If you have an older car it may have R12 refrigerant in the air conditioner system. The bigger one goes on the low pressure side of the system and the refrigerant hose will only connect to the low side valve.
Now that the adapter valves are connected, it is time to start the car and put the air conditioner on high. (Do not grab the high pressure line.
What is Automotive Design and Engineering?
; There is a distinct difference between designers and engineers.; The designers are the people that draw the fancy little pictures of what everyone wants a car to be; big wheels, big engines, and radical lines that could never be made on mass scale for consumer consumption (with today’s technology).; The engineers are the people that take that design and make it doable.; In short the designers are Van Gogh and engineers are Leonardo De Vinci.; Meaning that even though what the designers create is beautiful and simply amazing it has no real purpose and can’t be produced or even function on a custom scale.; Engineers make beautiful things that work like so many of Leonardo De Vinci’s inventions.; (Bob Boniface, par.7)
(Car Design Online, Ergonomics, par. 2-3)
In today’s technological world laboring over the clay for weeks is unnecessary.; With today’s technology most of the designing can be done on computers with CAD.; CAD stands for ‘Computer Aided Design.’; These designs done on the computer can give you automatic measurements and can be sent to machines that can recreate them with no manual work.; This technology has even brought clay modeling forward.; Instead of the designers having to carve the entire clay model them selves taking weeks a machine can give the rough out line and then designers can come back and prefect it and change it all they want.; And with the giant leaps with materials they don’t even have to use clay any more to make large three-dimensional models.; After the designers are happy with what the have done in CAD and have made any changes to a clay model and then put that new information into the computer they can make a machine mill down a block of high density foam into a exact replica of the vehicle.; (Car Design Online, Modeling, par. 4)
All of these major tasks have to be completed before a vehicle can even be considered for production.; The way that this paper was worded might have let on that there are only a few people that work on a vehicle at a time but in reality there are full teams of engineers and designers that all have to work one vehicle.; And even with these large teams creating an entirely new vehicle can take years.; And to become one of these few it takes much more then just schooling or talent, it takes determination and patience.; As it does to create one of these works of art.; (Car Body Design, Manufacturing Processes, par. 1-3)
There are some very distinct reasons for this.; One of the biggest ones is the rise in energy costs.; The Japanese cars more often then not are more efficient on gas then the American cars.; Also Japan was the first to really capitalize on the Hybrid cars, leaving America to play catch up with their well-established models.; Another big factor was the sub-par quality that was produced back in the 80’s.; The Japanese cars would last a good ten years if you kept the general maintenance up but American cars were falling apart left and right.; (Webster, Larry, par. 2, 5)
