Product Overview
4985547 Water Header Cover (COVER,WATER HEADER) is an important sealing assembly of cooling system for Cummins series diesel engines. Installed on engine water header manifold. It forms a closed cooling circulation channel, keeps cooling liquid flowing normally inside the water header, and prevents coolant leakage.
This water header cover solves common failures such as coolant seepage, insufficient heat dissipation and engine overheating caused by cover deformation, flange surface damage and sealing failure.
Core Product Advantages
High-Strength Cast Integral Structure
High-rigidity casting material, strong pressure resistance, not easy to deform under long-term coolant pressure and engine vibration.
Precision Machined Sealing Flange
Flat mating surface ensures good fit with sealing gasket, effectively avoid coolant leakage under temperature alternating conditions.
Optimized Stress Reinforcement Design
Reinforced rib layout disperses pressure load, reduce cracking risk under cold-hot alternating cycles.
Anti-Corrosion Surface Treatment
Anti-rust coating resists corrosion by coolant, water vapor and engine oil, extend service life in humid under-hood environment.
Precise Mounting Hole Position
Accurately positioned bolt holes, consistent with original assembly benchmark, convenient alignment during installation.
Standard Matching Specification
Dimension 106cm20cm8cm, weight 7KG, perfectly match Cummins engine water header assembly, direct replacement without trimming.
Strict Factory Quality Inspection
All water header covers pass pressure tightness test, flatness inspection and dimensional verification, stable batch quality for engine overhaul and fleet bulk procurement.
