Jeep Cherokee Oil Pan Gasket: Diy Replacement Guide

If you're looking to change the oil pan gasket on your Jeep Cherokee, you'll be pleased to know that it's more of a dirty job than a difficult one. While it may seem daunting at first, with the right tools and some patience, it's definitely achievable, even for novice mechanics.

The first step is to disconnect the negative battery cable, jack up the Jeep, and drain the oil. You'll then need to remove the starter and loosen the oil pan bolts before supporting the oil pan with a floor jack. From there, you can remove the oil pan bolts and carefully take out the oil pan. It's important to note that you may need to lower the back half of the oil pan and pull it out from under the transmission, especially if you have stock suspension.

Once the oil pan is out, you'll want to inspect the mating surfaces of the block and oil pan, cleaning them thoroughly. Install a new gasket, making sure to apply RTV to the T-joints for a proper seal. With the new gasket in place, you can then torque the bolts to the specified tightness and reattach the transmission line clip and oil dipstick tube.

While this process may take a long weekend to complete, it will save you a significant amount of money compared to taking it to a dealer or local shop. Plus, you'll have the satisfaction of knowing you did the job yourself!

Jack up the Jeep and drain the oil

Jacking up your Jeep Cherokee and draining the oil is a crucial step in changing the oil pan gasket. Here is a detailed guide to help you through the process:

Park your Jeep Cherokee on a level surface and engage the parking brake. This is important for stability and safety when jacking up the vehicle.

Locate the jacking points on your Jeep Cherokee. The recommended jacking points are the two front support points mentioned in the manufacturer's manual.

Place jack stands at the identified jacking points. Ensure they are securely positioned to bear the weight of the vehicle.

Using a floor jack or a transmission jack, slowly lift the vehicle until it is high enough to slide the jack stands under the recommended jacking points.

Chock the rear wheels and ensure the parking brake is engaged. This adds an extra layer of safety while working on the vehicle.

Once the Jeep is securely lifted, remove the front wheels. This step provides easier access to the undercarriage and the oil pan.

Locate the oil drain plug, typically found at the bottom of the oil pan. Place a drain pan or container underneath to catch the drained oil.

Using the appropriate tool, loosen and remove the oil drain plug. Allow the oil to drain completely. This may take several minutes, depending on the temperature and viscosity of the oil.

Some Jeep Cherokee models may have an oil filter mounted on the oil pan. If present, remove the oil filter at this stage.

After draining the oil, clean the area around the oil pan. This includes removing any residual oil, dirt, or debris that may be present.

Now, you can proceed to the next steps of changing the oil pan gasket, which include removing the oil pan bolts, lowering the oil pan, and replacing the gasket. Remember to refer to a repair manual or seek guidance from a qualified mechanic if you're unsure about any part of the process.

Always exercise caution when working on your Jeep Cherokee. Ensure that the vehicle is securely supported, and never work under a vehicle that is not properly lifted and stabilized.

Remove the starter

To remove the starter on a Jeep Cherokee, you will need to first disconnect the negative battery cable. Next, jack up the Jeep and support it with a jack stand by the frame. Drain the oil and then remove the starter, torquing the front bolt to 30 ft-lb and the rear to 35 ft-lb.

• It is important to disconnect the battery before beginning any work on the starter. This is a safety precaution to prevent any electrical short circuits.
• When jacking up the Jeep, ensure that it is securely supported by the jack stand. This will provide stability and prevent accidental lowering during the repair process.
• Draining the oil is necessary to avoid spills and mess during starter removal. Place a suitable container underneath the oil pan to collect the drained oil.
• Pay attention to the torque specifications for the bolts. The front bolt should be torqued to 30 ft-lb, while the rear bolt should be torqued to 35 ft-lb. This ensures that the bolts are tightened correctly, preventing any loose connections.
• If you encounter any difficulties or complications during the starter removal process, don't hesitate to consult a professional mechanic or seek advice from a Jeep forum or community.

Remove the oil pan bolts

To remove the oil pan bolts, you will need to first drain the oil. Then, remove the starter and the inspection plate. You can then loosen the oil pan bolts and support the oil pan with a floor jack.

If your Jeep is at stock height, you may need to jack it up to gain more clearance. Let the front axle droop by removing the front wheels and placing the Jeep on jack stands. You can also remove the front tires and turn the wheel all the way to the left to allow more room for the pan.

Once you have enough clearance, remove the oil pan bolts.

Remove the bearing cap retainer and rear bearing cap

To remove the bearing cap retainer and rear bearing cap of a Jeep Cherokee when changing the oil pan gasket, follow these steps:

First, you will need to remove ten bolts from the bearing cap retainer. These are likely to be 10mm bolts. Once all ten bolts are removed, you can take the bearing cap retainer off. Next, you will need to remove the two bolts from the rear bearing cap. When these are removed, you can take off the rear bearing cap.

It is also recommended to loosen all the bearing caps to help with the removal of the upper RMS (rear main seal).

Clean mating surfaces of the block and oil pan

To clean the mating surfaces of the block and oil pan, you will need to remove the old gasket residue. This can be done with a gasket scraper, a wire brush wheel attached to a drill, or a small wire brush on a die-grinder. You can also use brake cleaner on a rag to wipe away the residue. If the old gasket is particularly stubborn, you can try soaking it with WD-40 to soften it up.

Once the old gasket has been removed, you will need to clean the mating surfaces with a solvent to ensure that the new gasket adheres properly. Methyl ethyl ketone or acetone can be used for this purpose. Be sure to follow the manufacturer's instructions for the gasket, as some may require additional steps, such as applying a bead of RTV sealant to the T-joints.

It is important to take your time and be thorough when cleaning the mating surfaces. Any residue or contaminants left behind can compromise the seal and lead to oil leaks.
