The Type-A radiator cap by Radium Engineering is a must - have for an upgraded cooling system. It's commonly used in 2015 - 2021 Subaru STI and 2015 - 2021 Subaru WRX models. This cap is engineered to safely boost cooling efficiency by managing the boiling temperature. Higher radiator pressure effectively raises the coolant boiling point, giving you an extra safety margin and preventing air pocket cavitation at the water pump.
Specs:
- Pressure rating: 1.5 BAR (21.8 psi)
- Steel cap with an electroplated black finish for a sleek look
- Features premium silicone sealing elements for long - lasting durability
- Specifically designed for mini size (32mm ID) radiator necks only.
Please note that this item is not application - specific. Always verify compatibility for your vehicle before purchasing.
Using this Radium Engineering radiator cap is easy. First, make sure your engine is cool. Then, carefully remove the old radiator cap. Clean the radiator neck area to ensure a proper seal. Place the new cap on the radiator neck and turn it clockwise until it's snug.
When it comes to maintenance, periodically check the cap for any signs of wear or damage, like cracks in the silicone sealing elements or corrosion on the steel cap. If you notice any issues, replace the cap right away.
Before buying, always double - check that this cap is compatible with your vehicle's radiator. It's only designed for mini size (32mm ID) radiator necks, so using it on an incompatible radiator can lead to cooling system problems.
