Re: 1989 Cacalier Heater Core
Yup, Heater Core, seems like these HCs that GM used SUCK. I have put THREE HCs in my 92. They leak every summer. My 92's is about as easy as it gets to get to. I've heard the horror stories about pulling the whole dash! Well, GM actually did something right, the heat box is directly behind the radio, under the dash in my 92, you have a 89 but maybe it's the same.
There's a smaller piece that has two hoses, two screws, and a snorkel looking piece for the bottom vents. It's easy to take out, and hard to put back in, it fits between the heat switch flap and another piece of plastic or something. After that's off proceed removing the bastard screws off the box. Some are hard to find but you'll know if you missed one, my box was cracked but I finished it off trying to take it off without removing all of them, now I have a new one from a junkard. Once you get the box out there's two metal strips holding the HC in place. Good Luck
