A Legacy of Toughness: The Nissan 620's Origins
The Nissan 620, a compact pickup truck manufactured by Nissan Motors from 1972 to 1979, carved out a significant niche in the automotive market. It was designed to be a practical, durable, and affordable workhorse, and boy, did it deliver. The first generation, introduced in 1972, was a complete redesign from its predecessor, the 520/521 series. Nissan aimed to create a truck that was not only functional but also aesthetically pleasing, and the 620 was their answer. Its styling was characterized by clean lines, a bold grille, and a distinct silhouette that made it instantly recognizable. One of its most defining features was the available "King Cab" configuration, introduced in 1977. This extended cab offered more interior space and a bit more comfort, which was a significant upgrade for truck buyers who needed more than just a basic cab. This innovation helped set the 620 apart from many competitors at the time. The truck was offered in various trims and configurations, including long and short bed versions, catering to a wide range of needs, from light commercial use to personal transportation. Under the hood, the 620 typically featured Nissan's reliable L-series engines, known for their simplicity and longevity. These engines, often the 1.8L or 2.0L inline-four, provided enough power for daily tasks without sacrificing fuel efficiency, making it an economical choice for many owners. The suspension system was designed for durability, capable of handling rough roads and heavy loads, which further solidified its reputation as a dependable vehicle. The overall build quality was excellent, a hallmark of Japanese manufacturing during that era, ensuring that many 620s are still on the road today, a testament to their robust construction. The truck's success wasn't just limited to its home market; it was exported globally and gained popularity in countries like the United States, Australia, and various parts of Asia, where its combination of affordability, reliability, and utility resonated with consumers. The Nissan 620 wasn't just a truck; it was a statement of practicality and enduring quality, laying the groundwork for Nissan's future success in the pickup truck segment. Its legacy is not just about sales figures, but about the lasting impression it left on owners and the automotive culture.
Iconic Design and Features That Endure
When we talk about the Nissan 620, we're talking about a truck with a design that's truly stood the test of time. Its clean, sharp lines and a distinctive front-end treatment, often featuring a chrome grille and quad headlights on certain models, give it a look that's both rugged and surprisingly stylish. It’s the kind of truck that turns heads not because it’s flashy, but because it possesses a classic, understated cool. The profile is classic pickup – strong shoulder lines, a purposeful stance, and a bed ready for work or play. What really set the 620 apart and contributed significantly to its enduring appeal was the introduction of the King Cab option. This wasn't just a little extra space; it was a game-changer for compact trucks. The King Cab provided a noticeably larger interior, offering more legroom and a bit of extra storage behind the seats. For families or individuals who needed a truck for daily driving but also wanted the utility of a pickup bed, the King Cab made the 620 a far more practical and comfortable choice. It bridged the gap between a pure work vehicle and a more versatile daily driver. Beyond the King Cab, the 620 offered other thoughtful features for its time. The bed, available in different lengths, was designed for utility, with sturdy construction that could handle loads. The interior, while basic by today's standards, was functional and driver-focused. Simple, durable materials meant that the cabin could withstand the rigors of daily use, and repairs were generally straightforward, contributing to its longevity. The availability of different engine options, primarily Nissan's reliable L-series inline-four engines (like the 1.8L and 2.0L), provided a good balance of power and fuel economy. These engines are known for their simplicity and ease of maintenance, which is a huge plus for owners who like to work on their own vehicles or keep them running smoothly on a budget. The overall build quality was exceptional, a hallmark of Nissan during this period. These trucks were built to last, with solid chassis and body construction that has allowed many examples to survive in remarkable condition for decades. This inherent durability, combined with its iconic styling and the practical innovation of the King Cab, cemented the Nissan 620's status as a beloved classic. It's a truck that blends form and function seamlessly, offering a driving experience that feels connected and honest. The aesthetic appeal is undeniable, making it a prime candidate for restoration or customization, where owners can further highlight its classic lines and inherent charm. The 620 isn't just a piece of automotive history; it's a testament to smart design and enduring quality that continues to captivate enthusiasts today.
The Heart of the Beast: Engine and Performance
Under the hood of the Nissan 620, you'll find the kind of mechanical heart that defines reliability and simplicity – the legendary L-series engines. For most 620s, you're looking at either the 1.8-liter or the 2.0-liter inline-four gasoline engines. These aren't powerhouse engines designed for drag racing, guys, but they are absolute workhorses. They were engineered by Nissan with durability and fuel efficiency in mind, making the 620 a practical choice for everything from hauling lumber to making the daily commute. The L18 (1.8L) and L20 (2.0L) engines are known for being incredibly robust. They're relatively simple in design, which means they are easier to work on, maintain, and repair. For anyone who enjoys getting their hands dirty with a bit of DIY mechanics, these engines are a dream. Parts are generally available, and the mechanical simplicity means fewer things can go wrong compared to modern, complex engine management systems. Performance-wise, expect dependable, no-frills power. These engines provided enough grunt to get the job done, whether it was accelerating from a stoplight or climbing a moderate incline with a load in the bed. They weren't built for speed, but they were built for endurance and reliability. The sound they produce is a distinctive, steady hum that many enthusiasts associate with the golden age of Japanese pickups. Paired with a manual transmission, often a 4-speed or 5-speed, the driving experience is engaging and connected. You really feel like you're operating a machine, shifting gears and managing the powerband. Automatic transmissions were also an option for those who preferred a more relaxed drive. The suspension, typically a leaf spring setup in the rear and independent front suspension, was designed to handle the rigors of truck life. It's a setup that prioritizes load-carrying capacity and durability over outright comfort, but for its intended purpose, it worked exceptionally well. It provided a stable platform for hauling and kept the ride relatively controlled, even on less-than-perfect roads. The overall performance profile of the Nissan 620 is one of dependable utility. It's a truck that you can count on to start up, run reliably, and get you where you need to go, all while sipping fuel at a reasonable rate. This focus on practical performance and mechanical integrity is a huge part of why the 620 remains so popular among those who appreciate well-built, no-nonsense vehicles. It's a testament to Nissan's engineering prowess that these engines are still ticking after all these years, often with just basic maintenance.

Keeping Your 620 Rolling: Maintenance and Tips
If you're lucky enough to own a Nissan 620, or are thinking about getting one, you know that keeping these vintage trucks in tip-top shape is key to enjoying them for the long haul. Thankfully, the 620 is known for its mechanical simplicity, which makes maintenance and repairs a bit more manageable than with modern vehicles. The core of this truck's powertrain is the Nissan L-series engine, typically the L18 or L20. These engines are renowned for their durability, but like any engine, they require regular attention. Regular oil changes are paramount. Use the correct type and viscosity of oil recommended for your specific engine – check your owner's manual or online forums for guidance. Don't neglect the oil filter either! Beyond oil, keep an eye on your coolant levels and the condition of your hoses and belts. Overheating can be a killer for older engines, so a well-maintained cooling system is non-negotiable. Spark plugs, distributor cap, and rotor are also standard tune-up items that are relatively easy to access and replace on these L-series engines. Fuel filters should also be changed periodically to ensure clean fuel is reaching the carburetor. Speaking of carburetors, many 620s will have a Hitachi or Mikuni carb. These can sometimes be finicky and may require periodic cleaning or adjustment to keep the engine running smoothly. If you're not comfortable with carburetors, finding a mechanic experienced with these older units is a good idea. The drivetrain on the 620 is typically robust, but checking the transmission fluid and differential fluid levels is important. For manual transmissions, clutch wear is something to monitor, and while not a simple DIY job, it's a common repair item. The suspension and brakes are critical for safety. Regularly inspect your brake pads, rotors, and lines. For the suspension, check for worn-out leaf springs, bushings, and shock absorbers. These components are essential for ride quality and handling, especially if you plan on carrying loads. Body and frame rust is probably the biggest enemy of any classic truck, and the 620 is no exception. Thoroughly inspect common rust areas like the wheel wells, rocker panels, cab corners, and the underside of the bed. Addressing rust early is crucial to prevent it from spreading and compromising the structural integrity of the vehicle. Many owners opt for rust-proofing treatments or regular undercoating, especially if they live in areas with harsh winters or salty roads. Electrical systems on older vehicles can sometimes be a source of headaches. Ensure all your lights, signals, and gauges are working correctly. Clean battery terminals and check the condition of wiring harnesses. Sometimes, a simple grounding issue can cause a cascade of electrical problems. Finally, join the community! The Nissan 620 enthusiast scene is filled with knowledgeable people. Online forums, Facebook groups, and local car clubs are invaluable resources for finding parts, getting advice on repairs, and learning about common issues specific to your truck. Don't be afraid to ask questions; most owners are happy to share their experiences and help out fellow enthusiasts. By staying on top of regular maintenance and addressing potential issues promptly, you can ensure your Nissan 620 remains a reliable and enjoyable classic for many years to come.
Finding Your Own Nissan 620: Buyer's Guide
So, you've caught the bug and are looking to snag your very own Nissan 620? Awesome choice, man! These trucks are becoming increasingly collectible, but finding a good one still requires a bit of savvy. Here’s what you need to know to navigate the market and find a gem. First off, know what you're looking for. Are you after a stock, original condition truck? Or are you planning a full-blown custom build? Your intention will heavily influence the type of 620 you should seek out. A solid, original truck might be a better starting point for a restoration, while a project truck with some existing modifications might be perfect for a custom build, provided the work is sound. Inspect thoroughly. This is crucial for any used vehicle, but especially for a classic truck that's likely seen decades of use. Start with the body. Look for rust, rust, and more rust. Pay close attention to the usual suspects: lower door panels, cab corners, rocker panels, around the windows, the bed floor, and especially the frame rails and suspension mounts underneath. Surface rust might be manageable, but significant perforation or structural rust is a major red flag and can be incredibly expensive to repair properly. Check the frame for any signs of damage, bends, or excessive rust. The engine is your next priority. If possible, try to hear it run. Does it start easily? Does it idle smoothly? Are there any obvious leaks (oil, coolant)? Any strange noises? While L-series engines are tough, a truck that hasn't been run or maintained recently will likely need a thorough tune-up, which includes checking compression, ignition system, and fuel system. Test drive it if you can. How does it shift? Does the clutch engage smoothly? Do the brakes feel adequate? Listen for any clunks or rattles from the suspension or drivetrain. Check all the gauges and electrical components. Do the headlights, taillights, turn signals, and wipers work? Are the interior lights functional? Sometimes, even simple things like a working radio or functional AC (if equipped) can be deal-breakers for some buyers. The King Cab advantage. If you're looking for a bit more comfort and space, prioritize finding a King Cab model. These are often more desirable for daily use. Documentation and history. Does the seller have any service records or paperwork for the truck? While not always available for older vehicles, any history can provide insight into its past maintenance and ownership. Price expectations. Nissan 620s can vary widely in price depending on condition, originality, mileage, and whether it's a King Cab. Be prepared to do some research on recent sales to get a sense of fair market value. Don't be afraid to walk away if the price isn't right or if the truck has too many issues that you can't handle. It's better to wait for the right one than to buy a money pit. Patience is key when hunting for a classic truck like the 620. With careful inspection and a bit of luck, you'll find a fantastic example to add to your collection or start your next project!
