Prescribing the purpose of closing the mouth of the Legacy Radiators and controlling the internal pressure, which largely remains within sixteen PSI, the Subaru Radiator Cap is indeed of utmost importance when it comes to dictating the performance of the cooling system. Through avoiding the leakage of the coolant and at the same time providing a way of relieding excess pressure, this Radiator Cap increases the safety and durability of the Subaru Legacy. Applying it to various Legacy models, ranging from the first generation in 1989 to the eighth generation shown at the car show, guarantees that each cap must perform certain characteristics that correspond to the specifications of the engines. Defining the appearance of the Radiator Cap, new ideas of cooling were introduced during the period, proving Subaru's direction to progress. Most strikingly, the brand's all-wheel drive system and the boxer engine are prevalent in Legacy models, which means that an efficient Radiator Cap is even more essential on this car. Thus, there is information on how the Subaru Legacy Radiator Cap has certain distinctive characteristics: it holds the pressure readings to the nth degree, as well as having a very sound build to it, which makes it more than capable of standing up to different climates when on the road.
