Technical sources confirm the 2012 Toyota Vitz/Yaris is fitted with a water pump. Toyota’s factory repair manual for the 2011–2017 Yaris/Vitz (Cooling section – Water Pump) details removal and installation procedures, and Toyota’s Electronic Parts Catalogue (EPC, PNC 16100 – Water Pump Assy) lists the pump across common engines used in 2012 models, including 1KR-FE (1.0 L), 1NR-FE (1.33 L) and 1NZ-FE (1.5 L).
