Parts for your 2016 Honda Cr-v-Thermostat housing

2016 Honda CR‑V Thermostat Housing

Based on the Honda CR‑V (2015–2016) Service Manual cooling system section and Honda’s electronic parts catalog for the K24W and R20A engines, the 2016 Honda CR‑V is fitted with a thermostat housed in a dedicated water inlet/thermostat housing assembly on the engine. So yes, a thermostat housing is absolutely relevant to the 2016 Honda CR‑V.

The thermostat housing keeps the thermostat securely positioned at the engine’s coolant entry point, directing flow from the lower radiator hose and helping the engine warm up quickly, then maintain a steady operating temperature. It often carries the coolant temperature sensor and provides the sealing face for the thermostat O‑ring, so it’s a small part with a big job in cooling system reliability.

Owners looking after a 2016 Honda CR‑V should think of the thermostat housing as part of routine cooling-system care rather than a frequent replacement item. There’s no fixed replacement kilometre interval for the housing or thermostat, but inspections are smart every service and especially from around 100,000–160,000 km or 6–10 years. Look for pink/white crust around the join, coolant smell after parking, dampness under the bonnet, or temperature gauge swings. A P0128 code, slow heater performance, or the engine taking ages to reach temperature can also point to a lazy thermostat or a sealing issue at the housing.

• Always replace the thermostat O‑ring when the housing is opened.
• Use Honda Type 2 coolant (blue) and never mix coolants.
• Clean the mating surfaces gently
