The integrated oil cooler and OE-style construction support factory-style cooling system service without changing the vehicle’s original radiator design.
Common Problems This Radiator Addresses
- Coolant leaks from aging plastic tanks
- Reduced cooling efficiency from a clogged or damaged core
- Overheating caused by a failing factory radiator
- Transmission or engine cooling concerns tied to radiator wear
- Fitment issues from incorrect replacement radiator dimensions
Installation Notes and Tips
Verify inlet and outlet orientation before installation: inlet is 1 5/16 in. on the right and outlet is 1 1/2 in. on the left. The application notes specify use of a Micro, 13 psi cap, and the radiator does not include a cap. Confirm all hose connections, cooler line routing, and mounting points against the original unit before final assembly.
Quality Assurance
CSF manufactures radiators to ISO/TSO-certified factory standards and validates cooling performance through laboratory wind tunnel testing. The brand has supplied radiators worldwide for more than 50 years and produces a broad range of OE-style cooling components for major vehicle applications.
