Wonderful kit! Original OEM parts with Aisin water pump, Koyo bearings, and NTK tensioner. Instructions are superb. Follow timing belt installation instructions EXACTLY and it will be a breeze. I made the mistake of putting a GMB water pump on before, and it failed in 70K miles. Never again! Toyota deserves OEM parts! Also, be sure to use only Toyota red antifreeze for corrosion protection.
