Step-by-Step Guide:
1. Park the Truck Safely: Park your 1989 Chevy 4.3L truck on level ground, turn off the engine, and engage the parking brake.
2. Prepare Under the Truck: Place the oil drain pan beneath the oil drain plug, which is located on the bottom of the oil pan.
3. Locate the Oil Filter: The oil filter is typically located near the top of the engine, on the driver's side. It's a cylindrical-shaped component with "OIL FILTER" printed on it.
4. Loosen the Oil Filter: Using an oil filter wrench, turn the oil filter counterclockwise to loosen it. Be careful not to spill any oil.
5. Remove the Oil Filter: Once the oil filter is loosened, remove it by turning it counterclockwise until it comes off.
6. Apply a Thin Coat of New Oil to the Gasket: Before installing the new oil filter, apply a thin coat of new oil to the gasket of the filter. This helps create a better seal.
7. Install the New Oil Filter: Screw on the new oil filter by hand until it is snug. Avoid over-tightening the filter, as this can cause damage.
8. Replace the Oil Drain Plug: Once the new oil filter is installed, replace the oil drain plug. Tighten the plug until it is snug.
9. Add New Oil: Use a funnel to add new oil to the engine through the oil filler cap. Refer to your vehicle's owner's manual for the exact amount of oil required.
10. Check the Oil Level: Start the engine and let it run for a few minutes. Then, use the dipstick to check the oil level. Make sure the oil level is between the "full" and "add" marks on the dipstick.
11. Dispose of Old Oil and Filter: Properly dispose of the old oil and filter according to local environmental regulations.
Changing the oil and replacing the oil filter in your 1989 Chevy 4.3L truck is a simple maintenance task that can extend the life of your engine and keep it running smoothly.
