Question about 1997 Oldsmobile Bravada
Yes, you have to remove the whole dash. Find a friend, a Haynes manual, about 8-10 hours and a lot of patience. I had to do mine twice because the gasket we made caused the first a/m core we installed to fail. Use a paper gasket. If it is leaking antifreeze into the passenger floor, you can bypass the heater core to buy ome time. Cut the incoming and outgoing radiator hoses where they enter the firewall and join them together. You will not have defrost but it will work until you can come up with the cash for replacement. Replacement is just around $1k. If you do it yourself, the part is about $45 and the manual is like $20. Good Luck.

I had a 94 Bravada and when I changed my heater core-I had to remove the dash. It was not a fun job.
