How do you set the timing on a 1986 Chevy Caprice 262 43L V6?

Go to your library and see if they have a Chiltons manual otherwise go to a bookstore and buy one, they are cheap. I have never worked on one of the V-6 engines but setting the timing usually involves rotating the distributor and using a timing light. I am not sure if this is the case on computer controlled engines since I have never had to set the timing on any newer car I have worked on. If it is bad and you have a lot of miles, you may have a timing belt going bad. They get loose when they get old and often jump a notch. VBD

Where is the engine timing mark on an '86 Chevy Astro 43L?

I have a '90 so I think it would be the same, on mine it is at the front of the engine on the bottom pulley. (crankshaft pulley or vibration dampener) To view the scale and mark I have to look down, a little on the drivers side of center. Beside the break resivour is a good viewpoint, looking just over the timing light. I have to run the timing pickup coil in through the drivers door or window and into the open doghouse cover. Good luck. God Bless!

0 degrees,should say right on the fan shroud on the same sticker that tells the spark plug gap. In order to time it correctly you must unhook the esc electronic spark control wire which is a tan wire with a black stripe located under the black cover on the passenger side firewall. It may set off a service engine soon light. When your done timing it unhook the battery cable and the light should go out.
