You always want vacuum lines to take the shortest and most direct route possible.
I had this same problem. There is a vacuum motor in the engine compartment on the firewall, passenger side near the top (close to the hood hinge). Check the white vacuum line that connects with a black rubber elbow to the vacuum motor. The white vacuum line is routed into a bundle of vacuum hoses that route through the firewall into the vent control switches. In my case, this vacuum line had a leak near the point where it enters the bundle. It seemed that the plastic that was exposed to the engine compartment had disintegrated with time and temperature and was very brittle. I was able to fix it with some small diameter silicon hose. If you peel back the plastic jacket that protects the bundle you should be able to find a point where the white plastic vacuum line is still in good condition. Good luck.
pretty straight forward as the rad hoses are much larger in diameter than the heater hoses,one goes at the top of the rad,one at the bottom,the 2 small hose ports don't matter- one goes in,one goes out,the heat doesn't care which way it goes.
Good luck trying to hook up that mess. Can't even distinguish the routing by looking at my Haynes manual. That's why I removed ALL emissions on my '81 3A-C.
If you route your oil lines bases solely on a written description, there's a good chance of a misunderstanding which could lead to serious motor damage, therefore I'm posting the related link to an image: However, if you value your Harley and plan to do your own service & maintenance, you'd be wise to invest in a service manual.
The race route is around an oval that is 2.5 miles long on the Indianapolis Motor Speedway.
"I drove my motor car to the apex of the mountain road and returned by the same route"
There should be a small diagram on a sticker under the hood or in the engine compartment that shows the route of all emission related vacuum lines.
Follow the route of the serpentine belt. It drives the alternator.
Intown road = Rue Highway/Freeway = Auto Route
I have a 1990 Pontiac Transport SE, I have the changed the motor on the driver's window which is power...take off the door panel and you will see the motor...not too difficult of a job...follow the old motor route...
there is no fan belt. the fan is electric-motor powered.
