you can even do it from the top. 32mm socket and a breaker bar. 10mm socket to remove valve cover.
remove valve cover. remove tensioner. compress new tensioner. install new tensioner (55 ft-lb). put a screwdriver down against the chain guide and strike sharply to release the new tensioner. install valve cover.
my haynes manual has a pretty good description of the steps needed.

Q: What's the difference between a bolt and a screw?
A: First, you screw. Then, you bolt.
i have the haynes manual but its for a cobalt should be the same thing right? so im kind of confused..... so u said the hex bolt sticks out what does that have to do with it if you have to remove your valve cover?
the hex bolt is the tensioner. the tensioner screws into the side of the block or head. you cannot remove the tensioner out from under the valve cover.
removing the valve cover allows you to properly release the compressed tensioner. you must install the tensioner in the compressed position or you will damage the chain or guide. if you do not release the tensioner from its compressed position, oil pressure will eventually release it, but until you build up oil pressure, you have slack in the chain. some of the shortbussers have gotten away with it, but i wouldn't chance it on my own car.

the whole process took me less than an hour.
How much is involved in removing the valve cover. I don't have the money for a haynes manual at this point in time, but the mechanic is telling me i will likely need a new motor, who knows, and i sure as hell can't afford that.
well...without having a look at it, i can't tell you if you need a new motor or not, but i'd first start with a $60 part that is a known issue, rather than tossing a whole motor at it.
