Nv Nissan Passenger For Sale

So, you're eyeing an NV Nissan Passenger van for sale? Excellent choice. These vans are workhorses, and with the right knowledge and a bit of elbow grease, they can be incredibly versatile vehicles. Let's dive into the technical aspects you need to consider before making a purchase, turning you from a potential buyer into an informed owner.

Engine Options: A Deep Dive

The NV Passenger van primarily comes with two engine options, each with its own strengths and weaknesses. Understanding these differences is critical.

4.0L V6 (VQ40DE)

The 4.0L V6, designated VQ40DE, is a Nissan staple. You'll find it in many of their trucks and SUVs. It's known for its reliability and decent power output, typically around 261 horsepower and 281 lb-ft of torque.

Key Technical Points:

Camshaft Configuration: This engine uses a Dual Overhead Camshaft (DOHC) configuration with four valves per cylinder. DOHC allows for better valve control and higher RPM operation compared to Single Overhead Camshaft (SOHC) designs.
Variable Valve Timing (VVT): The VQ40DE incorporates Variable Valve Timing. Specifically, it uses Continuously Variable Valve Timing Control System (CVTCS) on the intake valves. CVTCS optimizes valve timing based on engine speed and load, improving fuel efficiency and low-end torque.
Electronic Throttle Control (ETC): ETC, sometimes referred to as "drive-by-wire," replaces the traditional mechanical linkage between the accelerator pedal and the throttle body with electronic sensors and actuators. This system allows the Engine Control Unit (ECU) to precisely control the throttle opening, enhancing fuel economy and throttle response.
Common Issues: The VQ40DE, while reliable, isn't without its quirks. Watch out for timing chain rattle, particularly on higher mileage examples. The plastic timing chain guides can wear down, leading to slack in the chain and potential damage. Also, keep an eye on the coolant temperature sensor, as failures can cause erratic engine behavior. Regularly changing the oil (every 3,000-5,000 miles) with a high-quality synthetic blend is crucial for longevity.

5.6L V8 (VK56DE)

For those needing serious hauling power, the 5.6L V8, the VK56DE, is the beast you want. This engine delivers substantial power, typically around 317 horsepower and 385 lb-ft of torque (although earlier models may have slightly different power figures). This is the engine to choose if you plan on towing regularly or carrying heavy loads.

Key Technical Points:

Construction: This engine is built with an aluminum block and cylinder heads, helping to reduce weight compared to an all-iron engine. It's a significant factor in improving the van's overall performance.
Intake Manifold: The VK56DE features a variable intake manifold. This system uses electronically controlled flaps to change the length of the intake runners, optimizing airflow for different engine speeds. Shorter runners improve high-RPM power, while longer runners boost low-end torque.
Fuel Injection: This engine utilizes sequential multi-port fuel injection (SMPI). Each cylinder has its own fuel injector positioned near the intake valve, allowing for precise fuel metering and efficient combustion.
Common Issues: Like the VQ40DE, regular oil changes (again, every 3,000-5,000 miles with a synthetic blend) are paramount. Watch for exhaust manifold leaks, which are a relatively common issue. These leaks can cause a noticeable ticking sound, especially when the engine is cold. Also, pay attention to the condition of the spark plugs. Replacing them at the recommended interval (typically every 100,000 miles) is essential for maintaining optimal performance. Consider the transmission cooler lines. These lines can be prone to leaks. Inspect them thoroughly.

Which engine is right for you? If you primarily need the van for light-duty passenger transport and prioritize fuel economy, the V6 is a solid choice. If you're planning on heavy hauling or towing, the V8 is the clear winner, despite the increased fuel consumption.

Transmission: A Crucial Component

The NV Passenger van is typically equipped with a 5-speed automatic transmission (earlier models) or a 7-speed automatic transmission (later models). Understanding the transmission's health is paramount before buying.

Key Considerations:

Fluid Condition: Check the transmission fluid. It should be bright red and have a sweet smell. Dark or burnt-smelling fluid indicates potential problems. Consider having a transmission fluid analysis performed by a lab to check for excessive wear metals.
Shift Quality: Pay close attention to the shifting. Look for smooth, consistent shifts without any hesitation or jerking. Slipping or harsh shifts are signs of trouble.
Torque Converter: The torque converter is a fluid coupling that transfers power from the engine to the transmission. Listen for any unusual noises from the torque converter area, such as whining or rattling. Stalling issues could also indicate torque converter problems.
Maintenance History: Ask about the transmission's maintenance history. Has the fluid ever been changed? When was the last time? A well-maintained transmission is far less likely to give you problems. Regular fluid changes (every 30,000-60,000 miles, depending on usage) are critical for longevity.

Suspension and Brakes: Handling the Load

Given the NV Passenger's size and weight, the suspension and brakes are crucial for safe and comfortable operation. Inspect these components thoroughly.

Suspension:

Shocks and Struts: Check for leaks around the shocks and struts. Bounce the vehicle to see if it settles quickly or continues to bounce excessively. Worn shocks and struts can negatively affect handling and ride quality.
Bushings: Inspect the suspension bushings for cracks or wear. Worn bushings can cause clunking noises and sloppy handling.
Leaf Springs (Rear): The rear suspension typically uses leaf springs. Check for broken or sagging leaves. Sagging leaf springs indicate that the vehicle has been consistently overloaded.

Brakes:

Rotor and Pad Condition: Inspect the brake rotors for scoring or warping. Check the brake pad thickness. Insufficient pad thickness is a safety hazard.
Brake Lines: Inspect the brake lines for corrosion or leaks. Replace any damaged brake lines immediately.
Brake Fluid: Check the brake fluid level and condition. Dark or contaminated brake fluid should be flushed and replaced.
ABS System: If the vehicle is equipped with ABS, make sure the ABS warning light is not illuminated. Test the ABS system by performing a hard stop on a safe surface. You should feel the ABS pulsing.

Electrical System: Staying Connected

The NV Passenger van has a complex electrical system. Thoroughly check all electrical components.

Key Checks:

Battery: Check the battery's voltage and condition. A weak battery can cause numerous electrical problems. A load test can reveal the battery's ability to hold a charge under load.
Alternator: Verify that the alternator is charging correctly. Use a multimeter to measure the voltage at the battery terminals with the engine running. It should be around 13.5-14.5 volts.
Wiring Harnesses: Inspect the wiring harnesses for damage, corrosion, or loose connections. Rodent damage is a common issue.
Lights and Accessories: Check all lights (headlights, taillights, brake lights, turn signals) and accessories (power windows, power locks, radio, air conditioning) to ensure they are functioning properly.
OBD-II Scanner: Connect an OBD-II scanner to the vehicle's diagnostic port and check for any stored trouble codes. These codes can provide valuable clues about potential problems. Pay particular attention to any codes related to the engine, transmission, or ABS system.

Body and Chassis: Rust is the Enemy

Rust is a major concern, especially in areas that experience harsh winters. Thoroughly inspect the body and chassis for rust.

Areas to Focus On:

Frame: Check the frame rails for rust, especially around suspension mounting points.
Rocker Panels: Rocker panels are notorious for rusting.
Wheel Wells: Inspect the wheel wells for rust and corrosion.
Floor Pans: Check the floor pans for rust, especially in the front footwells.
Seams and Joints: Pay close attention to seams and joints, as these are common areas for rust to start.

Remember, surface rust is often cosmetic, but deep, penetrating rust can compromise the structural integrity of the vehicle. Consider having a professional inspection if you suspect significant rust damage.
