Being kinda new to the Fiero world, I did not want to attempt this repair myself. Other vehicles that I have done this on were a huge pain in the ***. After reading this write-up, I thought I would give it a try. Finished the job within an hour. Thanks for the great how-to
Great write up. I just finished this in about an hour from first screw removal to the topping off of coolant. This thread helped make that possible, because I knew what to expect going in. Its the simplest heater core job I have ever done.
Replaced my heater core last night. 88 A/C.. I replaced it with the a "Spectra" aluminum heater core from "Autozone"// I didn't remove the speaker. Upon installing the aftermarket unit I had to remove the original tension bracket that is screwed onto the cover heater core cover.. Heater core cover wouldn't seal with bracket in place. Other than that it was quite a simple R-R..
I am getting ready to do this swap out. PO bypassed the original core. The two houses have been tied together by a plastic sleeve. Which of those hoses go to the top side (heater in) of the core, and which is the return side?
