I want to change the oil in my 2000 Chevy Silverado pickup, but the
owner's manual conveniently fails to show where the oil drain plug is
under the truck. I found the oil filter, but before I start unplugging
things I want to make sure I have the right plug. I need a picture, I
guess, with an arrow pointing to the correct plug. can you help?

Hi Deputy Dawg, 

I found a nice picture of the 2002 vortec 4300 which should be very
similar to your engine in your Silverado. I believe the 4800 was the
standard for 2000.

I found this image of a 4800

and this one of the 4300

I added the arrow to the second one showing a drain plug on the side
of the oil pan under the oil filter. I am thinking based on the image
of the 4800 that your drain plug will be on the other side. Same basic
location, just on the right side of the car instead of the left.

If your Silverado has a skid plate, there will be holes on either side
of the oil pan to allow access to the drain plug. If you need any
further clarification on this question please request clarification
prior to rating this answer.

Thanks,
