2018 Toyota RAV4 water pump — purpose, care and when to replace

Yes, a water pump is fitted to every 2018 Toyota RAV4, and it’s absolutely relevant to the cooling system. Toyota’s Repair Manual for the 2018 RAV4 (Cooling System section), the Toyota New Car Features (NCF) guide for the 2AR series engines, and Toyota’s Electronic Parts Catalogue all show a dedicated engine coolant pump on both petrol and hybrid models.
