    Changing AC compressor

    I'm replacing the AC compressor on my '87 GN. Been 8 years since I converted to R-134 and replaced the compressor. My CD version of the Service Manual doesn't have an exploded assembly of the mounting brackets/bolting. I've got the alternator tilted up. Does it have to be removed? Does the belt...

    Changing the AC clutch

    My '87 GN AC just stopped working. I tried a hot wire from the battery to the clutch coil connector and got nothing. I assume it is the coil. When I converted the car to R134 5 years ago, I just replaced the entire compressor. Is there a "how to" for changing just the clutch with the compressor...

    power drain

    I installed a tach and boost gage and evidently disturbed some wiring or something. Ran the battery down in one night. There is a pretty good spark when I connect the battery, enough to light a dash bulb. Pulling the Clock fuse stops the drain. I connected to the interiorlight fuse for my...

    Dash light bulbs

    Simple question. Is there any easy way to change instrument panel light bulbs? Can you access them from the front or do you have to get them from under the dash? I'm wanting to go with the brighter bulbs (#168). Thanks in advance

    steering column sleeve

    I just installed my new mini-tach and booster gage. I made a bracket and mounted them to the steering column sleeve. Tight fit, but it works. Then I tried to drive and discovered that the steering column sleeve moves when you shift gears. Obviously, this won't work. Is there a way to dis-connect...

    4000E Manual

    I have an OTC 4000E Pathfinder II scanner and user's manual, but can't locate a "Reference Manual", that is repeatedly referred to in the User's. (I've tried E-Bay for a good while). Does anyone have a copy and would you be willing to scan the chapter titled "Internal Anticipator" and e-mail it...

    Rear axle bearing/shop manual

    I think I have a bad rear axle bearing in my '87GN. Mild roar while driving straight, much louder while steering left, much quieter when steering right. If I remember correctly, this indicates a bad right bearing. I don't have a shop manual and don't want to dive into the repair without one. Is...

    OTC Pathfinder 4000E manual

    I got a good deal on a OTC Pathfinder 4000E scanner. Unfortunately, there were no directions. A friend helped me with basic operation, but I need help with details, especially recording data while driving.I was able to buy a user's manual from the manufacturer, but it keeps refering to a...
