Application Details

This Fel-Pro water pump gasket is made for vehicles that require a precise, application-matched seal at the water pump mounting surface. It fits 2006-2019 Toyota Yaris, 2001-2009 Toyota Prius, 2004-2006 Scion xA, 2004-2006 Scion xB, and 2000-2005 Toyota Echo. If you are replacing a leaking water pump gasket on a Toyota Yaris or Toyota Prius, Fel-Pro 35743 provides the sealing profile needed for the job.

This part cross-references MAHLE K31764 for the same application.

What It Helps Fix

• Coolant seepage at the water pump mounting surface
• External coolant leaks around the pump housing
• Loss of sealing integrity after water pump service
• Moisture or residue forming near the pump-to-engine joint
• Repeat repairs caused by an incorrect gasket profile

Installation Notes

Clean both mating surfaces thoroughly before installation and verify the water pump and engine surfaces are free of old gasket material, corrosion, and debris. Match the gasket to the correct engine and mounting pattern for your vehicle, including the five-hole layout and 0.016-inch thickness. For best results, follow the vehicle service procedure and torque specifications for the water pump assembly.
