How to Change the Oil on a 95 Astro Van
Always change your oil filter and oil at the same time. (tools image by CraterValley Photo from

The 1995 Chevrolet Astro van uses a Vortec 4.3 litre motor. This is a six-cylinder motor that is ideal for minivans. The fuel economy is better, but it still has plenty of power when needed. Changing the oil every 3,000 miles or every 3 months is recommended for ensuring you get the most out of this motor. Failure to change oil on a regular basis will cause the oil to break down and the motor will have no lubrication. This will cause the motor to eventually seize up.

Skill level:

Things you need

  • Crescent wrench
  • Drain pan
  • Oil filter wrench

  1. 1

    Crawl under the van and locate the engine drain plug. It will be located at the very bottom of the motor.

  2. 2

    Place a drain pan underneath the drain plug. Unscrew the drain plug with a crescent wrench. Allow all the oil to drain out in to the drain pan. Tighten the plug once the oil has drained out.

  3. 3

    Unscrew the oil filter with an oil filter wrench. The oil filter is located by the motor.

  4. 4

    Spread engine oil around the gasket of the new oil filter. Pour in half a quart of oil in to the oil filter. Screw the oil filter to the oil filter housing with your fingers. Do not wrench tighten the oil filter as this could damage the threads of the oil filter.

  5. 5

    Open the bonnet to access the engine compartment. Locate the oil filler cap on the valve cover. Fill with four quarts of oil.

  6. 6

    Check the oil level by pulling the engine oil dipstick next to the motor. Wipe the engine oil dipstick with a fresh towel. Insert the dipstick back in to the tube and pull it out. The fluid level will be indicated on the dipstick.

  7. 7

    Pour in additional oil if needed. Start the van and let it run for five minutes. Turn the van off and allow it to sit for five minutes. Check the oil once again. Fill if needed.

Tips and warnings

  • Use caution when working under the van. Ensure the parking brake is set and the van is on a flat even surface.
