator. The engine would always lose heat to the radiator if it didn’t have a thermostat, and it would take longer to warm up. The thermostat controls the flow to the radiator to maintain a constant temperature once the engine has achieved the optimum operating temperature.

There are a few signs of a malfunctioning thermostat such as odd temperature readings, abnormal behavior of the air conditioning system, coolant leaks, strange sound, and heater problems.

Odd Temperature Gauge Readings

When you initially start your Jeep, the temperature gauge should read chilly and gradually rise to normal as the engine warms up. It’s conceivable that there’s an issue with the thermostat if the temperature gauge is reading lower or higher than normal. If your automobile is constantly overheating, the thermostat is most likely not flowing coolant into the engine to lower the temperature.

Air Temperature Changes

The temperature of the air that comes into your Jeep through the vents may also be affected by the thermostat. It’s a clue that your thermostat isn’t operating correctly if the air temperature changes from hot to cold or cold to hot. These temperature variations are frequently irregular and abrupt. When you notice these interior temperature variations, it’s critical to get your car evaluated.

Coolant Leaks

When a thermostat malfunctions, it frequently remains in the closed position. Coolant will overflow from the thermostat housing when the engine overheats. This implies that coolant seeping from your engine might indicate a problem with your thermostat. It might also indicate that your radiator hoses, the radiator itself, or the seals and gaskets are faulty.

Strange Sounds

Strange noises are another indicator that your thermostat is failing. Because the coolant is boiling, you may hear rumbling sounds coming from the engine. These sounds might be coming from the radiator. It might also sound like something is cooking or banging. The sound might also be bubbling at times. All of these indicators lead to a cooling system issue.

Heater Problems

Finally, no matter how much you turn up the heater in your car, you won’t have hot air rushing through the vents if your thermostat is locked in the open position. Because we’re swiftly approaching summer, you may not notice this problem right now, but if you had difficulties with your heater last winter, bring your car into our shop for an examination.

Is it safe to drive a Jeep with a thermostat problem?

No. If a thermostat problem has been identified, it should be addressed as soon as possible. Failure to do so might result in serious and costly engine damage.

Can You Replace A Thermostat By Yourself?

Thermostat replacement is a job that should be left to professionals. As a car owner, you may examine your radiator on a regular basis to determine whether it’s damaged and look for the warning signs mentioned before.

When it comes to fixing and replacing it, though, you’ll need the help of a professional.

How To Replace A Jeep Grand Cherokee Thermostat?

Replacing the thermostat of a Jeep Grand Cherokee is a complicated task that includes a few risk. However, for your convenience, I am going to tell you the step by step process of the replacement project-

Required Tools:

  • Socket Set
  • Rags
  • Hose-Clamping Pliers
  • Plastic Scraper
  • Drip Pan
  • New Thermostat
  • Gasket
  • Coolant
  • RTV Sealant

Locate your thermostat. These procedures are for thermostats that are positioned where the top radiator hose connects to the engine. The approach is the same if your thermostat is in the bottom radiator pipe.

Place a Bucket Under the Radiator. Some fluid will leak out, so keep a clean two-gallon container on standby to capture it and restore it to the radiator when you’re done.

Remove the clamp and locate your thermostat by following the radiator pipe.

Pull off the hose. This is when the fluid will start to leak.

Remove the bolts that hold the thermostat housing in place. Compare the old and new thermostats and their gaskets. If the new thermostat and the gasket that comes with it aren’t the same as the old ones, return to the store and get the correct ones.

Put the new gasket in place, remove the gasket that surrounds the hole where the thermostat used to be. Scrape away any trapped gasket parts, but don’t allow them to fall into the hole!

Drop-in and put the new thermostat in place. Make sure to place the spring-side down; then replace the bolts

Pour any fluid that has leaked from the hose back into the radiator fill hole or coolant reservoir from the container.

Is replacing a thermostat difficult?

The thermostat (or T-stat) in an automobile is a simple and affordable repair. It will usually solve an overheating or no-heat problem, saving you time and money on professional diagnostics.


The thermostat is one of those delicate parts of the automobile that is vital to the driver and vehicle’s safety while on the road.

As a result, having a badly kept or malfunctioning radiator increases the chances of experiencing any inconvenience, and the best cure is to replace it with the suitable radiator at the proper time.
