I still have the manuals. These are original GM manuals consisting of three volumes, each about 6" thick. they fill a bankers box and weigh about 42 lbs.
The manual is specific to the 1987 Buick Regal and all variations. Vol. 1 is chassis, Vol. 2 is electrical and Vol. 3 is the supplement...
Hi all,
it's been a while since I've been here. I have since sold off my GNX. doing some clean up I discovered I still have a complete shop manual for the GNX. If anyone wants it make me a reasonable offer and its yours.
I blew a rad hose at high speed (and a little bit more) one time. It looked like smoke coming out the vents, so I'd say, from direct observation, yes the vents work.
