2015-2022 2nd Gen 2018 Chevy Colorado GMC Canyon Oil & Oil Filter Change 3.6L V6

Introduction

This tutorial will guide you through the process of changing the oil and oil filter on a 2018 Chevy Colorado with a 3.6L V6 engine. The steps outlined are applicable to most second-generation Colorados and GMC Canyons. Always refer to your vehicle's manual for specific instructions and recommendations.

Step 1: Prepare for the Oil Change

• Gather Tools and Materials:

  • Ratchet with an extension
  • 24mm socket for the oil filter
  • 15mm socket for the oil drain plug
  • New oil filter and gasket
  • New engine oil (5W-30 full synthetic, at least 6 quarts)
  • Oil catch pan
  • Cardboard (to protect the ground)

• Loosen the Oil Cap:

  • Remove the oil cap from the engine to allow air to flow in, which helps the oil drain more smoothly.

Step 2: Remove the Old Oil Filter

• Locate the Oil Filter:

  • The oil filter is a cartridge style located on the engine. Use the 24mm socket to loosen it.

• Unscrew the Oil Filter:

  • Once loosened, the oil will begin to drip into the catch pan. Remove the filter completely and dispose of it properly.

• Clean Up:

  • Wipe any residual oil from the area around the oil filter to prevent contamination.

Step 3: Drain the Old Oil

• Locate the Oil Drain Plug:

  • The oil drain plug is typically underneath the oil pan.

• Unscrew the Drain Plug:

  • Place the oil catch pan underneath and use the 15mm socket to loosen and remove the drain plug. Be cautious as the oil may be hot. Allow the old oil to fully drain.

• Replace the Drain Plug:

  • After the oil has drained, reinsert the drain plug and hand-tighten it.

Step 4: Install the New Oil Filter

• Prepare the New Filter:

  • Before installing the new filter, apply a small amount of new engine oil to the rubber gasket on the new filter. This helps it seal properly.

• Install the New Filter:

  • Screw in the new oil filter by hand until snug. Do not overtighten; follow the manufacturer's recommendations.

Step 5: Fill with New Oil

• Add New Oil:

  • Pour approximately six quarts of 5W-30 full synthetic oil into the engine through the oil filler cap. Ensure the oil is Dexos-rated.

• Check Oil Level:

  • After filling, use the dipstick to check the oil level. Ensure it’s at the recommended level and avoid overfilling.

Conclusion

You have successfully changed the oil and oil filter on your 2018 Chevy Colorado. Remember to dispose of the old oil and filter properly. It's good practice to check your oil level regularly and perform this maintenance every 5,000 to 7,500 miles, depending on your driving conditions. If you have any further questions or need assistance, refer to your vehicle’s manual or consult a professional.
