6 Reasons Why Your Jeep Liberty Gets Overheat: How to Fix?

The jeep Liberty’s engines are typically built to be durable. But when the heat generated by a vehicle’s motor is above the normal operating temperature, the devices designed to cool this heat distribution may begin to fail. Which potentially causes permanent damage not only to the engine, but also to the gaskets, hoses, and seals that are designed to keep the engine running.

Cooling system leaks, clogged hoses from corrosion and mineral deposits, radiator difficulties, or malfunctioning water pumps are all possible causes of your Jeep liberty overheating.

Inspections regularly may help you avoid jeep grand Liberty overheating problem in the future.

How To Diagnose Jeep Liberty Overheating? Problems And Symptoms)

Here are the most common symptoms of Jeep Liberty Overheating.

Temp Light:

A temperature warning light will be included with your Liberty.

The temperature light turning on is the most typical indicator of overheating. If this light does come on, make sure you exit the road safely and promptly.

Overheating can result in long-term engine damage if you drive while it’s hot.

White Smoke:

If the engine in your Liberty gets hot enough, the coolant will boil over and steam will emerge from beneath the hood. It accomplishes this to relieve strain on the cooling system before it suffers permanent harm.

Blown Head Gasket:

The head gasket may blow if your Liberty is run for an extended period while overheating.

White smoke from the tailpipe, a rough idle, and oil in the coolant are all signs of a damaged head gasket.

This is generally avoided by shutting down before it overheats, or as soon as you notice it is overheating.

What are the Reasons for Jeep Liberty Overheating?

1. Too little or no coolant

The most common cause of overheating in your Liberty is a lack of coolant. Low coolant is a sign of a leak in the cooling system.

It doesn’t just vanish on its own. Here are a few reasons why your coolant may be running low:

  • Radiator Damage
  • Bad radiator hose
  • Bad radiator cap

A radiator leak can be found in a variety of places. Make sure you don’t remove the radiator cap while the engine is still warm.

Solution: Unless the coolant is leaking from the cap itself, you shouldn’t need to remove it at all. Because the coolant might evaporate before it has a chance to manifest itself, a gradual leak can be more difficult to locate than a sudden leak.

If you’re losing fluid but can’t tell where it’s coming from, a UV dye can help you find it. It is quite effective. Take a check at the back exhaust if you can’t discover anything with the cooling.

Is there a lot of white smoke in your house? That’s a dead giveaway that your head gasket has blown. You need to change/replace it.

2. Cooling system leaks

Coolant, as we all know, is the fluid that circulates through the radiator and lowers the temperature. The coolant in a well-functioning car would significantly aid in preventing the vehicle from overheating.

Check the coolant level in the expansion tank and fill it to determine whether your engine has a coolant leak, and then monitor the level to see if you’re losing fluid.

Once you’ve determined that the leak is coolant, you may start looking for the source. There could be a hole in the radiator or could be a leaky radiator cap that makes the cooling system leak.

Solution: Replace the damaged hose clams and the radiator hose. Check if there’s any leak on the radiator cap and change it. It should not be costly.

3. A broken water pump

The Liberty’s engine auxiliary drive system turns the water pump in your automobile. The water pump’s speed increases as the engine’s rpm rise. The water pump turns slowly when the car is idling.

Solution: A water pump that isn’t working properly is inefficient.

The water pump is unable to transfer coolant through the radiator and back to the engine while the automobile is overheating while idling.

Put the car in neutral or park and crank the engine to roughly 1000 RPM below the redline for a few seconds to test this.

As the water pump spools up, the temperature should drop. It’s just as difficult to replace a water pump as it is to get to it. This, depending on where you are, can be a breeze or a complete disaster.

4. Radiator issues

An overheated automobile is typically the result of a faulty radiator.

Fortunately, rather than replacing the entire radiator, you generally just need to fix pieces of it. It might be a simple internal clog or an obstacle from the outside, such as debris in the radiator fins.

Radiator fans can break down over time, causing the jeep to overheat due to a lack of cooling.

If your radiator is leaking, you may repair it with a stop-leak fluid solution. There’s also the possibility that the hose is leaking.

Solution: Hoses, fortunately, are typically simple and inexpensive to repair. If a complete replacement is required, schedule an appointment with your mechanic as soon as possible.

Continuing to drive a car with a damaged radiator might cause more damage.

5. Bad electric fan

If the coolant level looks to be normal, the fan is the next easy item to inspect. When the radiator becomes too hot, most automobiles employ electric fans to cool it down. When the car is idle, these fans are very helpful. These fans are prone to failure.

Solution: Open the hood and check if the fan is spinning while the engine is heated and idling. If it doesn’t turn at all, you’ve got a faulty fan. Check if the fuse and fan relay are receiving electricity. If they are, the fan must be replaced.

6. Thermostat failure

The thermostat is next on the list. The thermostat in your Liberty regulates when coolant enters and exits the engine. It’ll either be the water pump or the block.

Solution: Determining whether or not a thermostat is defective without changing it might be difficult. Is it hot in the car after a few minutes of driving?

 That might be enough to indicate that the thermostat isn’t fully open. When an engine is full of coolant, it takes a long time for it to overheat.

You’ll have to replace it, which is a 2/10 mechanical challenge. You’ll probably only need a ratchet, an extension, and a 10mm socket.

Tips To Prevent Your Jeep Liberty from Overheating:

Following a few simple driving precautions will help you avoid permanent engine damage down the road.

  • Check the coolant level in your jeep regularly.
  • In your trunk, have an additional bottle of fresh antifreeze and a gallon of water.
  • While driving, keep an eye on your Jeep’s temperature.
  • On particularly hot days, don’t overdo your Jeep’s air conditioning.
  • At the first sign of overheating, turn on the heat to assist in cooling the engine.

Keep up with coolant servicing flushes by consulting your vehicle’s owner’s handbook.

Final Words

An overheated engine indicates a significant problem.

Regular maintenance inspections will enable you to detect problems early on before they do irreversible harm to your Jeep Liberty.
