Northern 209691 Race Pro 28x19 GM Triple Pass Aluminum Radiator

The Northern 209691 Race Pro is a universal-fit, all-aluminum triple pass radiator designed for Chevy and GM racing and high-performance applications. Built for maximum heat dissipation, this radiator passes coolant through the core three times before exiting — delivering significantly greater cooling capacity than standard single or double pass designs.

Key Features:

• Triple pass design — coolant passes through the radiator three times for maximum cooling efficiency
• All-aluminum construction — lightweight and durable for long service life
• Two rows of 1" tubes for optimized coolant flow and heat transfer
• Machined billet aluminum SAE-compliant filler neck for a quality, leak-free seal
• 28" x 19" overall dimensions (total width including tanks x total core height)
• Upper hose connection: 1-1/2" on driver's side
• Lower hose connection: 1-3/4" on passenger's side
• Universal fitment for GM/Chevrolet racing builds

Installation Notes: Due to the triple pass design's higher flow requirements, it is strongly recommended to use 1-to-1 pulleys, a high-volume water pump, and to eliminate any restrictors from the cooling system. Measure your radiator opening carefully before ordering — radiators are non-returnable. Dimensions listed reflect total width including tanks and total core height.
