Underneath the engine, you will see a circular machined and finned disk with a nut in the center, that is the oil filter housing the magnetic drain plug is to the side of this filter molding. When you take out the drain plug clean the metal debris off before refitting and use a new copper or fiber washer. Hope this helps good luck.

Below is a diagram for you but I was unable to find a part number for you. Hope this helps.

2006 uplander, there maybe a cover to remove to get to the oil pan, lets see if i can find a picture of the drain plug.okay im not sure the engine size in this uplander but they all should be about the same, here are some diagrams to help you locate the oil filter and oil pan drain plug. the oil filter is located from under the engine on the driverside behind the ac compressor, the oil drain plug is located on the bottom of the oil pan on the pass/side. heres a diagram of the two . hope this helps.

if you could upload a low definition picture i would appreciate it as then i could no doubt tell you exactly what you need to know .

your oil pan is located right under the motor. When your oil is drained and you take out the drain plug that is your oil pan.

you probably won't need a diagram. If you know where the oil pan is. Under the car. There is the oil pan and it has a plug. Put an oil change container under it and remove the plug with a wrench. Let the oil drain out. Replace the plug.You should replace the oil filter too with each oil change. Then after replacing the plug and installing a new oil filter. Put in 4 quarts of oil into the engine by removing the oil cap on top of the valve covers. And your done. check the oil after running the car a while to see if it does not need more oil. Do NOT OVERFILL!! That can ruin the gaskets and an oil leak can occur. I hope this helps you. You can go to autozone .com if you need more info. Just click on the DIY and repair guide.

the exact location is the bolt that sticks out of the bottom of oil pan

Looking at the engine from the front end (e.g. from the right fender), the drain plug is on the left below cylinder #1.

From beneath the car, looking towards the front of the vehicle, you'll find it on the right had end of the engine block, at the back (nearest the passenger compartment. (see image below)

You'll need a 17mm wrench or socket.

The Oil filter is above it and towards the center of the block.
