The idea is to have pipelines running along the chassis of a vehicles. One end of the pipeline is connected to the drain holes of the engine, etc. The other end of the pipeline is attached to valves. The valves and the outlets of the pipelines are located along the perimeter of the vehicles. By doing so, the draining of the vehicle fluids is just a matter of opening the valves with a pan underneath the outlets without going under the vehicle to perform the tasks traditionally.

Also, pressure measurement instruments could be installed for easy monitoring of liquid leak problems such as refrigerant pressure in the AC system. (Copyright and potential patent are reserved)
