Common Cooling Issues This Radiator Addresses
- Coolant temperature rise from a restricted or aging radiator core
- Leaks caused by cracked plastic tanks or worn core seams
- Reduced heat rejection from a damaged or inefficient factory radiator
- Fitment problems when replacing the original Hyundai Tucson or Kia Sportage radiator
- Cooling system service needs after corrosion, impact damage, or long-term wear
Installation Notes and Tips
Verify inlet and outlet orientation before installation: the inlet is on the right and the outlet is on the left. Confirm the radiator dimensions and hose routing against the original unit, and transfer any required OE components from the existing cooling system as needed. Because the cap is not included, reuse or replace the radiator cap separately if your vehicle uses one.
