🔹Product Overview

This oil cooler core part number 4916621 is a critical cooling component for cumm-ins GTA38, K38, KTA50, QSK38, QSK50 diesel engines. It transfers heat away from circulating engine lubricating oil, keeps oil temperature within safe operating range and prevents oil deterioration under heavy‑load working conditions. Our aftermarket oil cooler core adopts high‑quality stacked metal sheet construction. Every finished unit undergoes strict hydraulic pressure leak test and heat exchange efficiency inspection before delivery. It serves as a direct replacement for maintenance and full engine overhaul, effectively resolving typical failures such as high oil temperature, oil leakage, oil‑water mixing and engine overheating caused by blocked, corroded or cracked original oil cooler core.
