CSF 4015 Hybrid Radiator for Toyota Corolla Corolla Cross Prius Prius Prime

The CSF 4015 hybrid radiator is a replacement engine cooling radiator made for Toyota hybrid models. Hybrid cooling systems cycle between electric and combustion operation, which puts repeated thermal stress on the radiator. This part is built with that in mind.

Key Features:

• Upgraded B-Tube design: uses a B-fold tube, formed in the shape of a "B", in place of a standard weld tube. This makes the tube stronger and better able to handle the cyclical load patterns of hybrid systems.
• One part number for six hybrid configurations: covers Full Hybrid (FHEV) and Plug-In Hybrid (PHEV) variants across Corolla, Corolla Cross, Prius and Prius Prime.
• Nitrogen leak tested: CSF pressure-tests its radiators at 150% of operating pressure.
• Radiator cap: not included.

Choose the CSF 4015 as a hybrid radiator replacement for improved long-term durability in demanding hybrid cooling duty.
