DZ95259450100 F3000 Expansion Tank

DZ95259450100 is an exclusive expansion tank for SHACMAN F3000/X3000 series, a key pressure balancing and fluid replenishment component in the engine cooling system. It accommodates coolant expansion from temperature rise, relieves pressure and prevents overflow or component damage. When the engine cools, it auto-replenishes coolant to maintain stable pressure (0.15-0.25MPa). It also bleeds air and enables liquid level observation, separating water vapor to reduce oxidation, corrosion and cavitation. This ensures stable water pump flow, keeps the engine at 85-95℃ optimal temperature, and suits high-intensity conditions like long-haul, mining and engineering operations.

①Applicable Vehicles: SHACMAN F3000, X3000, New M3000, Aolong, etc. Also compatible with SINOTRUK HOWO, SITRAK, STEYR, HOAHAN, GOLDEN PRINCE with same-spec cooling systems.

②Adaptable System: Original engine cooling system, seamlessly connecting to coolant pipelines, water pump inlet and radiator filler pipe, compatible with original liquid level sensor interface.

③OE Reference Number: DZ95259450100

④Interchangeability: Matches original installation dimensions and interfaces, for cab front/rear mounting. Bolt holes align precisely, no bracket modification or pipeline adjustment needed, directly replacing original tank and fitting expansion/overflow pipes.

⑤Value-added Service: Verifies adaptability via VIN/engine model, provides installation guidance, and avoids leakage or pressure issues from mismatching.

Core Materials

Core Materials: Tank body - high-strength modified PP (copolypropylene), impact/high-temp/antifreeze corrosion-resistant, no low-temp brittleness. Tank cap - nitrile rubber gasket for excellent sealing. Liquid level area - high-transparent PP for clear observation. Bracket - Q235 cold-rolled steel, rust-resistant and load-bearing.

Surface Treatment

Surface Treatment: Tank - anti-aging spray, UV-resistant, no yellowing/cracking outdoors. Bracket - electrophoretic rust-proof, 72-hour salt spray resistance. Interface inner wall - polished for less flow resistance and better sealing.

Production Craftsmanship

Production Craftsmanship: High-precision injection molding, no tank defects, uniform strength. Integral injection-molded interfaces avoid welding leakage. In-mold embossed scale lines, clear and wear-resistant. Cold-pressed gasket for uniform sealing. 100% air tightness/water pressure test before delivery, leak-free only.

Production Capacity

Production Capacity: Automatic injection lines, precision molds and testing equipment, monthly output ≥15,000 units. Undertakes bulk foreign/domestic orders, ensures delivery efficiency for distributors and maintenance factories.

①Quality Grade: OE-matching parts, meets SHACMAN standards, bench-tested, interchangeable with originals, suitable for heavy-duty harsh conditions.

②Inspection Items: 0.3MPa water pressure sealing, air tightness, high-low temp cycle, impact resistance, interface tension, scale clarity tests.

③Quality System: IATF16949/ISO9001 certified, full-process control for product consistency.

④Batch Tracking: Laser-marked OE/batch/production date, 3+ years records for full-batch traceability and problem location.

①Average Service Life: ≥3 years (300,000km), matching heavy-duty maintenance cycle.

②Performance Improvement: Modified PP has 60% higher anti-aging, better high-temp resistance. Enhanced nitrile gasket doubles sealing life. Integral interfaces avoid leakage. Transparent scale enables quick coolant check, reducing maintenance time.

③Harsh Environment Adaptability: Resists -40℃ low temp (no brittleness/hardening), 120℃ high temp (stable shape/sealing). Rust-resistant bracket suits desert/coastal areas, no interface blockage/corrosion.
