Claims
- 1. 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.
- 2. The method of claim 1 further comprising the steps of: providing a control valve joined for fluid conduction between each of the at least two containers and the means for fluid conduction; and selecting first, the second one of the containers using the control valve to enable suction on the automotive radiator, and thereafter selecting second, the first one of the containers using the control valve to enable suction on the first one of the containers.
- 3. The method of claim 1 further comprising the steps of: pressurizing the second one of the containers and establishing connection with the means for fluid conduction between the second one of the containers and a waste repository to enable dispensing of the spent radiator fluid.
- 4. A method of replacing radiator fluid in an automotive radiator, the method comprising the steps of: providing at least four 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; filling a third one of the containers with a radiator flush; drawing a high vacuum on a second and a fourth 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, through the fluid conduction means, using only suction from the second one of the containers, thereby leaving the automotive radiator under a partial vacuum; establishing suction, using the means for fluid conduction, between the automotive radiator and the third one of the containers; drawing the radiator flush into the radiator, through the fluid conduction means, using only suction from the radiator, thereby leaving the third one of the containers at atmospheric pressure; establishing suction, using the means for fluid conduction, between the automotive radiator containing the radiator flush, and the fourth one of the containers; drawing the radiator flush into the fourth one of the containers, through the fluid conduction means, using only suction from the fourth one of the containers, thereby leaving the automotive radiator under a partial vacuum; establishing suction, using the means for fluid conduction, between an automotive radiator, and the first one of the containers; drawing the fresh radiator fluid into the automotive radiator, through the fluid conduction means, using only suction from the radiator, thereby leaving the automotive radiator clean and filled with fresh radiator fluid.
- 5. The method of claim 4 further comprising the steps of: providing a control valve joined for fluid conduction between each of the at least four containers and the means for fluid conduction; and selecting first, the second one of the containers using the control valve to enable suction on the automotive radiator, and thereafter selecting second, the third one of the containers using the control valve to enable suction on the third one of the containers; and thereafter selecting third, the fourth one of the containers using the control valve to enable suction on the radiator; and thereafter selecting fourth, the first one of the containers using the control valve to enable suction on the first one of the containers.
- 6. The method of claim 4 further comprising the steps of: pressurizing the second one of the containers; establishing connection with the means for fluid conduction between the second one of the containers and a waste repository to enable dispensing of the spent radiator fluid; and establishing connection with the means for fluid conduction between the fourth one of the containers and a further waste repository to enable dispensing of the used flush.
