How do i change oil in 1978 Corvette?

Answer 1

1. Locate oil drain plug (on the driver's side of the drain pan near the oil filter - behind the front wheel).

2. Place container underneath plug location.

3. Remove plug with socket or wrench (caution - oil may be hot!)

4. Let oil drain out (removing oil fill cap may speed drain & help prevent "gulping")

5. (Optional but recommended) Remove oil filter - you may need to use a special wrench. Also, be careful since filter will be full of (potentially) hot oil.

6. Install new oil filter after lubricating the rubber gasket with oil.

7. Replace drain plug & torque to 20 ft-lbs. It's also a good idea to verify the oil pan bolts are tight at the same time.

8. Add four quarts of clean oil via oil fill cap, let settle, & check level on dipstick. If the level is above the ADD mark, run engine for about a minute & check for leaks underneath the car.

9. After oil has circulated, re-check dipstick & add oil as necessary.

10. Don't forget to replace the oil fill cap!

Also, it is not really necessary to raise the front of the car. As low as it is, there's still enough clearance for my oil drain container, and the oil drain plug is within easy reach from the side of the car.

Make sure you dispose of the dirty oil properly. Most auto parts stores (Advance, AutoZone, etc.) will reclaim used oil for free, so there's no reason to dump it down a storm drain & contaminate the environment.
