The 2008 Kenworth T600 is a Class 8 heavy-duty truck, known for its distinctive aerodynamic “anteater” hood design. Introduced in the late 1980s, the T600 series evolved significantly over its production life, with the 2008 model representing a mature iteration. Key trims often centered around engine and chassis configurations, rather than distinct lifestyle-oriented packages. New pricing for a T600 in 2008 could range widely from $100,000 to over $150,000 depending on specifications. Its popularity stems from its reputation for fuel efficiency and driver comfort, making it a favored choice for owner-operators and fleet managers alike.
The Good
The 2008 Kenworth T600 excels in fuel efficiency, crucial for practical cost savings. Its legendary reliability ensures minimal downtime, a vital asset for any professional driver. The comfortable, driver-focused cabin appeals emotionally and practically, enhancing productivity. Its distinctive, aerodynamic design also contributes to its enduring appeal and value.
The Bad
Potential weaknesses for the 2008 Kenworth T600 include the complexity of its advanced aerodynamics, which can make some repairs more intricate. Older models may also experience typical wear and tear on components like suspension and braking systems. Early adoption of some emission systems could also present maintenance challenges compared to later iterations.
2008 Kenworth T600: Quick Overview
- Engine Options: The 2008 Kenworth T600 was primarily equipped with PACCAR MX engines, Cummins ISX, and ISMe, or Caterpillar C15 engines. These were robust, heavy-duty diesel powerplants designed for long-haul applications.
- Horsepower: Horsepower typically ranged from approximately 370 hp to over 550 hp, depending on the specific engine model and configuration chosen by the original buyer. Higher horsepower variants were common for demanding routes or heavier loads.
- Fuel Economy: Fuel economy for a Class 8 truck like the T600 is highly variable and measured in miles per gallon (MPG). With its aerodynamic design, the T600 was considered one of the more fuel-efficient options in its class, often achieving between 5.5 to 7.5 MPG under optimal conditions and load. Factors like gearing, route, driving style, and maintenance significantly impact this.
- 0-60 Times: 0-60 mph times are not a relevant metric for heavy-duty commercial trucks like the Kenworth T600, as their purpose is sustained hauling at highway speeds, not rapid acceleration. Performance is measured in ability to maintain speed under load and on inclines.
- Towing Capacity: The towing capacity of the 2008 Kenworth T600 is substantial, typically rated for Gross Combination Weight Ratings (GCWR) of up to 80,000 lbs or more. This allows it to haul various types of heavy trailers, including dry vans, reefer trailers, flatbeds, and tankers. Specific configurations could achieve even higher ratings.
- Trim-Level Features: While Kenworth doesn't use traditional automotive trim levels, features were highly customizable. Common configurations included various cab and sleeper lengths (e.g., 36-inch, 62-inch, 72-inch sleepers), premium interior materials, enhanced driver amenities like comfortable bunk beds and storage, advanced climate control systems, and a range of available axle configurations (tandem or tridem drive) and suspension types to suit different hauling needs and terrains. Aerodynamic enhancements like fairings and chassis skirts were standard or optional features.

What Problems Does the 2008 Kenworth T600 Have?
The 2008 Kenworth T600, like most heavy-duty trucks of its era, is generally known for robust reliability. However, certain issues are more commonly reported by owners. One area of concern can be related to the exhaust gas recirculation (EGR) system and diesel particulate filters (DPF), especially with the adoption of stricter EPA emission standards around this period. These systems, while aimed at reducing emissions, can become clogged or experience sensor failures, leading to reduced engine performance, warning lights, and costly repairs if not maintained properly. Some owners have reported issues with the engine control module (ECM) or related wiring harnesses, which can manifest in various drivability problems or diagnostic codes.
Another area to watch for, particularly on higher-mileage units, is wear and tear on the cooling system. Radiators, water pumps, and hoses can degrade over time, leading to overheating. The transmission, while typically durable (often an Eaton Fuller manual or an Allison automatic), can also experience issues related to clutch wear (for manuals) or mechatronic unit failures (for automatics) if subjected to extreme use or poor maintenance.
While specific recalls for the 2008 model year might vary and are best checked with Kenworth or the NHTSA database using the VIN, common recalls for heavy-duty trucks of this era could involve braking system components, steering linkages, or electrical system issues. Long-term reliability is strongly dependent on the owner's maintenance regimen. Regular oil changes, fluid checks, filter replacements, and timely attention to any emerging diagnostic trouble codes are paramount. Trucks that have been meticulously maintained and have had proactive repairs are far more likely to offer continued reliable service than those that have been neglected. The aerodynamic design, while beneficial, can also mean that components related to these fairings and panels might require attention to prevent damage or ensure proper function.

How long will the 2008 Kenworth T600 last?
Based on owner data and typical usage patterns for heavy-duty trucks, a 2008 Kenworth T600, with consistent and proper maintenance, can realistically achieve 750,000 to over 1,000,000 miles in its service life. Many owner-operators and fleets aim to keep these trucks running for a decade or more, accumulating significant mileage annually. The long-term durability of the T600 is one of its defining strengths, often outlasting many of its competitors due to its robust construction and PACCAR's reputation for engine reliability. Weaknesses that emerge over time are typically related to wear and tear on components like suspension parts, the driveline, and the aforementioned emission control systems. However, with diligent maintenance, these trucks are known to remain workhorses for hundreds of thousands of miles.
What Technology & Safety Features are Included?
The 2008 Kenworth T600, being a commercial vehicle, prioritizes functionality, durability, and driver comfort over cutting-edge consumer-grade tech. Built-in technology was focused on operational efficiency and diagnostics. Standard features often included a digital tachograph, basic AM/FM radio, and a 12V power outlet. Optional upgrades could include a more advanced stereo system with CD player, satellite radio capability, and potentially a CB radio.
Driver-assistance features in 2008 were relatively rudimentary compared to today's standards. Antilock Braking Systems (ABS) were commonly standard for safety and stability. Some models might have offered optional electronic stability control (ESC) or lane departure warning systems, but these were not as widespread or sophisticated as modern iterations. Cruise control was a standard or widely available option.
Safety features focused on the core structural integrity of the cab and essential braking systems. The robust construction of the Kenworth cab was designed to protect the driver in the event of an incident. Visibility from the driver's seat was generally excellent due to the large windshield and side mirrors, aided by the distinctive long hood that provided a clear view of the road ahead. Air brakes were standard, offering strong stopping power.
Crash-test ratings are not typically conducted or published for heavy-duty commercial trucks like the Kenworth T600 in the same way they are for passenger vehicles by organizations like the NHTSA or IIHS. The emphasis in this vehicle class is on operational safety, durability, and compliance with commercial vehicle regulations. The design and engineering are focused on preventing accidents through driver ergonomics and robust mechanical systems, and on protecting the occupants in the event of a collision through reinforced cab structures and advanced restraint systems where applicable.
