28x19x3 All Aluminum Racing Radiator 2-Row Double Pass for Chevy GM

Product Overview

This aftermarket replacement radiator is a double pass, 2-row all aluminum unit measuring 28" x 19" x 3", intended for universal Chevy and GM racing applications. A radiator transfers heat from engine coolant to the surrounding air to support normal operating temperatures. It carries no specific part number in the listing, so buyers should compare dimensions and inlet and outlet locations against the existing radiator before purchase.

Key Features & Performance

• Double pass design routes coolant through the core twice before it returns to the engine, which supports heat exchange in the cooling system.
• Two row core construction provides additional surface area for heat dissipation compared with a single row core of similar size.
• All aluminum construction, as stated in the title, is intended for racing and performance cooling setups.
• Universal fitment means the unit is sized for custom installations rather than a single factory application.
• Overall dimensions of 28" x 19" x 3" allow buyers to check available space in the engine bay before ordering.

Fitment & Compatibility

• for Chevy applications
• for GM applications
• universal mounting, verify dimensions and hose connections against the existing radiator

Common Uses

• Replacing a damaged, leaking, or clogged radiator in a racing or custom build

Frequently Asked Questions

Q: What does a double pass radiator do? A: Coolant enters the tank, travels across the core, reverses direction through the core a second time, and then exits, giving the coolant more contact with the core surface before returning to the engine.

Q: How do I verify fitment? A: Measure the available space in the engine bay and compare the 28" x 19" x 3" dimensions, along with inlet and outlet sizes and positions, against the existing radiator or the intended mounting points.
