2007-2008 Chrysler Pacifica: A Very Brief Second Generation
Original Chrysler Pacifica
An odd mix of cost-cutting coupled with a more powerful 4.0-liter V-6 engine
and six-speed transmission
were the basics of the first and only Chrysler Pacifica crossover update. The new powertrain had better gas mileage and acceleration, and the crossover gained stability control and a price cut. (A 3.8 liter engine
was sold on base models.)
New Chrysler Pacifica standard safety features were all-row side curtain air bags and stability control (the latter included throttle-by-wire). An optional rear back up camera was added, as well. The new Pacifica gained a 5-star safety rating from the National Highway Traffic Safety Administration (NHTSA) for front- and side-impact, and four stars (the highest rating of vehicles tested in its class) for roll-over.
Other options included heated first- and second-row leather seats, dual-zone temperature controls, hands-free communication, and satellite radio.
At the time, the typical Pacifica consumer was a married woman between thirty-five and fifty years old, with a college degree, an average annual household income of $85,000, and children over the age of 10.
The Chrysler Pacifica had easy step-across entry and exit and chair-height seats. The 2007 models brought a two-tone instrument panel and two-tone door trim, revised gauge graphics, and five- or six-passenger seating.
The new 4.0-liter SOHC V-6 engine
had a long stroke for low-end torque; it was rated at 255 hp @ 6000 rpm and 265 lb. ft. of torque @ 4200 rpm, higher than the 3.5-liter V-6 engine use earlier.
Engineers worked on cutting vibration at the mounts, radiated noise, crank shaft torsionals, and induction snorkel noise, resulting in new main bearing diameters, lower-reciprocating-mass piston-and-rod assemblies, a better block and oil pan structure, reduced bearing clearance, and a low-rumble intake manifold. An equal-length dual exhaust, dropped in at the end of the 2006 model year, was essentially the same as the single exhaust from the rear wheels forward, though it did have twin mufflers.
Other changes included:
- Modified powertrain mount cradle assembly with new mounts
- Larger halfshafts
- New accessory drive package
- New electronically controlled clutch on all-wheel-drive models
- Modified engine cooling system
- New front bearings
- New power transfer unit mounting structure and input shaft
The new six-speed automatic transmission
was standard on all Pacificas with 4.0-liter V-6 engines.
Steve-577 asked BorgWarner if the new all wheel drive system sends torque to the rear wheels at a standing start before
there is wheel spin at the front wheels, or after. It turns out that yes, it does send torque sent to the rear wheels
before the front wheels spin, under hard throttle. At highway speeds, the system disengages.
A Borg-Warner rep wrote: "The AWD system on the 2007 Pacifica all wheel drive uses information
from the steering wheel, throttle, and wheel speeds, to determine the
optimal system response to match driver desired vehicle behavior. It
will update this system response many times per second. At low speed, sudden changes in amount of throttle applied can facilitate
prompt system activation - in amounts determined by all of the underlying
parameters. The amount of torque transferred is continuously variable,
is of no set value and, if needed, can go to the maximum allowable torque
specified by Chrysler."
Meeting the new Pacifica
We met the Pacifica at a press event. Outside, the Pacifica resembled the new Aspen and Sebring, with their ribbed hoods (those are speed grooves, in case you were wondering; six concave, one convex), rounded-trapezoid grille, chrome, and front-end lines. Inside, they could hardly be more different, with interiors that appeared to have been designed by three different companies with different cultures.
The Pacifica looks much as it did inside, with a large black driver pod and a two-tone passenger pod; there was light woodgrain on the wheel, with strips on the dash and door. Care was taken to provide an unobstructed 180° view from the driver, for a light, spacious feel. The Pacifica started at $25,000 and go on up to about $36,000, well priced in the field.
valiant67 noted that those with the Mopar Keyless Entry Module (part number 04883257, known as EVS II) can change their own alarm settings (proceed at your own risk):
1) Unplug the harnesses from the EVS module.
2) Remove the 4 phillips screws from the bottom of the housing.
3) Carefully separate the halves of the housing so as not to disturb the circuit boards.
You should see 4 switches, Sw1 - Sw 4.
Chirping on - Sw 1 On
Chirping off - Sw 1 Off
Full automatic arming - Sw 2 On, Sw 3 On
Auto starter lockout only - Sw 32 Off, Sw 3 Off
manual arming only - Sw 2 On, Sw 3 Off
Instant trigger - Sw 4 On
Delayed (15 sec) trigger - Sw 4 Off
4) Once configured, reassemble the module and plug the harnesses in.

Optionals included leather, power ten-way driver seat, back-up sensors, video player, and heated front seats.
The AWD model added the 4.0 engine and six-speed transmission, bumped the alternator to 160 amps, and used 17-inch aluminum wheels.
The Touring model took the FWD specs and added six-passenger seating, sun visors with illuminated vanity mirrors, dual-zone automatic temperature control with a filter, trip computer, interior light package, leather-wrapped steering wheel, garage door opener, power ten-way driver seat, and body color door handles. Additional options, including HID headlights, power adjustable pedals a better stereo, backup camera, navigation, and heated second row seats, were available, and wheels went up to 19 inches.
