High quality aluminum mechanical water pump assembly OE 06H121026CPL is a core cooling system component designed for Volkswagen CC fitted with EA888 Gen2 1.8T and 2.0T turbocharged engines, and it fits other matching VAG series vehicles with the same engine configuration. All mounting hole spacing, coolant inlet and outlet sizes, flange sealing edges and auxiliary accessory installation positions fully meet OEM manufacturing specifications, enabling direct bolt-on replacement without housing polishing or additional sealing glue during engine maintenance and cutting down labor hours for repair shops. The integral pump housing is made of high-strength die-cast aluminum alloy with anti-rust and anti-corrosion surface treatment, equipped with precision cast flow-enhancing impeller and dual-layer fluororubber mechanical sealing components that resist long-term erosion of high-temperature antifreeze and constant vibration under the engine compartment. Aged original water pumps often suffer internal seal aging and tiny coolant leakage, which leads to unstable engine temperature, insufficient heating inside the cabin, continuous coolant consumption and activated cooling system warning lights; delayed replacement may result in severe engine overheating and irreversible damage to cylinder internal components. Each finished water pump assembly undergoes hydraulic leak tightness endurance testing, uninterrupted circulation aging inspection and frequent high-low temperature alternating vibration calibration according to strict OEM quality standards to deliver stable and uniform heat dissipation performance across all batches. We provide one-stop bulk procurement services for global Volkswagen specialized repair garages and cross-border auto spare parts wholesalers, maintaining sufficient spot inventory all year round with flexible minimum order quantity and complete long-term after-sales warranty to meet sustained large-volume purchasing demands of overseas business partners.
