    first you must disconnect the negative cable on the battery then remove then remove belt then remove the bolts which could be a 9/16 and or 15mm after you remove bolts remove the wires in back of alt. you my need a 7/16 or 10mm and then the plug if this doesn`t help you try a chilton book for more detalls on tools needed

SOURCE: heater core replacement

OK, Ifound the problem with mine. Dont unplug your air dryer. I checked the 2 hoses coming out from the heater core and still one was hot and the other not hot. The top one comes from the radiator fill tank and the bottom one comes out of the core and goes around to the front and into the water pump. I disconnected both close to the core and could runwater through both directions so upon further examination, I disconnected the hose at the water pump and no water flow. The hose was plugged up with something. Once I cleared it with a hanger and reconnected it I had water flowing through the core and great heat. Hope this is your problem too as it is aneasy fix

SOURCE: replace heater core on 1992

It appears I was incorrect about removing the dash assembly, here are the instructions from a Buick owners club.

Under the passenger dash is an access panel that will allow you to remove the heater core, it really isn't that hard, there are lots of little dash screws and panel screws to remove before you get where you need to be but at least it is roomy. The AC evaporator is located by the heater core. I will give you a tip. I changed mine last year and the heater core that I ordered for my 92 Roadmaster was not correct, when I took my old one out and matched it in a book at the local part store, the heater core for my vehicle was listed as a 96 Caprice???? The car has been in my family since it was purchased new and the heater core had never been changed!!!! Explain that one!Oh yeah, one more tip, if your heater core is leaking, this access panel lowers towards you, if there is nasty sweet smelling water in there it will pour all over you, be careful! Caprice parts are the same as a Roadmaster,so if you ever need anything just look up caprices

SOURCE: How do you take the panel off the rear door of a

On the inside trim, you can remove screws (these screws may be covered by filler pieces or may be visible, or they may require you pry a plastic piece off that covers the screws) that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect any other wiring that may be attached to the door.

Interchangeable car parts

You didn't really specify which parts, but many parts are interchangeable between the 1991-1996 B-body cars (and D-body, the Cadillac Fleetwood). The B-body cars were the Caprice and Roadmaster (Sedan and Wagons), Olds Custom Cruiser (only produced until 1992) and the Impala SS (1994-1996). They all share the same frame (D-body is slightly stretched) and most of the suspension parts are the same, or at least interchangeable. The interiors are different, but most things like seats and door panels would be interchangeable. The B-bodies started out with Chevy 5.0 Liter and 5.7 Liter TBI engines, later the L99 (4.3 Liter) and LT1 (5.7 Liter).

1994 buick roadmaster battery drain pulled fuses all . battery still drawing 11 amps ????

I would check the starter and the alternator, also check the battery cables and connections nd check any circuit with a fuse of more than ten amps for a short to ground. Sounds like you might have some bad diodes in the alternator, though.
