2017 Nissan Frontier Crew Cab

The 2017 Nissan Frontier Crew Cab occupies a unique space in the automotive landscape: a mid-size pickup truck that, despite being relatively unchanged for over a decade, maintains a loyal following. It's a testament to its reliability, capability, and straightforward design. Let's dive into the nitty-gritty of this workhorse, focusing on aspects relevant to car enthusiasts, owners, and hobby mechanics.

Engine Options and Powertrain

The 2017 Frontier Crew Cab offered two engine choices: a 2.5-liter inline-4 and a more popular 4.0-liter V6. Let's break them down:

2.5-Liter Inline-4 (KA24DE Successor)

While less common in the Crew Cab configuration, this engine is a descendant of the venerable KA24DE found in older Nissan 240SX models. However, it's not directly the same. The 2.5L is designed for fuel efficiency and lower-end torque, making it suitable for lighter-duty tasks. Think of it as the "sensible" option. Its output is around 152 horsepower and 171 lb-ft of torque.

From a mechanical perspective, it's a relatively simple engine. It's a Dual Overhead Cam (DOHC) design, meaning it has two camshafts in the cylinder head, allowing for more precise valve control compared to a Single Overhead Cam (SOHC) design like those found in some older Honda Civic engines. This contributes to better efficiency and power.

4.0-Liter V6 (VQ40DE)

This is the star of the show. The VQ40DE is part of Nissan's renowned VQ engine family, known for its smoothness and reliability. It's related to the VQ35DE found in various Nissan and Infiniti models like the 350Z and G35. However, the VQ40DE is specifically engineered for truck duty, with an emphasis on low-end torque – crucial for towing and hauling. Expect around 261 horsepower and 281 lb-ft of torque.

What makes the VQ40DE special? Several things:

Aluminum Block and Heads: This reduces weight, improving fuel economy and handling.
Continuously Variable Valve Timing Control System (CVTCS): Similar to Honda's VTEC or BMW's VANOS, CVTCS adjusts the valve timing based on engine speed and load. This optimizes power delivery across the RPM range. Think of it as giving the engine the best "breathing" for every situation.
Chain-Driven Camshafts: Unlike belt-driven camshafts (which require regular replacement), timing chains are generally more durable and last longer.

Both engines could be paired with either a 5-speed manual transmission (mostly with the 4-cylinder) or a 5-speed automatic transmission. The automatic is the more common choice, especially in the Crew Cab.

Suspension and Drivetrain

The Frontier utilizes a body-on-frame construction, a traditional truck design where the body sits on top of a separate ladder frame. This provides excellent strength and durability, making it suitable for off-road use and heavy loads. Think of older Chevy Silverados or Toyota Tacomas – they all share this basic architecture.

The front suspension is a double-wishbone design with coil springs. This setup provides good handling and ride quality for a truck. It's similar in principle to what you might find in a sports car like a Mazda Miata, although obviously beefier and tuned for truck applications. The rear suspension uses leaf springs, a classic truck suspension design known for its ability to handle heavy loads. While leaf springs might not offer the most refined ride, they are incredibly durable and reliable.

The 2017 Frontier Crew Cab was available in both rear-wheel drive (RWD) and four-wheel drive (4WD). The 4WD system is a part-time system, meaning it's not designed to be used on dry pavement. It engages the front axle for added traction in slippery conditions like snow, mud, or loose gravel. Think of it as similar to the 4WD systems in older Jeep Wranglers or Toyota 4Runners.

The 4WD system utilizes a transfer case to split power between the front and rear axles. It typically offers two modes: 4HI (high range) for general off-road use and 4LO (low range) for extreme situations requiring maximum torque. Engaging 4LO significantly reduces the gearing, multiplying the engine's torque output at the wheels. This is essential for crawling over rocks or pulling a heavy load out of a ditch.

Braking System

The Frontier features disc brakes in the front and drum brakes in the rear. Disc brakes offer superior stopping power compared to drum brakes, which is why they are used on the front axle, where most of the braking force is applied. Drum brakes, while less powerful, are more cost-effective and simpler to maintain.

The system is equipped with Anti-lock Braking System (ABS), which prevents the wheels from locking up during hard braking, allowing the driver to maintain steering control. Electronic Brake-force Distribution (EBD) is also standard, which automatically adjusts the braking force between the front and rear wheels based on load and road conditions, optimizing braking performance.

Common Issues and Maintenance

While the 2017 Frontier is generally considered reliable, there are a few common issues to be aware of:

Timing Chain Tensioner (VQ40DE): Some owners have reported issues with the timing chain tensioner on the VQ40DE, leading to a rattling noise on startup. Replacing the tensioner can resolve this issue.
Radiator Failure ("Strawberry Milkshake of Death"): This is a less common but serious issue that can occur on some Frontier models with automatic transmissions. The transmission cooler inside the radiator can fail, allowing coolant to mix with transmission fluid. This creates a pink, milky substance that can destroy the transmission. Regularly inspecting the coolant and transmission fluid can help prevent this. Consider bypassing the radiator's transmission cooler with an aftermarket unit.
Rust: Like many trucks, the Frontier is susceptible to rust, particularly in areas with harsh winters and road salt. Regularly washing and waxing the truck, and applying rustproofing treatments, can help prevent rust formation.

Maintenance is key to keeping your Frontier running smoothly. Regular oil changes (every 5,000 miles with synthetic oil is recommended for the VQ40DE), filter replacements, and fluid checks are essential. The timing chain on the VQ40DE is generally very durable, but it's a good idea to have it inspected around 100,000 miles. Also, pay attention to the brakes and replace them as needed.

Practical Takeaways

Engine Choice: If you need a truck for heavy hauling and towing, the V6 is the clear choice. If you're primarily using the truck for commuting and light-duty tasks, the 4-cylinder might suffice, but be prepared for slower acceleration.
4WD Considerations: Remember that the 4WD system is part-time, so don't use it on dry pavement. Engage 4LO only when necessary, as it puts a lot of stress on the drivetrain.
Maintenance Matters: Regular maintenance is crucial for preventing major problems. Pay particular attention to the cooling system and transmission fluid to avoid the "strawberry milkshake of death."
DIY Potential: The Frontier's straightforward design makes it relatively easy to work on for hobby mechanics. Tasks like oil changes, brake pad replacements, and filter changes are well within the capabilities of a competent DIYer.
Rust Prevention: If you live in an area with road salt, invest in rustproofing treatments and regularly wash the undercarriage of the truck.

The 2017 Nissan Frontier Crew Cab offers a compelling combination of capability, reliability, and value. While it may not be the most technologically advanced truck on the market, its proven design and robust construction make it a solid choice for those seeking a dependable mid-size pickup.
