Replacing Oil Pan In A 2008 Cobalt: Step-By-Step Guide

Changing the oil pan on a 2008 Chevy Cobalt is a complex process that requires a range of tools and mechanical know-how. It is important to note that there are risks involved in this process, and it may be more appropriate to seek professional assistance. However, for those confident in their abilities, the first step is to drain the engine oil. This is followed by removing the engine drive belt and the lower AC compressor bolt. The oil pan bolts can then be removed, and the oil pan itself can be taken off. It is crucial to be aware of any hidden bolts and to ensure that all of them are removed before attempting to take off the oil pan. When reinstalling the new oil pan, it is important to clean the mating surface and apply a bead of RTV sealant. The oil pan bolts should then be tightened to the specified torque value, and the engine drive belt and AC compressor bolts should be reinstalled. Finally, the engine oil can be refilled to the proper level.

Drain the engine oil

To drain the engine oil, you will need to place a drain pan under the bolt at the lowest point of the bottom of the motor. Turn the bolt all the way out and let the oil drain out. You will need to drain all the oil out and then re-measure the amount of oil you will be putting back in. Place 3.5 litres back in as the filter can hold almost half a litre.

Remove the engine drive belt

To remove the engine drive belt on a 2008 Chevy Cobalt, you will need the following tools: a flat-head screwdriver, a 7mm socket, a 10mm socket, an 18mm socket, a 15mm socket, and a 3/8 drive breaker bar.

First, jack up the car on the passenger side and remove the tire. Place a jack stand on the sub-frame to support the car. Remove the inner fender that attaches to the front bumper. To do this, use a 7mm socket to remove the bolts and push the clips. Remove the lower splash guard in the same way.

Next, take your jack and a block of wood and place it under the oil pan to support the engine. Jack up the car until the wood touches the bottom of the pan. Once you feel contact with the pan, jack it up just a little more to ensure the engine is supported.

Now, remove the engine mount. The two outside bolts are 18mm, and the three inner ones are 15mm. With the engine mount removed, you will finally have access to the drive belt. Take your 3/8 drive breaker bar and insert it into the tensioner from the top side. The tensioner has a little square hole in the middle.

From the underside of the car, you will need a second pair of hands to help you remove the old belt by slipping it off the pulleys. Make sure you remember how the belt runs. Match up the old belt with the new belt to ensure they are the same size.

Once you are happy that the belts are the same size, install the new belt in the same way that you removed the old one.

And that's it! You've successfully changed your engine drive belt.

Remove the AC compressor bolts

To remove the AC compressor bolts of a 2008 Chevy Cobalt, first, loosen the passenger-side lug nuts, jack up the car, and put it on stands. Block the rear wheels, engage the parking brake, and remove the passenger-side wheel. Remove the inside splash guard and the plastic retainer plugs holding the splash guard in place. Remove the plastic retainer plugs by taking a pair of dikes or wire cutters, closing them halfway, and using the end to grab the inside plastic piece of the retainer plug. Pull out the retainer and remove the splash guard.

Next, remove the plastic splash guard covering the drive belt. Then, remove the drive belt by pulling back the tensioner arm. Put a 3/8-inch ratchet in the square hole on the tensioner arm to release the tension on the belt and take the belt off.

Now, get under the car and drain the oil. Start to bust the pan bolts loose. There are many bolts, and some are hidden between the casting journals. Look around carefully with a light. There are some 13mm bolts, one 13mm nut, and four or six large bolts that go sideways through the pan towards the driver's side of the engine. After removing all the bolts, tap the pan with a hammer. If it doesn't start dropping, you may have missed some bolts.

Before completely dropping the pan, pop the hood, remove the oil fill cap, and take off the plastic motor cover. Remove the intake tube hose clamp and the plastic intake. Look for the dipstick tube, follow it down to where it bolts to the intake manifold, and remove the nut. Then, remove the wire harness that is clipped to the dipstick tube. Finally, lower the pan with the tube.

Remove the oil pan bolts

To remove the oil pan bolts from a 2008 Chevy Cobalt, you'll first need to drain the engine oil. Next, remove the engine drive belt and the lower AC compressor bolt.

Now, you can remove the oil pan bolts. Make sure to get all of them out, as some can be hidden between the casting journals. There are a bunch of 13mm bolts, one 13mm nut, and four or six larger bolts that go sideways through the pan towards the driver's side of the engine.

After you've removed all the bolts, tap the pan with a hammer. If it doesn't start to drop, you've missed some bolts.

Remove the oil pan

To remove the oil pan from a 2008 Chevy Cobalt, follow these steps:

First, make sure you have the right tools and safety equipment. You'll need a jack, jack stands, wheel chocks, a new oil pan, new oil, and a new oil filter. It's also a good idea to have some rags or absorbent material on hand to clean up any spilled oil. Wear gloves and safety goggles to protect your hands and eyes.

Now, here are the steps to remove the oil pan:

• Park your car on a level surface, engage the parking brake, and place wheel chocks behind the driving wheels.
• Raise the front of the car using the jack and support it securely on jack stands.
• Locate the oil pan under the engine. It is usually located towards the bottom of the engine and is responsible for holding the engine oil.
• Place a drain pan or container under the oil pan to catch any spilled oil.
• Remove the engine drive belt. This will give you better access to the oil pan and its bolts.
• Locate and remove the lower AC compressor bolt. This will provide more clearance for removing the oil pan.
• Identify all the oil pan bolts. There should be several bolts securing the oil pan to the engine. Make sure you don't miss any bolts, as this can make it difficult to remove the oil pan.
• Using the appropriate size socket or wrench, loosen and remove the oil pan bolts. Some of the bolts may be difficult to access, so take your time and work carefully.
• Gently tap the oil pan with a rubber mallet or a piece of wood to loosen it from the engine block. Be careful not to use excessive force, as this may damage the oil pan or the engine.
• Carefully remove the oil pan from the vehicle. Pay attention to any attached components, such as the dipstick tube, and detach them as necessary.

At this point, the oil pan should be removed from the vehicle. Make sure to dispose of the old oil and oil pan responsibly and follow the manufacturer's instructions for installing a new oil pan and adding new oil.
