Jeep Liberty owners with a 3.7 liter engine have reported issues with head gasket failures due to overheating, stemming from coolant loss linked to engine oil conditions. Many drivers have noted discovering a "brown sludge" in the oil filler neck instead of clean oil. Another common problem is a small crack that often forms on the drivers side upper tank of the radiator, leading to antifreeze leakage into the engine. This leak can damage engine components like bearings and ultimately cause head gasket failure. If left unchecked, it may require replacing the entire engine. The average cost for repairing a head gasket on the Jeep Liberty ranges from $990 to $1,200 for parts and labor.

Could you let me know the mileage on the vehicle and whether it has received routine maintenance?

I've owned two Jeep Liberties, while my brother had one. One was a 2005 model, and the other two were from 2010. Unfortunately, all three of these Jeeps experienced a blown head gasket issue. It's no wonder they stopped producing them. I certainly won't be getting another one!

About a month ago, my 2008 Jeep Liberty began experiencing issues. The check engine light would turn on, and it felt like there was a problem with the fuel injector. However, the next day things would be normal, and the light would turn off. I'm wondering if this could be related to a sensor or spark plug problem. Additionally, a new issue has arisen where the car makes a ticking noise while idling.

Someone attempted to provide a full estimate for replacing the engine after the passenger side head gasket blew. However, upon inspection, it was revealed that the engine had already been swapped out with a secondhand one before I made the purchase.

To the person who mentioned their engine making a ticking sound, be sure to check the oil level. Some engines use synthetic oil that can evaporate, so switching to conventional oil might be a better choice.

Jeep was taken to the shop because it was overheating. The garage replaced the thermostat and water pump, but they mistakenly installed the thermostat upside down. As a result, the car continued to overheat. Upon investigation, it was found that the thermostat was upside down. After correcting the installation, it appears that the head gasket may now be leaking due to the previous overheating. The discussion now is what the garage should be responsible for. Should they install a new or used motor, considering the car has high mileage?

Hey Howard! Are you wondering if the 2 blown Liberty head gaskets are on the driver's side or the passenger's side?
