2008 Jeep Grand Cherokee Overland Diesel For Sale: A Comprehensive Buyer’s Guide
The Allure of the 2008 Grand Cherokee Overland Diesel
The WK generation of the Jeep Grand Cherokee (2005-2010) was a significant leap forward in terms of refinement and technology for Jeep. Within this generation, the 2008 Overland trim represents the pinnacle of luxury and features. What truly sets the 2008 Overland apart, however, is the optional 3.0L CRD (Common Rail Diesel) engine. This powerplant transformed the Grand Cherokee from a capable SUV into an incredibly efficient and potent towing machine, appealing to a niche but dedicated group of enthusiasts who valued both rugged performance and reduced fuel consumption.
The appeal lies in its duality: it’s a comfortable daily driver with a plush interior and premium amenities, yet it retains the legendary Jeep 4×4 capability, ready to tackle challenging terrain. The diesel engine adds another layer of versatility, offering impressive range and substantial towing capacity, making it a compelling choice for adventurers, campers, and anyone needing to haul heavy loads without constantly visiting the gas station.
Under the Hood: The 3.0L OM642 Diesel Engine
The heart of the 2008 Grand Cherokee Overland Diesel is the 3.0-liter V6 turbodiesel engine, code-named OM642, manufactured by Mercedes-Benz. This robust engine was also found in various Mercedes-Benz models of the era, including the ML and GL-Class, as well as the Dodge Sprinter van, showcasing its reliability and versatility across different platforms.
- Power and Torque: This engine typically produced around 215 horsepower and a stout 376 lb-ft of torque. The torque figure is particularly important, as it provides the effortless acceleration and immense pulling power characteristic of diesel engines, especially at lower RPMs.
- Fuel Economy: While official EPA figures for the 2008 diesel Grand Cherokee are hard to pin down precisely due to varying testing methods over time, owners commonly report combined fuel economy figures in the high teens to low twenties (MPG), significantly better than the gasoline V8 options and even competitive with some V6 gasoline models of its size. On highway cruises, it’s not uncommon for owners to see MPG figures approaching 25-28.
- Reliability and Considerations: The OM642 engine is generally considered robust, but like any sophisticated diesel engine, it has specific maintenance requirements and potential failure points. Common issues to be aware of include:
- Oil Cooler Seals: A notorious leak point that can be expensive to fix due to labor involved in accessing the cooler.
- Swirl Flap Motor: Issues with the intake manifold swirl flap motor, often leading to a check engine light.
- Diesel Particulate Filter (DPF): Over time, the DPF can clog, especially with excessive idling or short trips. Regeneration cycles are crucial.
- Glow Plugs: Can fail, especially in colder climates, leading to hard starting.
- Turbocharger Issues: Less common, but possible, particularly if oil changes are neglected.
Regular, diligent maintenance with correct fluids is paramount for the longevity of this engine.
Overland Trim: Luxury Meets Capability
The Overland trim level on the 2008 Grand Cherokee was designed to offer the best of both worlds: rugged capability and premium comfort.
- Interior Amenities: Standard features on the Overland included:
- Premium leather-trimmed seating (often with contrasting piping).
- Heated front seats.
- Power-adjustable pedals.
- Dual-zone automatic climate control.
- MyGIG infotainment system with navigation and a hard drive for music storage.
- Boston Acoustics premium sound system.
- Woodgrain interior accents.
- Power sunroof.
- Exterior Styling: The Overland typically featured chrome accents, unique alloy wheels, and body-color fascias that gave it a more upscale appearance compared to lower trims.
- Capability: Crucially, the Overland trim came standard with Jeep’s Quadra-Drive II 4×4 system. This advanced system includes electronic limited-slip differentials (ELSDs) at both the front and rear axles, providing unparalleled traction in challenging off-road conditions by instantly sending nearly all available torque to the wheel(s) with grip. This makes the Overland Diesel a true performer both on and off the pavement.
What to Look for When Buying a 2008 Jeep Grand Cherokee Overland Diesel
Purchasing a used diesel vehicle, especially one over a decade old, requires careful consideration. A thorough pre-purchase inspection (PPI) by a qualified mechanic familiar with Mercedes-Benz diesel engines is highly recommended.
- Maintenance Records: This is perhaps the most critical factor. A well-documented service history, especially for oil changes (using correct low-ash synthetic oil), fuel filter replacements, and any major repairs, indicates a responsible owner and a potentially healthier engine.
- Engine Specifics:
- Listen for unusual noises: Knocking, ticking, or excessive turbo whine.
- Check for leaks: Pay close attention to the valley of the engine for oil leaks (a tell-tale sign of oil cooler seal failure). Check around the turbo and DPF.
- Exhaust Smoke: A little white smoke on cold start is normal, but excessive black or blue smoke is a red flag.
- DPF Status: If the check engine light is on, scan for DPF-related codes. Inquire about its history. Some owners may have opted for DPF delete kits (illegal in many areas for road use, but common).
- Transmission: Test for smooth shifts through all gears. Check transmission fluid color and smell (should be red, not brown or burnt).
- 4×4 System: Engage 4WD (if safe to do so) and listen for unusual noises from the transfer case or differentials. Check for proper engagement.
- Suspension and Steering: Listen for clunks or squeaks over bumps. Check for excessive play in the steering wheel.
- Electrical Components: Test every button, switch, and feature: windows, sunroof, navigation, radio, HVAC, heated seats, etc.
- Rust: Inspect common areas for rust, especially rocker panels, wheel wells, and the underside of the frame.
- Test Drive: Pay attention to how the vehicle accelerates, brakes, and handles. Listen for road noise, wind noise, and any vibrations. Ensure the vehicle tracks straight.
Owning a 2008 Grand Cherokee Overland Diesel: Pros and Cons
Like any specialized vehicle, there are trade-offs to consider before committing to ownership.
Pros:
- Exceptional Fuel Economy: For its size and capability, the diesel offers impressive MPG.
- Outstanding Torque & Towing: Easily pulls heavy trailers, boats, or campers.
- Luxurious & Comfortable: Overland trim provides a premium driving experience.
- Legendary Off-Road Capability: Quadra-Drive II makes it highly competent off pavement.
- Durability: The OM642 engine is known for long life if properly maintained.
- Unique Factor: A less common and highly sought-after variant.
Cons:
- Higher Maintenance Costs: Diesel-specific parts and labor can be more expensive than gasoline equivalents.
- Potential for Expensive Repairs: Oil cooler seals, DPF, turbo, and swirl flap issues can lead to significant repair bills.
- Fuel Availability/Cost: Diesel fuel can be more expensive than gasoline and less readily available in some areas.
- Age-Related Issues: As a 15+ year old vehicle, general wear and tear items will need attention regardless of powertrain.
- Finding Qualified Mechanics: Not all mechanics are comfortable working on European diesels.
Maximizing Your Investment: Tips for Owners
If you decide to purchase a 2008 Grand Cherokee Overland Diesel, proactive ownership will be key to a rewarding experience.
- Adhere to Service Schedules: Follow the manufacturer’s recommended maintenance intervals strictly, especially for oil and filter changes. Use only specified low-ash, synthetic engine oil (MB 229.51 or equivalent).
- Fuel Quality: Use high-quality diesel fuel, and consider using a fuel additive, especially in colder climates, to prevent gelling and keep the fuel system clean.
- DPF Management: If your driving habits involve short trips, ensure the vehicle gets regular highway runs to allow the DPF to regenerate. If the DPF becomes an ongoing issue, research options (e.g., professional cleaning, or in some regions, DPF delete for off-road use only).
- Find a Specialist: Identify a reputable independent mechanic who specializes in Mercedes-Benz or European diesel engines. They will have the specific tools and expertise required.
- Monitor for Leaks: Regularly check under the hood and on the ground for any signs of fluid leaks. Early detection can save significant money.
- Consider Upgrades: Aftermarket tuning can unlock even more power and efficiency, but research reputable tuners. Suspension upgrades can further enhance off-road capability.
