How to Change the oil in your 2002-07 Jeep Liberty 3.7L
In this tutorial, we learn how to change the oil in your 2002-07 Jeep Liberty 3.7L. First, go underneath your Jeep and remove the oil plug from the tank. Once you do this, let the oil drain out into an oil pan or plastic container. While this is draining, go to the hood of your car and find where the oil filter is. Once you find this, take out the old one and replace it with the new filter. When the oil is done draining, place the drain plug back on and then fill in the new oil to your Jeep in the hood. Once this is filled up all the way, remove the dip stick to check the level and you're done.
