how do you change a heater core on a 1995 Buick roadmaster?

You need a good manual. helminc.com sells the factory GM service manual set over the internet. The heater core is difficult to change in this model. You have to remove a lot of the dash to get at all the screws that hold the cover in place. After that, it's a cinch. Basically, there are seven screws in the cover that is located under the dash, on the passenger's side. All have to be removed. If you can find them all without removing the dash, great. If not, there are several panels that have to come off to get to the screws. Once the screws are off, the core is exposed. There are two small screws securing it to the firewall. After removing the hoses from the engine-compartment side of the firewall, then you can pull the core out of the housing and replace it with a part available from the major "big-box" stores for approx. $50 or so. Be sure to bleed the air out of the system when adding back the spilled coolant. oh, and BTW, when removing the core itself, it is advisable to have a large towel spread under the core so that the coolant that will inevitably spill from the core won't soak into the carpet. Good luck, and allow lots of time to do this, as well as some extra "cuss" time for the stubborn bolts and hoses.
