236 Vehicle Care
1. Engine Oil Drain Plugs
2. Seals
Steps to follow:1. Remove the two engine oil drain plugs from the bottom of
the engine oil pan. One drain
plug drains the external oil tank
via the oil transfer supply line.
The other drain plug drains
residual oil from the crankcase
sump. Allow the oil to drain.
2. Once the oil has been drained from the engine, remove the
engine oil filter and allow the oil
to drain. 3. Reinstall both drain plugs and
tighten them to 25 Y
(18 lb ft).
4. Replace the oil filter and tighten it three-quarters to one
turn after gasket contact. See
Maintenance Replacement
Parts 0323 for the correct filter.
5. Oil is filled through the opening in the top of the external
engine oil tank. Remove the oil
fill cap.
6. Add oil to the oil tank. See Capacities and Specifications
0326.
7. Install the oil fill cap and insert the dipstick, if removed.
8. Start the engine and let it run at idle for at least 15 seconds.
This will circulate the fresh
engine oil through the
lubrication system.
9. Shut off the engine and check the oil level as described under
“Checking Engine Oil (ZR1,
Z06, Grand Sport, and Stingray
with Z51).”
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See Recommended Fluids and
Lubricants 0321.
Specification
Use engine oils that meet the
dexos2 specification.
Engine oils that have been
approved by GM as meeting the
dexos2 specification are marked
with the dexos2 approved logo. See
www.gmdexos.com.
