VG1500060051 Water Pump WD615.87

VG1500060051 is tailored for SINOTRUK HOWO 375/420 trucks and engineering vehicles, exclusively for Weichai WD615.87 engine. As a key cooling component, it cycles coolant between the engine water jacket and radiator, removing heat from heavy-load work to keep the engine at 82℃~92℃. Built for the WD615.87's tough conditions, it seals reliably, resists wear and high temps, preventing water leakage, bearing seizing, impeller corrosion and low flow-avoiding engine overheating and cylinder damage for steady long-term operation.

①Applicable Vehicles: HOWO 375/420 trucks and large dumpers/mixers with Weichai WD615.87 engine.

②Adaptable System: Fits the WD615.87's original cooling system (radiator, water pipe, thermostat, fan) without interface/bolt hole/inlet-outlet modifications.

③OE Reference Number: VG1500060051

④Interchangeability: Matches original size, mounting specs, water flow and sealing-direct replacement, no secondary debugging or machining.

⑤Value-added Service: Our technicians confirm fit via your vehicle/engine model and provide simple pre-installation guidance.

Core Materials

The pump body uses high-quality ductile iron-tougher, more impact-resistant and anti-corrosive than ordinary cast iron, handling WD615.87's high temp/pressure without cracking or warping. The high-chromium stainless steel impeller resists wear and coolant erosion, maintaining steady flow and long service life. Fluorine rubber integrated mechanical seal prevents leakage even in extreme conditions.

Surface Treatment

The pump body has electrophoretic anti-rust coating-better adhesion and corrosion resistance than regular spray paint, protecting against coolant, rain and dust. The polished, anti-corroded impeller reduces flow resistance, boosts efficiency and extends service life.

Production Craftsmanship

Our integrated production process includes precision casting, CNC machining, bearing press-fitting, mechanical seal assembly, high-pressure leak test and dynamic balance test. Precision casting ensures no internal pump body defects; CNC machining guarantees accurate dimensions for perfect WD615.87 fit. Every pump passes leak and balance tests before delivery for no leakage and stable operation.

• Quality Grade: OE-matching, meeting HOWO technical requirements and national heavy-duty engine cooling standards. Passed 2,500-hour high-temp durability and 120,000-time high-pressure leak tests, with reliable real-world performance.
• Inspection Items: Strict checks on dimensional accuracy, high-pressure leakage, water flow, bearing smoothness, surface treatment, high-temp resistance and dynamic balance-unqualified products never leave the factory.
• Quality System: IATF16949 and ISO9001 certified, with full-process control from raw materials to delivery for consistent quality.
• Batch Tracking: Each pump has laser-engraved OE number, batch number and production date. All records are kept over 3 years for full traceability.

• Average Service Life: ≥5.5 years (550,000km), matching WD615.87-equipped HOWO vehicles, cutting replacement and maintenance costs.
• Performance Advantages: Strong sealing (no leakage), large flow, fast heat dissipation, wear/corrosion resistance, low noise, smooth operation and high-temp endurance for extreme conditions.
• Harsh Environment Adaptability: Works stably at -45℃~130℃, fitting alpine, high-temp, humid and dusty sites. Adapts to all coolants, resisting corrosion.

Common Fault Optimization

We optimized materials, structure, process and seals to fix original pump faults: seal aging leakage, bearing seizing, impeller wear, low flow and abnormal noise. This avoids engine overheating, cylinder damage and power loss, reducing maintenance frequency and costs.

Maintenance & Replacement Value

Easy to disassemble/assemble-maintenance teams can replace it on-site with common tools, saving time. Fully compatible with WD615.87's cooling system, no extra debugging. Stable performance cuts vehicle downtime and operating costs.

Packaging Configuration

Shockproof, anti-collision packaging: inner EVA foam, middle plastic cover, outer reinforced carton. The pump is bracket-fixed to avoid transport damage. Inlet/outlet are sealed; matching gaskets, bolts and instructions are independently packaged.

Marking Specifications

Outer Carton: Printed with OE number, product name, vehicle/engine model, quantity, batch number, weight and handling signs. Export orders include multilingual instructions and qualification certificates.

Product Marking: Laser-engraved OE number, batch number, quality grade and WD615.87 fit-wear-resistant and easy to identify.

Customization Service: Neutral packaging and LOGO customization available. Carton printing, language and size adjustable to market needs.

①Inventory Status: Ample VG1500060051 stock, covering all applicable models. Urgent orders get immediate spot delivery for quick maintenance.

Q1: Is VG1500060051 compatible with all HOWO vehicles?

A1: No, only those with Weichai WD615.87 engine. Provide your vehicle/engine model for accurate fit.

Q2: What to note during installation?

A2: Drain coolant, remove old pump and clean mounting surface; replace gasket, install pump and fasten bolts to torque; connect pipes, add coolant, exhaust air, then check for leakage.

Q3: Custom packaging/docs for foreign trade?

A3: Yes-neutral/LOGO packaging, multilingual instructions and full export docs (invoice, packing list, etc.).

Q4: Leakage during warranty?

A4: Send fault photos, batch number and vehicle/engine model. We send a new pump and cover all freight.

Installation Requirements

Disconnect power, drain coolant; remove water pipes, fan and belt; clean mounting surfaces; replace gasket, install pump and fasten bolts evenly; connect components, add coolant, exhaust air, start engine and check for leakage/abnormal noise.

Regular Inspection

Check for leakage, abnormal noise and loose bolts every 25,000km; inspect bearing smoothness and impeller wear; check coolant level/quality and replace per maintenance cycle.

Storage Requirements

Store in a dry, ventilated, dust-free warehouse away from high temps, humidity and corrosives; place horizontally; seal inlet/outlet. Unopened shelf life: 12 months; apply anti-rust oil after opening.

Replacement Tips

Replace immediately if there's leakage, overheating, abnormal noise, low flow or poor heat dissipation. Replace gasket and accessories together; add coolant and exhaust air after replacement.
