The oil drain plug is at the rear of the oil pan, not on the bottom

If you are looking to drain the oil pan of your 2007 GMC Yukon, you may be searching underneath the truck for the oil drain plug, but to no avail. This is because the oil drain plug is at the rear of the oil pan, not on the bottom. The plug will be the same color as the oil pan—a silver-grey color. The size of the wrench that fits it is 13mm.

As the plug can be tight, it is recommended to use a 6-point socket or box wrench so you don't round off the hex of the drain plug.

The plug is silver-grey, the same colour as the oil pan

If you're looking to drain the oil pan of your 2007 GMC Yukon, you'll first need to locate the oil drain plug. This can be tricky, as it's not located on the bottom of the oil pan, but rather at the rear of the pan. The plug will be silver-grey, the same colour as the oil pan, and will require a 13mm wrench to remove. It's important to use a 6-point socket or box wrench when removing the plug to avoid rounding off the hex of the drain plug. Once you've located the plug, simply remove it and allow the oil to drain from the pan. Be sure to have a container ready to catch the drained oil, and be prepared for the oil to be very hot if it has been running recently.

When it comes to replacing the oil plug, it's important to get a tight seal to prevent leaks. You can do this by using a new gasket or washer with the plug. Make sure the plug is tightened securely, but be careful not to over-tighten it as this can damage the threads or strip the plug.

Remember to dispose of the old oil properly and recycle it if possible. Used motor oil can be highly toxic to the environment, so it's important to handle it with care.

If you're uncomfortable performing this task yourself, you can always take your vehicle to a trusted mechanic or service centre to have the oil changed for you. They will have the necessary tools and expertise to get the job done quickly and safely.

Use a 13mm wrench to remove the plug

To drain the oil pan of a 2007 GMC Yukon, you will need to locate the oil drain plug. This can be found at the rear of the oil pan, not on the bottom but at the back of the pan. It will be the same colour as the oil pan, a silver-grey colour. To remove the plug, you will need to use a 13mm wrench.

It is important to use the correct size of the wrench to avoid rounding off the hex of the drain plug. A 6-point socket or box wrench is recommended to avoid this. The plug can be tight, so an appropriate tool is necessary to ensure a quality seal when replacing the plug.

When removing the plug, it is also essential to have the drain pan ready to catch the oil. The oil may come out with some force, so it is advisable to hold the plug in place as you unscrew it. You may also want to wear nitrile gloves to protect your hands from the oil.

Some people choose to use an impact wrench to remove drain plugs, but this is not recommended as it can result in oil covering your tools and yourself. Using a regular combination wrench or ratchet is a safer option and will help you to control the removal process better.

By following these steps and using the correct tools, you can successfully remove the oil drain plug from your 2007 GMC Yukon.

A 6-point socket or box wrench is recommended to avoid rounding off the hex of the drain plug

When changing the oil in a 2007 GMC Yukon, you will need to remove the oil drain plug. This plug is located at the rear of the oil pan and will be the same colour as the oil pan, a silver-grey colour. The size of the wrench that fits it is 13mm.

To avoid rounding off the hex of the drain plug, a 6-point socket or box wrench is recommended. This is because a 6-point socket has a hexagonal shape with six points, evenly spaced at 60-degree increments around a circle. This shape allows for more surface contact area with a six-point fastener, such as the drain plug on the GMC Yukon. The increased surface contact area reduces the likelihood of slippage and rounding over of the corners of the fastener.

A 12-point socket or wrench, on the other hand, has 12 points spaced at 30-degree increments, forming a double-hexagon shape. This shape can also fit a 6-point fastener but will have less contact and offer less torque. Therefore, when working with a 6-point fastener, such as the drain plug on a 2007 GMC Yukon, it is best to use a 6-point socket or wrench to avoid rounding off the hex of the drain plug.

The oil pan gasket should be replaced at every oil change

To replace the oil pan gasket, you will need to obtain the appropriate oil pan gasket replacement. Gasket materials vary depending on the type of metals they are intended to seal. Name-brand gaskets come with any necessary sealants.

• While the oil is draining, remove the splash shield and bellhousing cover.
• For front-wheel-drive vehicles, the oil pan is often mated to the transaxle. Other accessories such as the exhaust manifold support and air-conditioning bracketry might need to be detached too.
• A service manual can help identify all oil-pan bolt locations. Some might be obscured behind other parts.
• Remove all bolts. If necessary, tap the oil pan lightly with a mallet to break the seal.
• Scrape off any gasket residue and clean all sealing surfaces with a solvent.
• Clean the inside of the oil pan and inspect it for cracks.
• Install the new gasket per its instructions. Some gaskets use regular grease to hold them in position.
• Use thread sealer, if specified, then torque the oil pan bolts to spec in a spiral pattern, beginning in the center.
• Reattach any accessory brackets, refill the crankcase with oil, start the engine, and inspect for leaks.

It is important to note that removing the oil pan can be tricky. Attempting to pry the pan loose with a screwdriver can bend the mounting surface, and tapping it with a mallet can crack the pan if all bolts are not removed. Always double-check the bolt count and locations in the manual if the pan does not release easily.
