Hi Guys! could someone please give me the step by step proper way to remove a leaking heater core from a 1963 2 door coupe impala without air conditioning?? I've gotten nowhere, different answers and lots of speculation!! as far as I know I have to remove the passenger fender , inner fender, and hood to remove the bolts from around the heater core and blower motor housing ? is this correct? ? I looked under the dash , do I have to remove anything under the dash as well? some people say yes, some say no.Are there any old timers out there or anyone who's actually,physically removed and installed one ? any help would be greatly appreciated. thanks .
