By | May 5, 2019

I am changing the oil on a 2002 Dodge Dakota with a 3.9-liter engine. For this repair, I chose the S16 STP brand oil filter, and the STP 5W30 STP oil.

One … Slide the drain pan under your truck, placing it under or near the oil pan. Using a 16 mm wrench, loosen the oil drain bolt counterclockwise and remove the bolt.

Allow the oil to continue to drain while we go to the next step.

Two … Using a oil filter wrench (I like the open ended style for this truck, because there is so much in the way and the wrench will need to be on a bit of a angle) loosen and remove the oil filter.

Three … Dispose of the old oil filter. Using oil from your hand, or old oil from the pan, wipe some of it on your new filter seal. This will help it from drying out and leaking.

Four … Replace the new oil filter hand tight plus about a quarter turn.

Five … Now that your oil filter is secure, your oil should have completely drained by now. Replace your drain nut and tighten securely with your 16 mm wrench.
