Product Overview

Oil Cooler Part No.3974815 is a vital lubrication‑system cooling component for 6C, 6CT, 6CT8.3L, 6CTA, ISC, QSC, ISL diesel engines used on excavators and heavy‑duty machinery. It completes heat exchange between engine oil and coolant, keeps lubricating oil at proper working temperature, prevents oil high‑temperature deterioration, and protects crankshaft, bearing and other moving components. This replacement oil cooler solves common faults including oil‑coolant mixing, excessive oil temperature, internal blockage and external leakage caused by original cooler core corrosion, fin damage and seal failure. Every oil cooler is strictly tested for pressure resistance and leakage and visually inspected before delivery.
