How-tos

Changing your Jeep's oil is a pretty simple job that anyone can do at home in the driveway. Doing it yourself not only saves you a few bucks, but gives you a chance to visually inspect other things on your Jeep at the same time. And when you do it yourself, you can rest easy knowing the job is done right and with the exact parts or fluids of your choosing. Depending on your Jeep, whether you've installed a lifted supsension or not, you may even be able to tackle this job without any jacks and jack stands or driveway ramps. And is some cases you can even do this job without raising your Jeep even if the suspension is completely stock. I'll be using a lift, just to make the job of taking pictures easier, but really all you need for this job is a few hand tools.

What You Will Need

  • 6 quarts of 5W-30 (Preferred) or 10W-30 (depending on the temperature range anticipated before your next oil change)
  • New Oil Filter - Mopar Filter M0-090 (05281090)
  • Ratchet
  • 13mm Socket
  • Oil Filter Socket
  • Drain Pan
  • Shop Towels / Paper Towels
  • --- not necessary - but helpful ---
  • Rubber Gloves
  • Funnel

Instructions

Before working on your Jeep, always park on a level surface, put it in park and set the parking break. It's always a good idea to chock the wheels to be extra safe whenever working under your Jeep.

Before starting to change the oil, run the engine for a few minutes to warm the engine oil. This will help the oil flow easier and quicker.

Owner's Manual

According to the owner's manual, 5W-30 is the preferred oil for both the 4.7L and the 4.7L High Output engines and is best for environmental operating temperatures below 100ºF. If you live in an area that sees outside temperatures over 100ºF then you should use 10W-30.

Step 1 - Remove Oil Cap

1. Remove the oil filler cap to help allow all the oil to drain from the engine better.

Step 2 - Remove Oil Filler Baffle

2. Remove the oil filler baffle from inside the oil filler neck.

Step 3 - Remove Drain Bolt

3. Using a 13mm socket, remove the drain bolt from the bottom of the oil pan.

Step 4 - Drain Oil

4. Allow the oil to drain into a pan. Keep some paper towels close by to clean up any spills or drips and to wipe off any oil that may splash onto your exhaust. After the oil has finished draining, replace the drain bolt and torque to 25 ft lbs. (Hand tightening works perfectly fine for the drain bolt if you don't have a torque wrench.)

Step 5 - Remove Oil Filter

5. Using your oil filter wrench, remove the old oil filter.

The Mopar oil filter illustrates the steps for installing your new oil filter.

Step 6 - Clean Oil Filter Sealing Surface

6. Clean and inspect the oil filter sealing surface to be sure there's no corrosion or debris that may cause a poor seal on the new filter.

Step 7 - Lubricate oil filter seal

7. Lubricate the seal on your new oil filter with a few drops of clean motor oil.

Step 8 - Install new oil filter

8. Install the new filter on to the engine block. Hand tighten the filter.

Step 9 - Tighten oil filter

9. Using an oil filter wrench, tighten the filter 1 more revolution past hand tight.

Step 10 - Refill Oil

Step 10 - Add Additional Quard

10. Using a funnel, refill the engine with oil. The 4.7L engine requires 6 Quarts of oil. If you're using a 5 Quart jug, don't forget to add one additional quart.

Step 11 - Replace the oil filler baffle

11. Clean off and re-install the oil filler baffle that you removed earlier.

Step 12 - Replace oil cap

12. Clean off the oil cap, then lubricate the oil seal on the cap with a few drops of clean motor oil. This will help make removing your oil cap during your next oil change much easier.

Step 13 - EVIC Service Interval

Step 13 - Reset Service Interval

13. The overhead Electronic Vehicle Information Center or EVIC for short keeps track of when it's time to complete an oil change. Be sure to reset the service interval after completing your oil change so you'll be reminded when it's time to change it again. With the Jeep in park (the key can be in the on position with or without the engine running) press the STEP button until the service message appears on screen. Then press and hold the RESET button for a few seconds. The EVIC will beep and reset. The EVIC can be programmed to different service intervals depending on your driving habits by using the MENU button when the Jeep is in park.
