Why Buy the CU-70316 Combo Unit

The CU-70316 is a complete ComboUnit, a single bolt-in cooling assembly rather than a bare radiator. It ships as one factory-assembled package: Aluminum Radiator, 16.00" SPAL Fan, Fan Shroud, Wiring Harness, Temp Sender, Integrated Trans Cooler, and Radiator Cap. Buying it as a ComboUnit means you install one matched assembly instead of sourcing a radiator, fans, and shroud separately and hoping they fit together.

Matched airflow SPAL fans deliver max air flow to the core and are rated at TRUE CFM.
Aluminum Shroud The perfectly molded shroud delivers superior air flow to the full core at low speeds and idle when you need it most.
One part number Complete cooling package with a single part number.
Rated for the build Sized to cool engines with an est. max HP of 750.
