Common Cooling System Issues

• Cracked or leaking radiator tanks
• Reduced coolant flow from an aging radiator core
• Transmission fluid temperature concerns tied to a failing cooler circuit
• Overheating caused by internal radiator deterioration
• Cooling system service needs on Subaru Impreza, Subaru Baja, or Saab 9-2X

Installation Notes

Verify core dimensions, inlet and outlet size, and transmission cooler connections before installation. Confirm vehicle fitment by year, make, and model, especially on 2002-2007 Subaru Impreza, 2005-2006 Saab 9-2X, and 2004-2006 Subaru Baja applications. Inspect hoses, clamps, and coolant condition during radiator replacement to help complete the repair correctly.
