KAX AC Compressor with Clutch for Toyota & Lexus 3.5L Vehicles — Prefilled PAG46, 7‑Groove Pulley

The KAX 98315 AC compressor with clutch is a direct-fit replacement designed to restore air conditioning performance in compatible Toyota and Lexus 3.5L vehicles.

This heavy-duty replacement compressor kit arrives prefilled with PAG 46 oil, includes the clutch assembly, and matches factory mounting and pulley specifications so installation is straightforward for professional mechanics and experienced DIYers. Built from high-strength aluminum, the unit aims to resist corrosion and leakage while supplying the pressure required for reliable cabin cooling across the specified model years.

Will this compressor fit my vehicle?

Compatibility is limited to specific Toyota and Lexus 3.5L models across several year ranges. Before purchasing, confirm your vehicle's year, make, model, and engine trim against the fit list to avoid returns or incorrect installation.

• Fits Lexus RX350 (2010–2015) and ES350 (2013–2018).
• Fits Toyota Sienna (2011–2016, specific ranges noted), Highlander (2011–2013 3.5L), Avalon (2013–2018 3.5L), Camry (2012–2017 3.5L).
• Cross-references common OEM part numbers (e.g., 98315, 88320-0xxxx variants); always verify against your vehicle VIN or factory part number.

What are the key technical specs and why they matter?

The KAX unit mirrors several factory dimensions and operating parameters to ensure correct belt alignment and clutch engagement. Pulley groove count, diameter, oil type, and electrical requirements determine compatibility and long-term reliability when installed correctly.

• Pulley: 7 grooves, 4.53-inch diameter for correct belt fit and tension.
• Electrical: 12V clutch designed for standard automotive electrical systems.
• Prefilled with PAG 46 oil for R134a refrigerant applications; noise level ~60–70 dB under normal load.

How durable and serviceable is this compressor?

Constructed mainly from premium aluminum, the compressor resists cracking and corrosion common in cast components. The kit includes the clutch and arrives oil-preloaded, which reduces handling steps during installation and helps ensure initial lubrication.

• High-strength aluminum housing for long-term structural integrity.
• Clutch included so you won’t need separate sourcing of mating parts.
• Engineered for stable cooling pressure to reduce engine load and improve AC responsiveness.

How should I prepare for installation?

Proper installation requires matching the unit to your vehicle and following recommended service practices: evacuate and recover refrigerant, replace receiver/drier or accumulator, check belt condition, and verify electrical connections. If you’re not experienced with automotive AC work, have a certified technician perform the replacement.

• Confirm fit via year/make/model/trim selector or VIN before ordering.
• Recover refrigerant and replace dryer/accumulator during service to avoid contamination.
• Test system pressures and electrical clutch engagement after installation.

Who is this for: The KAX 98315 compressor kit is aimed at owners of the listed Toyota and Lexus 3.5L vehicles who need a direct replacement compressor and clutch—either to return cooling performance after failure or as part of a thorough AC system overhaul. It suits professional installers and knowledgeable DIY mechanics who will confirm compatibility, follow refrigerant-handling regulations, and perform the necessary system flushing and component replacements for a durable repair.
