What It Helps Fix

• Coolant leaks from a cracked or aging radiator
• Overheating caused by restricted coolant flow
• Transmission fluid cooling issues tied to a failed internal cooler
• Damaged inlet or outlet necks on the original radiator
• Cooling system service needs on a 1993-1998 Subaru Impreza

Installation Notes and Tips

Verify inlet and outlet sizes, core dimensions, and transmission cooler connections before installation. Flush the cooling system, inspect hoses and clamps, and confirm the radiator mounts and fan clearance match the vehicle before final assembly. For Subaru Impreza service, A1574 should be compared against the original radiator to confirm transmission cooler routing and connection style.
