Where is the water pump located in the new Jetta?

The water pump in the new Jetta is installed on the rear side of the engine. Below are the location of the water pump in the new Jetta and the repair method for water pump leakage: Location of the water pump in the new Jetta: The Jetta's water pump is installed on the rear side of the engine. Automotive engines widely use centrifugal water pumps. Its basic structure consists of the pump housing, connecting plate or pulley, pump shaft and bearings or integrated shaft bearings, pump impeller, and water seal assembly, among other components, making it a major part of the automobile. Repair method for water pump leakage: Disassembling the water pump: First, drain all the coolant from the water pump, remove the V-belt, use special tools to press out the water pump pulley, and then remove the water pump. Water pump disassembly: Use special tools to first remove the water pump bearings, then detach the water pump impeller and seal assembly from the bearings. Replace the sealing ring, new gasket, new V-belt, and new pulley. Assembly: Use special tools to first press the bearings onto the water pump impeller, then press the impeller and seal assembly into their designated positions. Press the water pump bearings into the pulley seat, ensuring the bearing end face is flush with the housing during operation, and the impeller plane is 0.1-0.3mm below the pump housing plane. Inspection: The assembled water pump should have a shaft that rotates smoothly, and the water pump bearings should have no noticeable radial play. Refill with new coolant.
I've seen quite a few water pump issues in automotive repairs. For the new Jetta, the water pump is located at the front right side of the engine, right next to the crankshaft pulley. This position allows it to be easily driven by the belt and is responsible for circulating coolant to prevent engine overheating. I've noticed that many people overlook regular inspections, but in fact, it's prone to wear and leakage, especially under high-temperature operation. If the water pump fails, the engine temperature will rise rapidly, and in severe cases, it can lead to engine failure. I recommend that car owners inspect the cooling system, including the water pump seal and belt tension, every 20,000 kilometers or once a year—don't wait until the dashboard coolant warning light comes on to take action. If you notice any coolant leakage or unusual noises, take it to a professional shop immediately. After all, the water pump design in newer cars is more compact, and DIY attempts can easily damage internal components.
