Engine Oil and Filter Requirements
The heart of the 2008 Pacifica is the 3.8-liter V6 engine, a durable powerplant that benefits significantly from the viscosity and additive package of synthetic motor oil. For this vehicle, the recommended viscosity is 5W-20. The oil capacity, including the filter change, is 5.0 quarts. It is critical to verify the oil level after refilling the crankcase to ensure proper lubrication coverage.
When changing your oil, the drain plug should be torqued to 20 ft/lbs to prevent leaks or damaged threads. AMSOIL offers four distinct motor oil options to suit different driving needs and vehicle mileages. The Signature Series 5W-20 is the top-tier choice, engineered to resist horsepower loss and wear for up to 25,000 miles. For drivers who prefer a slightly shorter service interval but still demand synthetic performance, the Extended-Life 5W-20 provides 20,000 miles of protection with enhanced cleaning power to keep the engine running smoothly.
For owners looking for a cost-effective solution that still exceeds conventional oil standards, the OE 5W-20 is an excellent choice. It features a 100% synthetic formulation that effectively fights sludge and deposits. If your Pacifica has accumulated significant mileage, specifically over 75,000 miles, the AMSOIL 5W-20 High-Mileage Motor Oil is designed with boosted detergents and dispersants to clean internal contaminants and seal protection to reduce leaks. This product guarantees 12,000 miles of protection and helps restore engine performance.
In conjunction with the oil, a high-quality filter is non-negotiable. The AMSOIL Oil Filter provides 99 percent filtering efficiency at 20 microns, allowing lower restriction for better lubrication. It holds a greater capacity for small, wear-causing contaminants than competing filters. Alternatively, the WIX Oil Filter is a premium option that offers media improvements over original equipment manufacturer-branded filters. Both filters ensure your engine stays clean and protected during the service interval.
Transmission and Differential Fluids
Proper lubrication extends far beyond the engine bay. The automatic transmission in your Pacifica plays a vital role in how the vehicle drives, handles loads, and maintains efficiency. The transmission specifications vary depending on whether your model is equipped with the 41TE (4-speed) or 62TE (6-speed) automatic transmission.
For the 4-speed 41TE transmission, the total fill capacity is 9.7 quarts, while the initial fill requires 4 quarts. The 6-speed 62TE transmission has a total fill capacity of 9 quarts and requires 5.5 quarts for an initial fill. In these applications, AMSOIL recommends using either the Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid or the OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid. Both fluids are designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. They remain fluid in sub-zero temperatures and provide reserve protection during heavy use. The OE Multi-Vehicle fluid is particularly noted for promoting smooth, shudder-free shifts and guarding against leaks.
To maximize transmission life, changing the transmission filter is highly recommended. The WIX Transmission Filter features premium media that offers improvements over OEM-branded filters, helping to maintain the fluid’s cleanliness and protect internal components from wear.
The rear differential and transfer case also require specific attention. The Pacifica, when equipped with All-Wheel Drive (AWD), has a rear differential requiring 1.5 pints of lubricant. AMSOIL’s SEVERE GEAR® line is ideal for this application. The 75W-90 100% Synthetic Gear Lube contains friction modifiers for limited-slip applications and helps reduce operating temperatures. For heavier loads or extreme conditions, the 75W-110 and 80W-90 variants offer advanced protection against wear and rust, extending the life of the gears and seals.
Coolant and Brake Fluid
Maintaining the cooling system is crucial for the longevity of the V6 engine. The 2008 Chrysler Pacifica has a cooling system capacity of 11.8 quarts. You can choose between two types of coolant depending on your preference for pre-mix or concentrated fluid. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol 50/50 pre-mix formulation that protects all cooling system metals, gaskets, and hoses. It is phosphate, nitrate, nitrite, silicate, borate, and amine-free, ensuring compatibility with various cooling system components.
Alternatively, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated fluid that requires mixing with distilled or high-quality water. This option is non-toxic and offers exceptional protection, safeguarding against metallic corrosion and erosion for up to 150,000 miles or 5 years.
For the braking system, the Pacifica requires a hydraulic brake fluid meeting MS-4574 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is the recommended choice. This fluid provides excellent responsiveness for ABS and traction control systems and maintains a stable viscosity across a wide temperature range, ensuring consistent braking performance regardless of weather conditions.
Vehicle Background
The 2008 Chrysler Pacifica represents a significant chapter in the brand’s history, serving as one of the first minivans to successfully blend the utility of a traditional wagon with a more car-like driving dynamic. Built on the widely respected “S platform,” which it shares with the Chrysler Sebring and Dodge Magnum, the Pacifica offered a sophisticated engineering foundation that appealed to families looking for versatility without sacrificing style. The 3.8-liter V6 engine, often identified by its engine code L, was a staple of Chrysler’s lineup during this era, known for its smooth power delivery and reliability. It typically produced around 250 horsepower, providing ample power for a vehicle of its size, whether it was hauling passengers, cargo, or towing small trailers. The interior was designed with a focus on practicality, offering sliding doors and configurable seating that made it a favorite among parents and daily commuters alike. This model year continues to be a popular choice for those seeking a spacious, comfortable, and durable family vehicle.
Additional Maintenance and Care
Beyond the essential engine and transmission fluids, several other products can help maintain the overall health and appearance of your 2008 Pacifica. For seasonal storage or to ensure fuel stability, the AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, protecting against varnish and gum buildup. If you store the vehicle for extended periods, the AMSOIL Engine Fogging Oil can be used to protect internal engine components from corrosion.
To improve fuel economy and restore lost power, the AMSOIL P.i. Performance Improver Gasoline Additive is an effective solution. It restores up to 14% horsepower and clears fuel injectors, which is particularly beneficial for engines with higher mileage. For general cleaning and protection, the AMSOIL Synthetic Multi-Purpose Grease offers excellent low-temperature pumpability, while the Heavy-Duty Metal Protector provides a long-lasting wax-like coating to resist rust and corrosion from salt and moisture.
Finally, for vehicle care, the AMSOIL Miracle Wash Waterless Wash and Wax Spray provides a fantastic shine and protective finish without the need for water, while the Brake and Parts Cleaner quickly removes oil, grease, and brake dust to keep components looking new and performing safely.
