Aluminum Radiator for Acura ILX (2013-2015) 2.4L

High-Efficiency 3-Row Aluminum Performance Radiator for 2013-2015 Acura ILX (DE1)

What it Does: The all-aluminum 3-row performance radiator replaces the failure-prone factory cooling unit on the 2013-2015 Acura ILX to eliminate thermal degradation and maintain optimal operating temperatures under load.

The Stock Acura ILX Cooling System Limitation

Factory radiators installed in the DE1 platform utilize plastic composite end tanks crimped onto a thin single-row aluminum core. Over continuous thermal cycling and elevated operating pressures, these molded plastic tanks degrade, embrittle, and hairline crack along the crimp seam or inlet necks. Furthermore, the limited coolant capacity of the stock core easily succumbs to heat soak during aggressive, high-RPM driving, causing coolant temperatures to spike and triggering defensive ECU timing pull.

The Engineering Solution

This drop-in upgrade features an all-aluminum 3-row tube-and-fin core engineered to significantly expand total fluid volume and heat dissipation surface area. By replacing failure-prone crimped plastic with precision 100% TIG-welded structural aluminum end tanks, this assembly resists core fatigue, pressure spikes, and catastrophic burst failures. Internal tube geometry maximizes flow dynamics to counter thermal buildup, keeping high-revving K24Z7 powerplants operating precisely within their optimal temperature threshold. It drops directly into OE mounts with no chassis modification required.

Frequently Asked Questions & Fitment Warnings

Does this fit the DE1 ILX?

Yes, this is a direct fit for the 2013-2015 Acura ILX equipped with the K24Z7 2.4L engine. This product is not a universal radiator and is specified exclusively for the 2.4L applications above; verify hose routing and transmission cooler requirements before purchase.

Do I need to bleed the cooling system after installing this radiator?

Yes, a complete coolant flush, fresh coolant mixture fill, and thorough air-bleed procedure are required to prevent air pockets from damaging your engine.

The Acura Caliber

Engineered for high-revving JDM applications, this all-aluminum core ensures your naturally aspirated VTEC powertrain maintains maximum thermal headroom whether carving backroads or stuck in heavy traffic.
