This is one of the easiest vehicles and motors to do oil changes on. So if you own one of these, we highly recommend you learn how to do this yourself because it will save you a lot of money in the long run.

Step 1.

Get an oil and oil filter, also it’s a good idea to to get gaskets that go on the oil pan drain plug in case you need to replace that. You will need a 32 millimeter short socket to get our oil filter cap off. Along with that it helps to have a pivoting head on your ratchet.

First step we’re going to do is jack up the vehicle just come right up under the front. And right along here is going to be our jack point we’re going to just locate the center that then on either side support the vehicle jack stands.

So vehicle doesn’t have to come completely off the ground just where you can get up under and get to your oil drain pan comfortably. Get the vehicle supported on the frame rails. If you want, you can also use the pinch weld.

Step 2.

When you’re under the vehicle you can see the bottom of your engine pan. This one over here is your transmission. And that pole there is what we were looking for.


Use a 15 millimeter bolt, you just want to have a drain pan ready to catch any oil that comes out. Loosen that off. And it’s good time to wear gloves if you don’t want oil all over your hands, and just going to go ahead and take it out by hand from now and just catch that oil.


Step 3.

Let that drain out. And as that’s draining, we can go ahead and start to replace the filter up top. So as that’s draining, We’re going to use that 32 millimeter socket. And you can see it is kind of tight in there. That’s why having a pivoting head on your ration will make your life a lot easier. Once you get it loosened off enough, you can just usually go in by hand and finish it. Keeping in mind you are going to have some oil in here. So you may want to have a rag handy so it doesn’t spill everywhere. You just got to be careful that that doesn’t spill all over the place on you, you just going to want to wipe that up. Put the new filter in and hand tight it, and then go ahead and tighten it down to the torque spec.


Step 4.

So back up under the vehicle. Now we’re going to go ahead and just wait for that drip to stop once it does. We just clean up the meeting surface where the bolt is going to go. Then once you got your bolt re installed you can just take the oil pan out from under the vehicle and then lower the vehicle to the ground.

Step 5.

Now we can go ahead and remove our oil fill cap and also on it is the viscosity we need to use. Put the new oil in.

Then use the dipstick to check it and if we need to add any we can usually add at this point.


Step 6.

Once we verify that we have enough oil in there, we will go ahead start the engine, let it run for a minute and then check the dipstick again after it settles for a couple minutes. When you pull the dipstick out, just make sure you clean it completely along that cross hatching section there and then put it back in and then take your reading.
