AUTOSAVER88 Radiator for Jeep Wrangler 3.6L (2012–2017) & 3.8L (2007–2011) — Manual Fit, Aluminum Core

AUTOSAVER88 complete radiator engineered as a direct-fit, high-density replacement for select Jeep Wrangler V6 models to restore cooling performance.

If your 2012–2017 Jeep Wrangler with the 3.6L engine or a 2007–2011 Wrangler with the 3.8L V6 is running hot, leaking, or has a damaged core, this AUTOSAVER88 radiator is built to bring reliable cooling back to your vehicle. Designed to meet OE fitment standards and to replace part number 55056633AB, this unit installs in manual-transmission applications and uses an aluminum core with high-density multi-louvered fins plus a high-grade plastic tank for long service life.

How does this radiator improve cooling compared to a worn original?

The AUTOSAVER88 radiator uses a high-density, multi-louvered fin design that increases surface area for heat dissipation and improves airflow through the core. That means more efficient heat transfer away from the engine under normal driving and towing conditions. Each radiator is leak-tested to verify sealing integrity before shipment.

• Aluminum core with multi-louvered fins for better heat transfer
• High-grade plastic tank resistant to cracking and corrosion
• Factory-style mounting points for correct airflow alignment
• Pre-shipment leak testing to reduce installation issues

Will this radiator fit my Jeep Wrangler and what should I confirm before ordering?

This radiator is compatible with Jeep Wrangler models that use the specified engines: 2012–2017 Wrangler with the 3.6L and 2007–2011 Wrangler with the 3.8L V6, for manual transmission vehicles only. Confirm your vehicle year, engine code, and transmission type before purchase to ensure direct fit. The unit replaces OEM part number 55056633AB.

• Compatible with 2012–2017 Jeep Wrangler 3.6L (manual)
• Compatible with 2007–2011 Jeep Wrangler 3.8L V6 (manual)
• Not for automatic-transmission models — verify transmission
• OEM reference: 55056633AB for cross-checking

What comes in the box and what additional parts or services are recommended?

The package includes one complete AUTOSAVER88 radiator and a user manual to guide reinstallation. The radiator cap is not included, so plan to reuse a verified good cap or purchase a new one. Professional installation is recommended to ensure proper coolant system bleeding and to confirm no other components (hoses, clamps, thermostat) need replacement.

• Includes 1x complete radiator and 1x user manual
• Radiator cap sold separately — check compatibility
• Consider replacing hoses, clamps, and thermostat while servicing
• Professional installation recommended for best results

How durable and leak-resistant is the AUTOSAVER88 radiator?

Constructed with an aluminum core and a reinforced plastic tank, this radiator is built to endure thermal cycling and road conditions common to off-road and daily driving. Each unit undergoes leak testing before shipment to help ensure longevity and reduce the risk of premature failure. Proper installation and coolant maintenance are still crucial for maximum service life.

• Aluminum core resists corrosion and improves thermal performance
• High-grade plastic tank reduces cracking risk in cold and heat
• Leaktested before shipping to minimize defects on arrival
• Follow recommended coolant and maintenance schedules

Who is this radiator for? This AUTOSAVER88 radiator is aimed at Jeep owners and mechanics who need a reliable, direct-fit replacement for manual-transmission Wranglers with 3.6L (2012–2017) or 3.8L V6 (2007–2011) engines. It’s suitable for people restoring a vehicle, replacing a damaged core after an accident or leak, or upgrading to a fresh OE-equivalent cooling component. If you drive in hot climates, tow frequently, or use your Wrangler off-road, this higher-density core provides improved cooling efficiency — just confirm compatibility and consider professional installation.
