Engine Code:
VQ35DE (likely, though specific code for FY33 Q45 is VH45DE for earlier years. VQ35DE was introduced in later models but this manual covers 1997-2001, which could include both. The FY33 chassis code strongly suggests the 4.1L VH45DE V8 for the earlier part of this range, transitioning possibly to the 3.5L VQ35DE in later years of the FY33 generation or a subsequent generation covered within the scope.)
Engine Type:
4.1L V8 DOHC (VH45DE for most of this generation)
Displacement:
4130 cc (4.1 Liters)
Horsepower:
Approximately 270-280 hp @ 6000 rpm (VH45DE)
Torque:
Approximately 280-290 lb-ft @ 4000 rpm (VH45DE)
Fuel Delivery:
Multi-point Fuel Injection (MPI) with electronic throttle control.
Recommended Fuel:
Premium Unleaded Gasoline (91 octane or higher).
Ignition System:
Distributorless Ignition System (DIS) with individual coil-on-plug ignition (or coil packs depending on exact year).
Oil Change Interval:
Typically every 3,000-5,000 miles or 3-6 months, depending on driving conditions. Consult manual for exact recommendation.
Transmission Fluid Interval:
Every 30,000-60,000 miles, or as specified in the manual. Check for severe service intervals.
Spark Plug Replacement:
Platinum-tipped spark plugs often have intervals of 60,000-100,000 miles. Iridium plugs may be longer.
Engine Oil Type:
SAE 5W-30 or 5W-40 Synthetic API SN/SM or equivalent.
Coolant Type:
Nissan/Infiniti Long Life Antifreeze or equivalent silicate-free, ethylene glycol-based coolant.
Power Steering Fluid:
Infiniti Genuine Power Steering Fluid or Dexron III ATF.
Engine Vibration:
Some V8 VH45DE engines can experience engine mount degradation leading to increased vibration.
Timing Chain Tensioner:
While generally robust, some VH45DE engines may eventually require attention to timing chain tensioners or guides.
Idle Air Control Valve:
Can become dirty or faulty, causing rough idle or stalling.
Suspension Wear:
Components like ball joints and bushings can wear over time, affecting ride quality and handling.
