AUTOSAVER88 Radiator for Jeep Grand Cherokee & Commander 2005–2010 (Manual Trans) — Aluminium Core, High-Density Fins

A direct-fit, high-efficiency replacement radiator for select Jeep Grand Cherokee (2005–2010) and Commander (2006–2010) models equipped with manual transmissions.

If your Jeep is overheating, leaking coolant, or showing signs of a failing cooling system, this AUTOSAVER88 complete radiator offers a reliable aftermarket option engineered to match OE fit and form. Built with an aluminum core and a reinforced plastic tank, the unit is pressure-tested to reduce the risk of leaks and delivers improved heat dissipation through a dense fin design. Before purchase, verify vehicle compatibility and transmission type to ensure correct fitment.

Will this radiator fit my Jeep Commander or Grand Cherokee?

This radiator is manufactured to replace specific OEM part numbers (55116849AC, 55116849AB) and fits 2006–2010 Jeep Commander models and 2005–2010 Jeep Grand Cherokee models with the listed engine sizes. It is designed for manual transmission configurations only and is not compatible with automatic transmissions.

• Compatible engines: 3.0L, 3.7L V6; 4.7L, 6.1L V8
• Confirm OEM part numbers 55116849AC / 55116849AB
• Manual-transmission vehicles only — not for A/T models
• Always check vehicle year, engine, and transmission before ordering

How does this radiator improve cooling performance?

Designed with a high-density, multi-louvered fin pack and an aluminum core, the radiator increases surface area for faster heat transfer. That construction enhances coolant-to-air exchange, helping the engine dissipate heat more effectively under normal driving and heavy loads.

• High-density fins for greater heat rejection
• Aluminum core for efficient thermal conductivity
• Factory-style mounting points for proper airflow alignment

Is the AUTOSAVER88 radiator durable and leak-resistant?

Each radiator undergoes leak testing and uses a heavy-duty plastic tank combined with the aluminum core to resist cracking and corrosion. The build quality is intended to deliver a longer service life compared with poorly made aftermarket units, though careful installation and correct coolant maintenance are essential.

• Pressure-tested for leak prevention
• High-grade plastic tank resists impact and vibration
• Corrosion-resistant aluminum core prolongs lifespan

What comes in the box and how should it be installed?

The package ships with one complete replacement radiator and a user manual; the radiator cap is not included. Because proper coolant system bleeding and secure mounting are critical, professional installation is recommended to avoid damage or improper fitment.

• Included: 1 x complete radiator, 1 x user manual
• Not included: radiator cap, hoses, or transmission cooler lines
• Recommended: professional installation and coolant system flush

Who is this for? Drivers and professional mechanics replacing a failing radiator on compatible Jeep Commander or Grand Cherokee models who need a direct-fit, OE-replacement style part that emphasizes cooling efficiency and leak-tested construction. It's especially suitable for owners looking to restore factory-level cooling performance on manual-transmission Jeeps while maintaining OEM mounting and connections.
