Toyota Sienna V6 3MZ-FE Timing Belt, Water Pump, Seals, & Pulleys Replacement
This video will show you step-by-step on how to replace the timing belt, water pump, idler pulley, tension pulley, camshaft seals and crankshaft seal on a 2005 Toyota Sienna with the 3MZFE engine. I used an OEM water pump made by Aisin, GMB bearings and Bando Timing Belt. This vehicle was overdue for a timing belt replacement by 40,000 miles. The owner stated that the car ran much better after the repair. I assume the old belt stretched causing a few degree misalignment between the crankshaft and camshaft. If you wish to go to a specific repair segment in the video, a breakdown is provided below. A list of parts and specialty tools follows after the video segment:
