Performance Radiator for Mitsubishi Eclipse (2000-2005) 3.0L Manual

Dual-Core Aluminum Performance Radiator for 2000-2005 Mitsubishi Eclipse

What it Does: Upgrades the factory cooling circuit to a high-capacity dual-row all-aluminum core designed to eliminate heat soak and maintain stable coolant temperatures under aggressive driving.

The Stock Eclipse End-Tank Fatigue

The OEM cooling assembly relies on crimped plastic end tanks bonded to a thin single-row core. Over repeated thermal cycles, the factory composite tanks become brittle, causing hairline fractures at the inlet neck and failure along the crimped perimeter seals. Furthermore, the limited core volume struggles to shed excess thermal load under high-load conditions, resulting in rapid heat soak and engine temperature spikes.

The Engineering Solution

This direct-fit unit features 100% TIG-welded aircraft-grade aluminum construction, eliminating failure-prone plastic end tanks and mechanical crimp seals entirely. Built with an expanded 2-row brazed tube-and-fin core, it significantly increases fluid capacity and heat-dissipating surface area. The fin geometry optimizes ambient airflow transfer without restricting through-core draft, ensuring reliable thermal regulation under severe operational duty.
