Description

Keep engine temperatures in the right window with the AISIN Engine Coolant Thermostat (THF006), a front, lower-mounted thermostat assembly that opens and closes to regulate coolant flow through the cooling system. It's a direct-fit replacement for many Subaru models, including the 2020-2023 Subaru Outback [H4-2.4L], 2014-2018 Subaru Forester [H4-2.0L] and 2020-2023 Subaru Legacy [H4-2.4L] — see the "Vehicles it fits" section for the full list of applications and engine codes.

Materials: brass and stainless steel construction.
Start-to-open temperature: 88°C (190.4°F) to help maintain the cooling system's operating range.
Includes a jiggle pin check valve to help vent trapped air during coolant fill.
Gasket/seal included; sealing flange outside diameter 56 mm, flange height 36 mm, bypass flange diameter 28 mm.

OE engineered for exact form, fit and function, this standard-design assembly restricts coolant flow when the engine is cold and opens as temperature climbs. If a thermostat stuck open (slow warm-up) or stuck closed (overheating) is the cause of your cooling trouble, this replaces it. Country of origin: Japan.
