Engine Oil - GMC 2001 Sonoma Owner's Manual

Before closing the hood, be sure all the filler caps are on
properly. Then lift the hood to relieve pressure on the
hood prop.
Remove the hood prop from the slot in the hood and
return the prop to its retainer.
Then pull the hood down firmly to close. It will latch
when dropped from 10 to 12 inches (25 to 30 cm)
without pressing on the hood.

Checking Engine Oil
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
See "Engine Compartment Overview" in the Index for
more information on location.
The engine oil dipstick on
the "VORTEC" 2200 L4

dipstick handle on the
