Coolant level sensing radiator cap
Our new patent pending Radiator Cap now serves 3 different functions, Not only does it have a cool chrome custom top to give you that under the hood look you want, but it also has a magnesium anode to help protect your cooling system from harmful electrolysis. But the coolest feature is it can also sense the coolant level in the radiator without having to be removed! By pushing a button on the Radiator Cap a green LED light will come on indicating a full cooling system. Don't allow you or your loved ones to get burned when checking your radiator.

Coolant inspection and filtering system
Our new Patent Pending coolant Inspection and Filtering System not only allows you to see your vehicles coolant but it also filters out harmful particulates that over time can cause erosion of valuable cooling and engine components. This system will save you from costly repairs and unwanted vehicle down time. Our system is chrome and glass and mounts in the heater core hose. This custom design looks good under any hood and will not distract from the other custom features you may have.

Voltage sponge
Our Voltage Sponge has been in development and testing for 3 year. Rad Cap Products is now able to extract voltage out of your cooling system electronically. The Voltage Sponge is a simple and quick 2 wire connection and works 24/7 removing and burning off harmful voltage that accumulates inside your vehicles cooling system. This voltage over time can cause serious damage and can cause premature failure of cooling system components that are in contact with radiator coolant.
