Owners of the Jeep Liberty equipped with a 3.7 liter engine have complained of head gasket failure due to overheating. The overheating is caused by a loss of coolant that is related, among other things, to engine oil conditions. A common complaint of 3.7 owners includes finding a "brown sludge" in the Liberty's oil filler neck where healthy oil should be. The radiator often develops a crack in the drivers side upper tank. It is usually small and almost not discernible to the naked eye. Over time antifreeze will leak from the Jeep and into the motor, destroying engine bearings and causing the head gaskets to fail. If not intercepted early, the entire motor may need replaced. The average cost to repair a head gasket on the Liberty is $990-$1,200 in parts and labor.

I have had 2 Jeep Liberty’s, my brother one. One was 05, other 2 were 2010. All these Jeeps had a blown head gasket!! I guess that’s why they don’t make them anymore. You can bet I won’t!!

How many labor hours does it take to replace a head gasket?

For starters, most head gasket jobs require 3-8 hours depending on the how your car is built and what the disassembly and reassembly procedure is. This labor cost is where most of the expense come from for your head gasket job. On top of the labor costs, you have to add on the replacement parts required for the job.

How long does it take to replace a head gasket on a v6?

Replacing the gasket can take anything from six hours to a few days, depending on the severity of the failure. A blown head gasket is one of the biggest failures your car can suffer, and to fix it properly takes time.

Can you replace a head gasket without replacing engine?

Repair Options If your car can run safely for longer than 15 minutes without overheating, there are chemical repair products designed to seal the leak without the need to disassemble your engine. In fact, even those with hardly any mechanical knowledge can install the fix themselves.
