How To Fix Jeep Liberty Overheat Problem

Here are all the reasons why your Jeep Liberty overheats with its particular solutions.

Lack Of Coolant

Lack Of Coolant

The primary cause of Jeep Liberty engine overheating is the coolant issue. Either your vehicle is low on coolant, or there is no coolant. This can happen due to leakage in the coolant system, such as:

  • Damaged Radiator
  • Broken radiator hose
  • Broken radiator cap

Any place of the radiator can contain the leakage. Be careful to remove the radiator’s cap only after the engine completely cooldowns.


You only have to remove everything from the radiator if you see the coolant leaking from the cap. That is because the coolant might evaporate. And gradual leaks are hard to find than gradual leaks. You can use UV dye to determine where the fluid is leaking from.

Check the exhaust if you still don’t find anything with the fluid. And if you see smoke coming out of the hood, you know that the head gasket has blown. So change the gasket to fix the problem.

Leak From the Cooling System

The coolant circulates throughout the radiator of the Jeep Liberty and reduces the engine temperature. It is an essential component for keeping the vehicle from getting overheated. You need to check the level of coolant inside the expansion tank regularly.

Fill the expansion tank to determine if the engine has a leaking coolant issue. Keep track of the coolant level to notice if the fluids are leaking. After you have confirmed the coolant leaking, you need to find the source. A hole in the radiator or broken radiator cap can cause a leak.


Change the radiator hose and the broken hose clams. Also, change the radiator cap if you find the source of the leak there. The cost will be cheap. So don’t worry about the price.

Faulty Water Pump

Faulty Water Pump

The engine of the Jeep Liberty’s auxiliary drive mechanism turns the vehicle’s water pump. When the engine RPM rises, the water pump’s speed also slows down when the vehicle is idling.


A faulty water pump is ineffective for the Jeep Liberty engine. The problem occurs when the vehicle starts idling while being overheated. Thus, the water pump will be unable to transfer the coolant back and forth with the engine and radiator. The solution is simple.

Put the vehicle in park or neutral and turn the engine up to nearly 1000RPM below the redline. Do this only for a moment. The temperature will drop because of the water pump. But the problem occurs when you have to replace a water pump. Take the help of an expert to replace the water pump in this case.

Radiator Problems

The radiator is at the heart of a vehicle’s overheating problem. Instead of replacing the radiator, you can fix a few parts and get on with it. The usual problem is that the radiator has an internal clog or external debris stuck inside the fins.

As a result, the Jeep Liberty will quickly overheat if the radiator fans break down. Stop-leak fluids are a solution for repairing the leak, and the radiator hose can also leak.


Fixing hoses are straightforward and cheap. If the hose needs replacing, delegate the job of replacing the hose to a mechanic as quickly as possible. After all, driving around with a broken radiator can cause long-term damage.

Broken electric fan

If you find the coolant levels normal, check the fans next. If the radiator gets too hot, the electric fans are turned on by the Jeep Liberty. However, the fans will only work if the Jeep is active, and these fans become faulty quickly.


Take a look at the fans after taking off the hood. See if the fan keeps spinning although the engine has gotten idle and heated. If the fans are completely off, the fans are broken. Check on the fuse and see if the fan relay is getting electricity. If not, you will have to change the fans.

Broken Thermostat

Broken Thermostat

The Jeep Liberty’s thermostat regulates the coolant’s entry and exit in the engine. A broken or blocked thermostat can cause problems with the thermostat.


Knowing if the thermostat is broken is necessary to decide to replace it. If you notice the vehicle getting hot after driving only for a handful of minutes, that can only mean one thing; the thermostat is partially open.

If the engine were filled with coolant, it would take more time to overheat. Replace the thermostat, which is relatively straightforward. Use a ratchet, a 10mm socket, and an extension to replace the thermostat.
