There is a big difference between replacing a car engine vs replacing a car battery. The hardest part is lifting the heavy battery out and putting the new one in. With a gas engine, there is belts, timing, oil, and lots of other things I am not even aware of.

Almost all of those things -- all you mention, and most of the "lots of other things" -- are within (or firmly attached on the outside of) the engine itself, and are swapped out as integral parts with the engine.
