A radiator cap removal tool is a device used to quickly and safely remove the radiator cap of a vehicle. While normally this job is done by hand, sometimes the cap may be stuck and require the extra leverage a radiator cap removal tool can offer.

A radiator cap removal tool can also be used to remove the radiator cap when the cap is still warm. However this should be done very carefully and slowly to release the pressure and make sure the coolant inside does not burst out.
