The pump features a sealed bearing cartridge that eliminates the need for periodic lubrication, reducing maintenance and extending service life.
This precision-stamped steel cover seals the front of the timing case, protecting the timing chain and providing a mounting surface for the water pump and other accessories. In the Water Pump system, it ensures proper alignment and contains integrated O-ring grooves for leak-free sealing. Its rigid construction reduces vibration and noise transmission, contributing to a quieter cab environment.
These high-strength M12 flange bolts secure the front cover assembly to the engine block. Grade 10.9 with a zinc-nickel coating, they provide exceptional clamping force and corrosion resistance. The 40mm length is specifically matched to the front cover mounting bosses, ensuring proper engagement and even load distribution. The integrated flange eliminates the need for separate washers, simplifying installation.
This high-quality oil seal prevents engine oil from leaking past the front crankshaft journal. Made from FPM rubber with a spring-loaded lip and a PTFE-coated sealing edge, it provides a reliable seal against oil pressure and temperature extremes. In the Water Pump system, it is installed in the front cover and ensures long-term leak-free operation, even under high-speed conditions.
This precision-cut gasket provides a leak-proof seal between the front cover and the engine block. Manufactured from high-temperature resistant cellulose-fiber material with a steel core, it withstands oil and coolant exposure while maintaining dimensional stability. Its precisely located bolt holes and sealing beads ensure a perfect fit, preventing oil and coolant leaks that could compromise the Water Pump system.
These M8 flange bolts are used throughout the Water Pump assembly to secure brackets and auxiliary components. Grade 10.9 with a zinc-nickel coating, they provide reliable clamping force and corrosion resistance. The 25mm length is suitable for light-duty fastening applications, such as attaching the distribution housing or small brackets.
These medium-length M8 flange bolts are used for securing the distribution housing and other medium-load components. Grade 10.9 with a zinc-nickel coating, they provide reliable clamping and corrosion resistance. The 40mm length is ideal for deeper mounting points within the Water Pump system.
This cast aluminum housing distributes coolant to various engine components, including the water pump, heater core, and oil cooler. In the Water Pump system, it incorporates precisely machined ports and sealing surfaces, ensuring efficient coolant flow and minimal pressure drop. Its integrated bypass passage ensures continuous circulation even when the thermostat is closed.
This gasket seals the distribution housing to the engine block. Made from high-temperature fiber material with a metal insert, it withstands coolant and oil exposure while maintaining a leak-proof seal. Its precise cutouts match the housing ports, ensuring unrestricted coolant flow and preventing cross-contamination between oil and coolant passages.
These long M8 flange bolts are used for securing the distribution housing to the engine block. Grade 10.9 with a zinc-nickel coating, they provide high clamping force and corrosion resistance. The 100mm length accommodates deeper mounting points, ensuring a secure and durable attachment of the distribution housing.
This gasket seals the water pump to the engine block or distribution housing. Manufactured from high-temperature resistant cellulose-fiber material, it provides a reliable seal against coolant leakage. Its precise shape matches the water pump mounting flange, ensuring a perfect fit and preventing coolant loss that could lead to overheating.
This precision-machined steel pulley drives the water pump via the engine’s serpentine belt. In the Water Pump system, it features a multi-groove profile that ensures positive belt engagement and minimizes slip. The pulley is dynamically balanced to reduce vibration and noise, and its corrosion-resistant coating ensures long-term durability in the harsh under-hood environment.
These short M8 flange bolts are used for securing the water pump pulley to the pump hub. Grade 8.8 with a zinc-nickel coating, they provide reliable clamping force and corrosion resistance. The 12mm length is specifically matched to the pulley mounting holes, ensuring a secure attachment and proper belt alignment.
These extra-long M8 flange bolts are used for securing the water pump to the engine block through the distribution housing. Grade 10.9 with a zinc-nickel coating, they provide exceptional clamping force and corrosion resistance. The 130mm length accommodates deep mounting points, ensuring a rigid and secure attachment of the water pump assembly.
This sealing washer provides a leak-proof seal for threaded connections in the Water Pump system. Featuring a steel core with an FPM rubber coating, it withstands coolant and oil temperatures up to 150°C. Its 14.7mm inner diameter and 22mm outer diameter ensure a perfect fit with M14 fasteners, preventing coolant leakage and maintaining system integrity.
This screw plug seals a coolant or oil gallery port in the Water Pump system. Featuring a hexagon socket drive and a M14X1.5 thread, it is zinc-plated for corrosion resistance and pre-coated with thread sealant to ensure a leak-free seal. Its compact design allows it to be installed in confined spaces within the engine bay.
This stainless steel pipe carries warm coolant from the water pump to the urea tank heating system, ensuring that the urea solution remains fluid in cold weather. In the Water Pump system, it is routed to avoid heat sources and moving parts, and its flanged ends provide secure connections for leak-free operation.
This specialized tie is used to secure a single wire or small bundle in the Water Pump system. It provides a secure hold without damaging the wire insulation, maintaining a clean and organized wiring layout. Made of UV-stabilized nylon, it resists aging and maintains tension over the life of the vehicle.
The Water Pump is engineered to deliver consistent coolant flow at all engine speeds, ensuring optimal temperature control and preventing overheating. This protects critical engine components from thermal stress and extends engine life.
This Water Pump kit includes all necessary gaskets, seals, fasteners, and auxiliary components, providing everything needed for a full replacement. No additional parts are required, saving time and ensuring compatibility.
All Water Pump components are manufactured from high-quality materials, including aluminum alloys, zinc-nickel coated steel, and high-temperature rubber. This ensures long-term resistance to coolant, oil, and environmental corrosion, providing reliable service over millions of kilometers.
