Parts for your 2009 Honda Cr-v-Water pump

2009 Honda CR‑V water pump: what it does and when to sort it

Yes, the 2009 Honda CR‑V absolutely uses a conventional, engine‑driven water pump. Technical references including the Honda CR‑V 2007–2011 Service Manual (Cooling System – Water Pump R&I), Honda’s Electronic Parts Catalogue (commonly listing water pump assembly P/N 19200‑R40‑A01 for the K24 engine), and aftermarket catalogues from Aisin and Gates all specify a mechanical water pump for this model. It’s driven by the accessory (serpentine) belt, while the engine itself uses a timing chain.

On the 2.4‑litre K‑series engine, the water pump’s job is to circulate coolant through the block, head, radiator and heater core so temperatures stay steady, even on a blazing Aussie or Kiwi summer day. When it’s healthy, owners won’t think twice about it — the temp gauge sits rock‑solid, the cabin heater works as it should, and the engine’s protected from hot spots that can cause head gasket dramas.

Servicing is mostly about prevention. Honda’s blue Type 2 long‑life coolant (or an equivalent silicate‑free, pre‑mixed coolant meeting Honda specs) should be refreshed per the owner’s manual schedule, and the cooling system bled properly after any work. While Honda doesn’t set a fixed replacement interval for the pump on this chain‑driven engine, many workshops will recommend replacing it on condition — or proactively around high kilometres — especially if the front of the engine is already apart for other jobs like a drive belt and tensioner.

• Look for pink/blue crust or fresh coolant at the pump weep hole or around the housing.
• Listen for a growly or squealy bearing, and note any wobble at the pulley.
• Watch for creeping temps, low coolant, or a sweet coolant smell after parking.
• Check the accessory belt condition and tension
