The present disclosure describes implementations that relate to a pressure testing and refilling a coolant system. In a first embodiment, the present disclosure describes a pressure tester and refilling device that has a valve system and adapters configured to pressurize and pull a vacuum on the system without disconnecting any of the connections. The device includes a plurality of passages that couple to a vehicle coolant inlet, a pressurized air source, an external coolant source, and an exit. Within these passages, the device has several valves that can be controlled.

Pressure testing and refilling devices, systems, and methods

A storage unit, such as, for example, a toolbox or cabinet, having a power strip with power terminals adapted to operably couple to and provide electricity to a connected device. The storage unit further including an interrogation module adapted to interrogate or monitor electric supply information about electricity supplied to the connected devices via the power terminals, a computation module operably coupled to the interrogation module, and adapted to receive electric supply data signals from the interrogation module to determine a status of the connected device by comparing the electric supply data signals and usage characteristics of the connected device, and a communication module adapted to receive status data signals from the computation module and communicate the status data signals to a remote computing device.
