Why Buy the CU-70315 Combo Unit
The CU-70315 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.
