Vehicle-fluids exchanger
A fluid exchanger may exchange a fluid (e.g., coolant) in a reservoir (e.g., vehicle radiator) by removing or withdrawing a first fluid (e.g., old, spent, used, etc.) and by introducing a second fluid (e.g., new, clean, etc.). In some examples, the exchanger includes a valve construction that permits easy and safe transitioning from a first mode in which the fluid in the vehicle is run in a loop (e.g., after a cleaner is introduced) to a second mode in which the fluid is exchanged. In some examples, the exchanger includes a restrictor that stops fluid from flowing when the pressure fails to satisfy a threshold (e.g., where the pressure is below a threshold). In some examples, the exchanger includes a safety valve (e.g., ball valve) in the bottom of the new fluid tank, such that when the tank is empty, the valve will close and reduce the likelihood of unintentionally pushing air into the system (e.g., emptying the reservoir).
