Absolutely nothing like a Subaru.
Basically...
Lift right (passenger side) front and remove tire.
Remove plastic shroud covering engine pulley
put second jack under engine and lightly lift the engine
move some AC and power steering hoses after unbolting clamps
remove the motor mount (thats what the second jack is for)
remove accessory belts
remove water pump pulley (tight fit 4 bolts)
remove timing cover top.
remove crank pulley nut.. Trick to get it off use a breaker bar and bump starter
remove crank pulley
remove lower TB cover
you now have access to TB
align crank pulley to timing marks
check cam pulley to be on its timing marks
I marked crank and cam pulleys and old belt with paint lines and then
transfered the marks to the new belt (dif colors top and bottom)
Remove tensioner pulley and timing belt belt
(count the teeth between marks on old and new belts when transferring marks.)
install new belt and re-assemble.
This is overly simplified but the idea is there...
If you want more explicit info ask...
You will need metric sockets and wrenches 8mm~19mm 3/8", a 22mm socket 1/2" drive, a 1/2" breaker bar, a 1/2" torque wrench, 3/8" ratchet, spark plug socket 3/8" (optional) , 3/8" extensions.
1 timing belt
1 AC belt (optional but it was cracked on my wife's Spec)
1 good frame of mind

possibly 4 new NGK Platinum Spark plugs and (optional socket)
Pretty much a simple job...I would not want to tackle a 2.4L on an Optima but the Spec is EASY.
Like I said there is more complete info available if you ask and I/WE are here to help..
