AUTOSAVER88 Radiator for Jeep Commander & Grand Cherokee 2005–2010 (Manual Transmission) — Multi‑Louvered Aluminum Core

AUTOSAVER88 Radiator ATRD1061 is a direct-fit, high-efficiency replacement radiator engineered for manual-transmission Jeep Commander (2006–2010) and Grand Cherokee (2005–2010) models with 3.0L, 3.7L, 4.7L and 6.1L engines.

This complete radiator assembly is designed to match OEM form and function while improving cooling performance through a high-density, multi-louvered aluminum core and durable plastic tanks. It replaces part numbers 55116849AC and 55116849AB and is intended for vehicles equipped with manual transmissions—this unit is not compatible with automatic-transmission configurations. Each radiator is pressure-tested to minimize the risk of leaks and arrives as a ready-to-install assembly (radiator cap not included).

Will this radiator fit my Jeep Commander or Grand Cherokee?

Confirming fitment before purchase is essential. This radiator is made to directly replace factory radiators on model-year ranges listed and specific engine sizes; it was engineered to the same mounting points and hose locations as the OEM part numbers indicated.

• Compatible models: 2006–2010 Jeep Commander; 2005–2010 Grand Cherokee.
• Engine coverage: 3.0L, 3.7L V6; 4.7L, 6.1L V8—manual transmission only.
• OEM replacement numbers: 55116849AC and 55116849AB for cross-reference.
• Not compatible with automatic-transmission (A/T) variants—verify your transmission type.

How does this radiator improve cooling and reliability?

The AUTOSAVER88 unit uses a multi-louvered aluminum core to increase air-to-fluid contact area, which helps dissipate engine heat more efficiently than a worn or clogged original. Robust plastic tanks and a fully pressure-tested assembly lower the chance of early leaks or failures.

• High-density fins boost heat exchange and airflow across the core.
• Aluminum core for lightweight, effective thermal conductivity.
• High-grade plastic tanks tested for leaks and durability.
• Complete radiator assembly arrives ready to install (cap not included).

What should I know about installation and included parts?

The radiator ships as a complete unit with a user manual to guide basic steps, but professional installation is recommended to ensure safe and proper coolant system reassembly. Radiator cap and any ancillary mounting hardware beyond the core assembly may need to be reused from the original unit or purchased separately.

• Package includes one complete radiator and one user manual.
• Radiator cap is not included—reuse your original or buy a compatible cap.
• Intended as a direct-fit replacement following OEM mounting points.
• Professional installation recommended to maintain cooling-system integrity.

How can I verify the right part before I buy?

Double-check your vehicle’s model year, engine displacement, and transmission type against the compatibility list. Use the OEM part numbers to cross-reference with your existing radiator or parts supplier records to avoid ordering the wrong unit.

• Check vehicle VIN or service records to confirm engine and transmission.
• Compare your old radiator’s part number with 55116849AC / 55116849AB.
• Inspect mounting points and hose locations visually if possible.
• Contact a mechanic or parts specialist with your VIN for verification.

Who is this for: This AUTOSAVER88 radiator is aimed at Jeep owners and independent repair shops replacing a failed, leaking or underperforming radiator on manual-transmission Jeep Commander (2006–2010) or Grand Cherokee (2005–2010) vehicles with the specified engine options. It fits drivers who want a direct-fit, OE-referenced replacement that balances cost and durability, and for technicians seeking a pressure-tested assembly that simplifies the swap. If your vehicle uses an automatic transmission, this model is not suitable—verify compatibility before ordering.
