Lower Radiator Hose 1-3/4 x 19

The ALLSTAR PERFORMANCE Lower Radiator Hose 1-3/4 x 19 (ALL30226) is a replacement cooling system component engineered for high-performance engines that demand reliable fluid circulation. This 19-inch lower radiator hose features a 1.75-inch inner diameter and is constructed from durable black rubber designed to withstand sustained coolant flow under operating temperatures. Built to OEM specifications, this hose serves as a critical component in any engine bay where cooling efficiency directly impacts performance and longevity.

The 1-3/4 inch diameter delivers adequate flow capacity for mid-range and high-performance engine applications without creating unnecessary back pressure in the cooling circuit. The 19-inch length provides fitment flexibility across various platform configurations while the reinforced rubber construction resists degradation from thermal cycling and coolant chemistry. ALLSTAR PERFORMANCE's manufacturing standards ensure consistent wall thickness and proper internal geometry to prevent collapse under vacuum conditions—a common failure point in inferior replacement hoses.

This lower radiator hose replacement addresses the needs of engine builders, race teams, and enthusiasts performing cooling system restoration or upgrading to higher-flow configurations. Whether rebuilding a classic engine or refreshing a cooling system after extended service, this hose provides the dimensional accuracy and material quality required for reliable operation. Installation is straightforward using standard hose clamps, and the neutral black finish integrates seamlessly into any engine bay aesthetic. Check fitment against your specific platform's radiator outlet and water pump inlet dimensions before ordering.
