Changing Oil Pan: 1998 Dodge Ram 1500 Diy Guide

Changing the oil pan on a 1998 Dodge Ram 1500 can be a challenging task, as some components may need to be removed or adjusted to access and replace the oil pan. It is recommended to disconnect the negative cable from the battery and remove the engine oil dipstick. One may also need to remove the bending brace to the transaxle attaching bolt and the dust cover to the transaxle housing. Additionally, it may be necessary to loosen the engine mounts and raise the engine slightly to create enough space to slide out the old oil pan and install the new one. It is important to use a new pan gasket and properly torque the screws to ensure a secure fit.

Removing the oil pan

To remove the oil pan from a 1998 Dodge Ram 1500, follow these steps:

Firstly, disconnect the negative cable from the battery and remove the engine oil dipstick. This will ensure that no power is supplied to the engine during the removal process and that the oil level is correctly adjusted after the new oil pan is installed. Next, drain the engine oil to prevent spillage when removing the oil pan.

Now, you need to create some space to access the oil pan. Start by removing the bending brace to the transaxle attaching bolt. Then, remove the bolts attaching the dust cover to the transaxle housing and lower the dust cover. This will give you the necessary access to the oil pan bolts.

With the dust cover out of the way, you can now remove the oil pan screws and carefully take out the oil pan. Be cautious not to damage the surrounding components and catch any spilled oil with a suitable container.

It is important to clean the surfaces and apply a bead of high-quality silicone rubber adhesive sealant or an equivalent product to ensure a secure seal. Install a new pan gasket and position the new oil pan, tightening the screws to the specified torque (12 Nm or 105 in. lbs.).

Finally, reinstall the dust shield and bending brace to the transaxle housing. Lower the vehicle and reinsert the oil dipstick. Reconnect the negative cable to the battery, and fill the crankcase with oil to the appropriate level.

Some people suggest that it is not necessary to hoist the engine unless you have a deep transmission pan or a longer-stroked crankshaft. However, others recommend removing the starter and transmission brackets to gain better access to the oil pan. Additionally, removing the exhaust pipe and left engine-to-transmission mount may provide more clearance.

Disconnecting the battery

To disconnect the battery of your 1998 Dodge Ram 1500, follow these steps:

First, locate the battery under the hood of your vehicle. The battery is typically located near the engine. Once you have located the battery, identify the negative cable, which is usually black and marked with a "-" symbol. It is important to always disconnect the negative cable first to avoid any potential electrical shorts. Use an appropriate-sized wrench or socket to loosen the nut that secures the negative cable to the battery terminal. Do not allow the wrench or socket to come into contact with any metal parts of the vehicle, as this could cause a short circuit. Slowly and carefully remove the cable from the battery terminal. Ensure that the cable does not touch any metal surfaces or components. Place the cable aside, ensuring that it cannot accidentally come into contact with the battery terminal.

Now that the negative cable is disconnected, you can proceed with the rest of the oil pan repair or replacement. It is recommended to refer to a repair manual or seek guidance from a qualified mechanic to ensure that you perform the oil pan-related tasks correctly and safely. Once you have completed the necessary repairs or replacements, you can reconnect the battery. To do so, carefully attach the negative cable back to the negative terminal, ensuring a secure connection. Tighten the nut with your wrench or socket. Re-check that the cable is securely attached and that there are no signs of damage or corrosion on the cable or terminal. Finally, close the hood of your vehicle and start the engine to ensure that the electrical system is functioning properly.

It is important to note that working with automotive batteries can be dangerous if not done properly. Always exercise caution and wear appropriate safety gear, such as gloves and eye protection. If you are unsure about any aspect of the process, it is best to consult a professional mechanic or seek advice from a trusted source.

Draining the oil

To drain the oil from your 1998 Dodge Ram 1500, first disconnect the negative cable from the battery. Then, remove the engine oil dipstick. Next, you'll need to remove the left engine-to-transmission strut. Loosen the right-side engine support bracket cushion thru-bolt nut and raise the engine slightly. Be careful not to raise it too much—just enough to slide the oil pan back out. Now, you can remove the oil pan screws and take out the oil pan.

Before you begin this process, it's important to make sure you have the right tools and safety equipment. You'll also need to consult a repair manual or a trusted online forum for your specific model of Dodge Ram to ensure you're following the correct procedure.

Removing the dust cover

To remove the dust cover as part of the process of changing the oil pan on a 1998 Dodge Ram 1500, follow these steps:

First, disconnect the negative cable from the battery and remove the engine oil dipstick. Then, remove the bending brace to the transaxle attaching bolt. Next, remove the bolts attaching the dust cover to the transaxle housing. Lower the dust cover to gain access to the oil pan bolts.

At this point, you can remove the oil pan screws and take out the oil pan.

It is important to note that you do not need to hoist the engine unless you have a deep transmission pan. However, you will need to remove the starter and transmission brackets to drop the pan.

When you are ready to install the new pan, clean the surfaces and apply a 1/8-inch bead of Mopar(R) Silicone Rubber Adhesive Sealant or equivalent at the parting line of the chain case cover and the rear seal retainer. Use a new pan gasket and install the pan, tightening the screws to 12 Nm (105 in. lbs.). Finally, reinstall the dust cover and bending brace to the transaxle housing.

Removing the bolts

To remove the bolts from the oil pan of your 1998 Dodge Ram 1500, you will first need to drain the oil. You will also need to disconnect the battery and remove the starter and the transmission brackets. It is also recommended to remove the dust cover on the transmission, as it is linked to the oil pan and will get in the way.

Once you have accessed the oil pan, you will need to remove the bolts holding it in place. There are 14 bolts on the oil pan of a 1998 Dodge Ram 1500. Before attempting to remove the bolts, apply a penetrating oil such as PB Blaster to the threads of the bolts to help loosen them. If the bolts are very rusty, you may need to apply heat to them using a propane torch.

When removing the bolts, be sure to use the correct tools and turn them counter-clockwise to loosen. Do not over-tighten the bolts or use the wrong tools, as this can strip the threads and make them difficult to remove. If the bolts are stripped, you may need to use a bolt extractor socket or drill them out. Start with a small drill bit and work your way up to a larger size if needed.

If there is a brace in the way of the oil pan rear bolts, you will need to remove it. This brace comes from the DS engine mount and down to the transfer case and transmission. You can cut this brace with a reciprocating saw and weld it back together once you're finished.
