MAHLE Original Toyota Corolla Coupe Water Pump Inlet Seal

This MAHLE Original water pump inlet seal, part number GS33729, is made from a durable rubber compound designed to withstand engine heat and coolant exposure. It's a small but critical part that seals the water pump inlet, preventing coolant from leaking out around the pump housing. If you're replacing your water pump or notice coolant seeping from the front of your engine, this seal is likely what you need to ensure a leak-free repair.

The rubber material is chosen for its resilience, offering a good balance of flexibility to conform to sealing surfaces and resistance to degradation from engine fluids and temperature cycles. Ensuring a tight seal here is important for maintaining proper cooling system pressure and preventing coolant loss, which can lead to overheating. This seal is designed to fit specific Toyota Corolla, Geo Prizm, Toyota MR2, Toyota Tercel, and Chevrolet Nova models from the 1980s and 1990s, making it a direct replacement for the original part.
