How do you replace the heater core in a 1991 Cadillac fleetwood brougham?

Answer 1

nope i thought i did i pull the thing out to end up realising you get it from the front when u pop the hood on the passenger side you will see the heater fan and all the ac stuff u need to remove the heater fan after that the plastic base were it was mounted comes off all of it u need to remove the plastic grill under the passenger side wiper theres bolts and small screws all around the plastic base/cap thing be carefull with the big screws on the fire wall u might not see them but they are under the black tar sealant crap they put on try scraping it off with a screw driver and u will uncover them then slightly start pulling the plastic base thing slowly cause the glue they put on is old and stiff u might crack it if u just pull it hard it will need to be played around a little bit once its off cause the hood is on the way and it will slowly come out and you will see the heater core right there pull the hoses and remove the bracket on top of it u will see it right away and also theres a clip down at the bottom that the original heater core mounts to it will give u a hard time but it will eventually let go off the core

the new heater core might not fit on the bottom clip like the oem one just drop it in place and push it down and it will just spread the clip and the bracket on top might not fit either at least on mine it didnt i use a zip tie to hold it in place ghetto i know but it work at least i got heat now
