• Aluminum core with plastic tanks for a practical OE-style design.
• Cross-flow layout for efficient coolant routing through the core.
• Single-row core construction with 15.375 in. core height and 28.5625 in. core width.
• Bottom-left outlet and center-left inlet locations for application-specific hose routing.
• No engine oil cooler, no transmission oil cooler, and no radiator cap included.

• Overheating caused by restricted coolant flow or internal radiator wear.
• Cracked plastic tanks or aged hose connection points.
• Cooling system service needs after radiator failure or contamination.

Installation Notes

Verify inlet and outlet locations, core dimensions, and mounting type before installation.
