Radiator for Mazda CX-5 (2013-2022) 2.0L 2.5L

Direct-Fit Replacement Engine Radiator for 2013-2022 Mazda CX-5 (KE/KF)

What it Does: The direct-fit replacement radiator stabilizes engine coolant temperatures on the 2013-2022 Mazda CX-5 to prevent thermal overloading, warping, and catastrophic engine overheating under load.

The Stock Mazda CX-5 Thermal Fatigue and Tank Failure

The factory cooling unit in the Mazda CX-5 experiences high-cycle thermal degradation over prolonged operation. Factory plastic composite end tanks continuously undergo thermal expansion and contraction cycles alongside high cooling system pressure. Over time, these structural stresses embrittle the crimped polymer tanks, resulting in stress fractures, weeping tank seams, or structural blowouts near the inlet and outlet necks. Simultaneously, internal tube scaling and exterior road debris build up across the fine aluminum fins, inducing heat soak and degrading heat dissipation efficiency for the high-compression SkyActiv-G engine.

The Engineering Solution

Engineered to restore factory heat rejection tolerances, this replacement radiator features a brazed aluminum single-row core paired with heavy-duty thermal-resistant plastic end tanks. High-density louvered aluminum fins optimize boundary layer airflow dynamics across the 28-5/8 x 16-3/4 x 5/8 inch core, accelerating latent heat dissipation into ambient air. The plastic end tanks are mechanically crimped with high-grade elastomeric gaskets to withstand extreme thermal expansion and internal operating pressures. Each unit undergoes rigorous factory helium and hydrostatic pressure testing to ensure 100% leak-free sealing before leaving the line, directly interchanging with PE0115200A and PE0115200B.

Frequently Asked Questions & Fitment Warnings

Does this fit the KE/KF CX-5?

Yes, this is a direct fit for the 2013-2022 Mazda CX-5 equipped with the SkyActiv-G 2.0L and 2.5L naturally aspirated engines.

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

Yes, all residual air must be completely purged from the closed cooling loop following refill to prevent localized hot spots and boiling cavitation.
