Installation Notes and Tips

Verify core dimensions, inlet and outlet size, and mounting style before installation. This radiator is listed for Volkswagen Jetta, Golf, and Cabrio models with slot mount on the bottom where noted, including 14 7/8 in. core and 14 in. core applications. Confirm that your vehicle does not require an integrated transmission or engine oil cooler, since this unit does not include either cooler. Part Number 1557 is engineered for drop-in fitment, but cooling system inspection, hose condition checks, and proper bleed procedures should be completed during replacement.

OSC states that its radiators are individually pressure tested and built to OE-style design standards. The manufacturer also notes multi-stage testing during production, including cooler testing before tank installation, core testing before assembly, and final assembly testing after completion.
