ILONPA AC Compressor with Clutch for Nissan 3.5L (Maxima/Murano/Pathfinder/Quest) — DKS17D, 7-Groove 115mm Pulley

ILONPA’s complete AC compressor with clutch replaces the factory unit for select 3.5L Nissan Maxima, Murano, Pathfinder, and Quest models, restoring reliable cooling and clutch engagement.

If your Nissan’s air conditioning has lost pressure, is noisy, or the compressor clutch won’t engage, this direct-fit ILONPA replacement is designed to match OE fit and function. Built around a DKS17D compressor core, prefilled with PAG 100 oil and fitted with a 7-groove pulley, the assembly is intended to simplify swap‑outs and return steady cooling performance without extensive modifications.

How does this compressor match my Nissan’s original part?

The ILONPA unit is engineered to replace a wide range of factory and aftermarket part numbers for 3.5L Nissan VQ engines. Its mounting points, pulley size, and electrical clutch connector are designed to align with the original equipment layout so installation uses existing brackets and hoses.

• Replaces many OE and aftermarket numbers including 926001JA0A/926001JA1A and TEM275719
• DKS17D compressor type with 115 mm pulley diameter and 7 grooves
• Prefilled with 140±10 mL of PAG 100 oil for system compatibility

Will this reduce noise and vibration compared with a worn compressor?

Yes — the compressor housing is cast from high‑strength aluminum alloy and the clutch assembly is balanced to minimize NVH (noise, vibration, harshness). That makes cabin sound levels lower and helps avoid the rattles common to older or failing compressors.

• Aluminum alloy body for improved rigidity and heat dissipation
• Balanced pulley and clutch for reduced vibration and quieter operation
• Designed for steady torque transfer to minimize clutch chatter

What are the key specifications and installation reminders?

The compressor ships prefilled with the recommended PAG 100 oil and features the factory-style electrical clutch to simplify swap-in. Before fitting, the vehicle’s AC system must be thoroughly cleaned and evacuated; residual contaminants or leftover cleaning solvents can damage a new compressor.

• Oil type: PAG 100, quantity: 140 ±10 mL
• Pulley grooves: 7; pulley diameter: 115 mm
• Professional installation and system evacuation/recharge recommended for best results

How does this affect fuel economy and longevity?

A properly functioning compressor reduces load inefficiencies and runs smoother, which can modestly improve fuel use during steady driving compared with a failing unit that slips or drags. Durable materials and factory-aligned tolerances help extend service life when the AC system is clean and correctly charged.

• Lower internal friction and improved sealing reduce parasitic load
• Corrosion-resistant aluminum housing extends component life
• Prefilled oil and correct pulley ratio help maintain intended system efficiency

Who is this for: Owners and independent repair shops working on 2009–2014 Nissan Maxima and Murano (3.5L), 2013–2015 Nissan Pathfinder (to 9/14), and 2011–2015 Nissan Quest (to 8/14) who need a direct-fit AC compressor with clutch. This ILONPA unit is suited to technicians replacing a worn or failed compressor, or enthusiasts performing a system refresh — particularly when matching OE part numbers and retaining original bracketry and drive configurations is important. Always have the A/C system flushed, vacuumed, and recharged by a qualified technician to protect the new compressor and ensure safe, reliable cooling.
