2001 Toyota Avensis water pump — what it does and when to sort it

Based on technical references including the Toyota Avensis (T22) factory repair manual, the Toyota Electronic Parts Catalogue, and aftermarket catalogues from Aisin (Toyota’s OE pump supplier) and Gates, the 2001 Toyota Avensis is fitted with a mechanical engine water pump across its common petrol (e.g., 1.6, 1.8, 2.0) and diesel (2.0 D-4D) engines.
