The engine oil fill cap
for the VORTEC 4800,
5300, 6000 and 8100 V8
engines is located on the
engine valve cover, on
the passenger’s side of
the vehicle.
Your vehicle may have a cap with text and a graphic,
or just a graphic as shown. See “Engine Compartment
Overview” in the Index for more information
on location.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you’re through.
