Which engine? 4 cylinder (2.4 lit) or V6 (2.7 lit)? Two different procedures as well as different belts. The 4 cylinder also has a balance belt. See next image:
Here's the 2.7 V6 belt:
The replacement procedure is nearly the same at the start (removing, accy drive belts, pullys, support engine & remove front engine mount, remove T.B covers, disconnect Cam Position Sensor & Crank Position Sensor connectors, etc.). When you get to this point on the V6, you also have to remove the front engine mounting bracket from the front of the engine (4 14mm bolts, also a 12mm bolt which bolts the dipstick tube to the side of it) Put crank shaft at TDC (top dead center w/ALL timing marks aligned) remove hydraulic tensioner (2 12 mm bolts), then remove the belt. You'll need to recompress the hydraulic (auto) tensioner in a vise and insert a retaining pin through the pin-holes at the top (through the tensioner piston) to keep it compressed when you reinstall it. Otherwise, you won't be able to install it. Assembly is reverse order of dissassembly. Inspect your pullys while you're in there (check for pully bearing noise, leaking grease, smooth rotation, also the water pump pully, etc.) Replace components as needed. Careful not to damage Crankshaft Position Sensor wire harness.
The 4 Cylinder is quite different. You not only change the timing belt, but also the countershaft (balance) belt, which is behind the crank position sensor blade. IMPORTANT: ALL TIMING MARKS ALIGNED BEFORE REMOVING ANYTHING) There are two (2) counter-shafts (balance shafts). one driven by the timing belt, the other by the crankshaft sprocket behind the timing belt sprocket at the front of the crankshaft.
