Triple Pass Radiator 19x28

The ALLSTAR PERFORMANCE Triple Pass Radiator 19x28 (part number ALL30047) is a purpose-built aluminum cooling core engineered for high-performance engine cooling in custom hot rods, street machines, and competition vehicles. With its triple-pass internal design, this radiator optimizes coolant dwell time through the core, maximizing heat rejection and maintaining stable operating temperatures under sustained high-RPM conditions where conventional single or dual-pass units fall short.

This aluminum radiator measures 28 inches wide by 19 inches tall by 2.25 inches deep, with driver-side inlet and passenger-side outlet configuration. The triple-pass core design forces coolant through multiple pathways, dramatically increasing contact surface area and heat transfer efficiency. This specification matters in real-world applications: street rodders and performance engine builders choose triple-pass cores when pushing higher displacement engines, forced induction setups, or extended track use where cooling margin matters. The compact 2.25-inch depth integrates into tight engine bays common to classic chassis restorations and modern swap applications.

Builders working with carbureted or fuel-injected engines in the 350–500+ horsepower range will recognize this core as a proven solution for serious cooling demands. The natural aluminum finish accepts anodizing or powder coating, allowing seamless integration into show-quality builds or purely functional restorations. Inlet/outlet positioning is critical during engine bay layout—the driver-side inlet pairs with passenger-side outlet, so plumbing configuration must match your specific water pump and thermostat housing orientation during installation.

Triple-pass radiators command a distinct place in the cooling hierarchy. Unlike two-pass designs optimized for compact efficiency, triple-pass cores prioritize maximum heat rejection for engines operating at sustained elevated temperatures. This radiator's proven performance lineage from ALLSTAR PERFORMANCE—a recognized name in hot rod and performance cooling solutions—makes it a direct specification choice for builders who have already selected their core type and are sourcing the exact fit.
