Changing the oil on a classic car like a 1970 Plymouth Hemi 'Cuda is an essential maintenance task that ensures your muscle car runs smoothly and stays in top condition. If you notice that your oil looks dark and grimy, or if it's been a while since your last oil change, it's time to refresh the engine oil. Proper oil changes help maintain engine lubrication, remove contaminants, and prevent wear and tear. To keep your Hemi 'Cuda running its best, here’s how you can change the oil:

Step 1: Gather Necessary Tools and Supplies

Before starting the oil change, make sure you have the following items:

Step 2: Prepare Your Vehicle

  1. Begin by parking your 1970 Plymouth Hemi 'Cuda on a flat, stable surface. To make accessing the oil drain plug easier, you may need to use a jack and jack stands or ramps to raise the front of the car. Ensure the vehicle is securely supported before crawling underneath.
  2. Put on gloves to keep your hands clean and protect them from hot oil.

Step 3: Locate the Oil Drain Plug

  1. Slide under the car and locate the oil drain plug on the oil pan. The oil pan is usually at the bottom of the engine, towards the middle/front of the vehicle. The oil drain plug looks like a large bolt and is usually at the lowest point of the oil pan.

Step 4: Drain the Old Oil

  1. Place the oil drain pan directly under the oil drain plug to catch the old oil.
  2. Use a socket wrench to loosen and remove the drain plug. Be careful as the oil may be hot if the engine was recently running.
  3. Allow all the oil to drain out completely. This might take a few minutes.

Step 5: Replace the Oil Filter

  1. While the oil is draining, look for the oil filter. It’s typically located on the side of the engine block. The oil filter is a cylindrical component, often white or black.
  2. Use an oil filter wrench to carefully unscrew and remove the old oil filter. Have the drain pan ready to catch any leftover oil from the filter.
  3. Take your new oil filter, apply a little bit of fresh oil to the rubber gasket (on the top of the filter). This creates a secure seal.
  4. Screw the new oil filter onto the engine by hand until snug. Then tighten it an additional quarter turn.

Step 6: Reinstall the Oil Drain Plug

  1. Once the oil has completely drained, wipe the area around the oil drain plug hole with a clean rag to remove any residual old oil.
  2. Reinstall the oil drain plug and tighten it securely with the socket wrench.

Step 7: Add New Oil

  1. Open the hood of your Hemi 'Cuda and locate the oil filler cap. It’s usually on the top center of the engine, marked with an oil can symbol.
  2. Remove the oil filler cap and insert a funnel into the opening to avoid spills.
  3. Pour the correct amount and grade of new motor oil into the engine. Refer to your vehicle’s manual for specifics.
  4. After adding the oil, replace the oil filler cap securely.

Step 8: Check the Oil Level

  1. Start the engine and let it run for a minute to circulate the new oil.
  2. Turn off the engine and wait a few minutes for the oil to settle.
  3. Pull out the oil dipstick, wipe it clean, reinsert it fully, and then pull it out again to check the oil level. The oil should be between the "min" and "max" marks on the dipstick. Add more oil if necessary.

Step 9: Dispose of Old Oil Properly

  1. Transfer the old oil from the drain pan into a suitable container with a lid.
  2. Take the used oil and old filter to a recycling center or auto parts store that accepts used oil for proper disposal.

By following these steps, you ensure your 1970 Plymouth Hemi 'Cuda remains in top running condition, preserving the performance and longevity of the powerful engine.
