What should the timing be set at after you have replaced chain on a 1994 Chevy s10 2.2 liter engine?

You can't just set the timing to a specific degree on a 1994 Chevy S10 2.2L engine after a timing chain replacement. These engines use a non-adjustable timing chain. The timing is fixed by the chain's design and the sprockets.

The crucial step is to ensure the chain is installed correctly according to the factory service manual. This includes:

* Correctly aligning the crankshaft and camshaft sprockets to their corresponding marks (usually dots or notches). This is absolutely critical and must be done precisely. Incorrect alignment will cause severe engine damage.

* Proper chain tension. Many newer engines have automatic tensioners, but you need to check the manual to see if there are any specific adjustments needed.

After installing the chain correctly, you do not adjust the timing. The only timing adjustment possible on this engine would be done by a mechanic using a specialized tool to adjust the computer's control over the ignition timing, but this isn't related to the timing chain itself.

Using a service manual is absolutely essential. It will have detailed instructions, diagrams, and specifications for the proper chain installation procedure for your specific engine. Attempting this repair without one is highly discouraged. Incorrect installation can lead to catastrophic engine failure.
