Abstract:
A method of replacing radiator fluid in an automotive radiator, the method comprising the steps of: providing at least two containers, each of the containers providing a means for sealing against gas leaks from and into the container, a means for fluid conduction, the fluid conduction means integral with a nozzle adapted for sealing a radiator fill pipe nipple; filling a first one of the containers with a fresh radiator fluid; drawing a vacuum on a second one of the containers; establishing suction, using the means for fluid conduction, between an automotive radiator containing a spent radiator fluid, and the second one of the containers; drawing the spent radiator fluid into the second one of the containers using only suction from the second one of the containers, thereby leaving the automotive radiator under vacuum; establishing suction, using the means for fluid conduction, between the radiator and the first one of the containers; and drawing the fresh radiator fluid, from the first one of the containers, into the radiator using only suction from the radiator.
