BMW 635d Oil Change Procedure - A Step-by-Step Guide

Regular oil changes are crucial for maintaining the performance and longevity of your BMW 635d. Changing the oil at recommended intervals helps keep the engine running smoothly, improves fuel efficiency, and prevents potential damage. If you're ready to tackle this task yourself, follow our step-by-step guide below to ensure a successful oil change.

What You'll Need:

• Oil filter (compatible with BMW 635d model)
• Engine oil (check your vehicle's specifications for the recommended oil type and quantity)
• Wrench
• Oil drain pan
• Oil filter wrench
• Rubber gloves
• Rag or paper towels

Step 1: Prepare Your Vehicle

Park your BMW 635d on a flat surface and turn off the engine. Ensure that the vehicle is cool to prevent any burns during the procedure.

Step 2: Locate the Oil Drain Plug

Position yourself under the vehicle, typically on the passenger side. Locate the oil drain plug, which is usually a large bolt or plug at the bottom of the oil pan.

Step 3: Place the Oil Drain Pan

Position the oil drain pan directly below the oil drain plug to catch the old oil as it drains out. Make sure it is properly aligned to avoid spills.

Step 4: Unscrew the Drain Plug

Using an appropriate wrench, carefully loosen the drain plug by turning it counterclockwise. Be cautious as the oil may come out quickly. Once loose, you can remove the plug entirely and allow the oil to drain fully into the pan.

Step 5: Remove the Old Oil Filter

Locate the oil filter, typically positioned near the oil pan. Using an oil filter wrench, carefully unscrew and remove the old filter. Ensure that the old filter gasket comes off with the filter. Wipe away any excess oil around the filter housing.

Step 6: Install the New Oil Filter

Dip your finger into some fresh oil and apply a thin layer to the rubber gasket on the new oil filter. This helps create a proper seal. Carefully screw in the new oil filter by hand until it is hand-tight. Use the oil filter wrench to give it an additional quarter turn to secure it.

Step 7: Replace the Drain Plug

Once the oil has completely drained from the oil pan, clean the drain plug with a rag or paper towel. Apply a small amount of fresh oil to the drain plug threads and then reinstall it. Tighten the drain plug clockwise using your wrench, ensuring it is securely in place but avoid overtightening.

Step 8: Add Fresh Oil

Refer to your vehicle's manual to determine the correct oil type and quantity needed for your BMW 635d. Locate the oil fill cap, usually found on the top of the engine. Unscrew the cap and carefully pour in the recommended amount of fresh oil. It's advisable to add oil gradually and check the oil level using the dipstick until you reach the proper amount.

Step 9: Check for Leaks

With the new oil and filter in place, start your engine and let it run for a few minutes. Then, inspect the area around the oil drain plug and oil filter for any signs of leaks. If you notice any leaks, immediately turn off your engine and address the issue.

Congratulations! You have successfully completed an oil change for your BMW 635d. Dispose of the old oil responsibly at a local recycling center or an auto parts store that accepts used oil. Remember to always consult your vehicle's manual for specific instructions and recommended maintenance intervals.
