Maintenance and service 11-11 Cooling system WARNING Never attempt to remove the radiator cap until the engine has been shut off and has cooled down completely. Since the coolant is under pressure, you may suffer serious burns from a spray of boiling hot coolant when the cap is removed. CAUTION . The cooling system has been filled at the factory with a high quality, corrosion-inhibiting, year-around coolant which provides protection against freezing down to −338F (−368C). Subaru engines use aluminum components that require the anti-corrosive and anti-freeze properties of Subaru Genuine Coolant, which is specifically formulated for the Subaru cooling system. Failure to use Subaru Genuine Coolant along with Subaru Cooling System Conditioner at the recommended main- tenance intervals may result in problems, including, but not limited to shortened life of engine components and cooling system clogging, coolant leaks and engine damage from overheating. Problems caused by the failure to use Subaru Genuine Coolant and Subaru Cooling System Conditioner at recommended intervals are not covered under the Subaru Limited Warranty. While there may be other generic products that may provide the required protection, they have not been tested for compatibility with Subaru engines and cooling system components, and therefore not recommended. . Do not splash the engine coolant over painted parts. The alcohol contained in the engine coolant may damage the paint surface. even when the engine coolant temperature gauge exceeds the normal operating range, the cooling fan circuit may be defective. Check the fuse and replace it if necessary. If the fuse is not blown, have the cooling system checked by your SUBARU dealer. If frequent addition of coolant is necessary, there may be a leak in the engine cooling system. It is recommended that the cooling system and connections be checked for leaks, damage, or looseness. & Engine coolant ! Checking the coolant level & Hose and connections Your vehicle employs an electric cooling fan which is thermostatically controlled to operate when the engine coolant reaches a specific temperature. If the radiator cooling fan does not operate Check the coolant level at each fuel stop. 1. Check the coolant level on the outside of the reservoir while the engine is cool. - CONTINUED -
