The Type-A radiator cap is widely used in 2015 - 2021 Subaru STI and WRX models. It's a key part of an upgraded cooling system. Radium caps are designed to boost cooling efficiency safely by controlling the boiling temperature. A higher radiator pressure raises the coolant boiling point, giving you an extra safety buffer and stopping air pocket cavitation at the water pump. Specs include 1.1 BAR (16.0 psi), a steel cap with an electroplated black finish, premium silicone sealing elements for long - lasting use, and it's made for mini - size (32mm ID) radiator necks only. Note that this item isn't application - specific, so check compatibility before buying.
Using this radiator cap is easy. First, make sure your car's engine is cool. Then, remove the old radiator cap and replace it with this Radium Engineering Type - A cap. When installing, turn it clockwise until it's firmly in place. Remember, this cap is only for mini - size (32mm ID) radiator necks, so double - check your car's radiator neck size before using it. To keep it in good shape, regularly check the cap for any signs of damage, like cracks or worn - out seals. If you notice any issues, replace the cap right away. Also, always verify that the cap is correctly installed to ensure it works effectively and keeps your cooling system running smoothly.
