You might need to remove the 2.2-liter engine from the 1995 Chevrolet S-10 to rebuild it or you may want to remove it to upgrade to a V-8. When removing the engine, if you are going to reinstall it, you should keep the bolts separated so you don't have to look for them when you do the re-installation. The Chevrolet 2.2-liter engine is a workhorse and if well-taken care of, could amass tons of miles before it needs to be rebuilt or replaced. If you use the truck as a work truck and the body is still in good condition, remove the 2.2-liter engine in favor of a V-8 which is an easy conversion.
