The Type-A radiator cap by Radium Engineering is a must - have for upgrading your vehicle's cooling system. It's suitable for 2015 - 2021 Subaru STI and 2015 - 2021 Subaru WRX models. This cap is engineered to boost cooling efficiency safely. By managing the boiling temperature, a higher radiator pressure raises the coolant boiling point. This gives you an extra safety margin and stops air pocket cavitation at the water pump. Specs include 1.5 BAR (21.8 psi) pressure rating. It has a steel cap with an electroplated black finish and premium silicone sealing elements for long - lasting durability. Designed only for mini size (32mm ID) radiator necks. Note: This item isn't application - specific, so check compatibility before buying.
Using your Radium Engineering Type - A radiator cap is straightforward. Just remove your old radiator cap and replace it with this one, making sure it's tightly secured. When it comes to compatibility, remember this cap is only for mini - size (32mm ID) radiator necks. So, always double - check if it fits your vehicle before you purchase. Maintenance is easy. Every few months, give the cap a visual inspection. Look for any signs of wear on the silicone sealing elements. If you notice cracks or damage, it's time to replace the cap. Also, keep the cap clean to ensure a proper seal. This will help your cooling system work at its best and keep your engine cool and running smoothly.
