Product Description

The Mishimoto MMRAD-T1-19 Performance Aluminum Radiator is engineered for the T1-platform 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 equipped with the supported 5.3L or 6.2L V8 engines. It replaces the factory radiator with a TIG-welded aluminum assembly designed to provide increased durability, cooling capacity, and resistance to cracking and leaks. The application-specific design retains the factory radiator location and mounting arrangement.

The radiator provides a 119% increase in core volume and a 31% increase in fluid capacity compared with the stock unit. Its 7-row internal oil cooler improves oil heat transfer over the factory 6-row design, while strutted tubes along the upper and lower rows increase rigidity during vibration and chassis flex. Rear-core foam helps seal the fan shroud against the radiator, directing airflow through the cooling core for improved heat rejection.

A magnetic M12 x 1.5 drain plug is included to capture metallic debris circulating through the cooling system, and the package also includes three zip-tie tree clips. The MMRAD-T1-19 is intended for Silverado 1500 and Sierra 1500 V8 applications and is specifically excluded from V6, 2.7L Turbo I4, and 3.0L Duramax I6 models.
