Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
Raise and support the vehicle. Remove this under shield that goes under the transmission and transmission. There is some 10 millimeter bolts here, and then two here. We'll remove those. Use a 10 millimeter socket a long extension and my ratchet. Just so I don't have to reach up here, but you can use any length ratchet. These two bolts were so rusted they broke. There's plenty of plastic clips holding this tray on. I'm not worried about it.
These bolts are also very rusty along here. One of them already broke, so what I'm going to do is remove all of the clips and then fold the plastic under tray down to get it out of the way. I'm going to leave these bolts in place. Not touch them. If your vehicles not rusty, they'll probably come out without a problem. This car is very rusty. They're going to break on us. I'm not going to bother with it. I'm just going to use a flat bladed screwdriver to release these plastic clips. Pop them out.
Once you get them started, you can use a trim clip tool. I've just gone along and found all the push clips holding this up. Somebody has already cut this to give them better access to the oil pan and the oil filter. So normally they'd probably be a door here you'd flip down. Ours doesn't have it. I'm not going to worry about it. There's one more clip here. I'm just going to take a bungee cord, just hook it to this, and you can hook it to the front grille. That'll just help hold it out of the way.
Got a drain pan in place. Going to loosen our drain plug. It's a 14 millimeter. Break it free. So this one is not looking so good. It should be a dark black color or caramel color. This is like a milky, chocolatey kind of mocha color. That's tell me there's probably coolant in this oil. It's likely this engine has a bad head gasket, which is unfortunate. That's a pretty good sign your head gasket is leaking, and you've got coolant contaminating and mixing with the oil, which is very bad. Its ruins the bearings and engine. We're going to change this oil for now, but this engine will need a head gasket.
It's draining pretty well. I'm going to reinstall the plug. The gasket stayed in place, so I'm just going to tighten this up. Threads in this plug aren't great. Somebody might have started to cross-thread it. Should spin in nice and easy. You want to over tighten it until you feel it stop. That's perfect.
Now I can remove the oil filter and put some fresh oil in it. Push an oil filter wrench. This one is 65-68 millimeter. Fits over the end of the plastic cap pretty well. Have our drain pan ready. Spin this free. Get this out of the way. This is stuck in place. You want to carefully hit this tab. Break it free. Use some adjustable pliers on here. The filter is a cartridge type. It's going to come out of the plastic cap, then get thrown away. We got our oil cap where the oil filter goes into. There's a rubber O-ring that needs to be replaced. We use a pick to pull it out. Throw that away for now.
Push on the O-ring. This is pretty oily so it'll slide right over it. Slide it into the groove. Put oil around it. I'm just going to wipe this out. Get some of the old oil out of here. Take the new cartridge filter. It pushes in place. Then this will get reinstalled. We'll thread it in. Just going to tighten the cap by hand. Get it until it's seeded. There's still a gap here. I'm going to turn it til this black plastic is touching the aluminum. That should be tight enough. I don't want to over tighten it. That'll get it nice and tight by hand. That should be good. Wipe up some of the oil. You're all set.
Going to take this bungee cord off, flip the plastic under tray back up. I'll catch these back ones first. Just reinstall all the clips you removed to get the tray off. Open the oil cap. That should tell you the weight of the oil. 0W-20. The funnel doesn't fit that well, you can pop this cover off very easily. Just pops off the three rubber plugs that it sits on. The cover is broken, but it goes like that. Since I can get to that easier, put the funnel in. Pour in four quarts, and then I'll check it. Make sure it's enough oil.
To check the level, pull the dipstick. Wipe it off. Hopefully this is enough time so that the oil run down into the oil pan. It's going to be dark to see, because it's very clean and clear but the edge of it, so the low mark would be that point there. The high mark would be here, and it's right about there so it needs I'd guess about half a quart more. Double check the oil level again. So it's really hard to see because the oil is so nice and clean, but it's right at the top mark so the oil level is perfect. Put the dipstick back in. Take the funnel out. Actually reinstall the cap before you put the engine cover on. Engine cover simply pushes into place just like that. You're all set. You can close the hood.
