Fellas,
I need to remove and replace my heater core. I heard that one could remove and replace the heater core WITHOUT having to remove it from under the (passenger side) dash? Is that correct? In other words, you can remove it from the front? [removing sundry bolts, etc. from the area near the spare tire] I did my search on the Forum but could not find anything? Any ideas?
Cordially,
kevin
Ps. I have the Pontiac sub-speaker near my heater core. Therefore, with all that extra hardware, I fear that I will have to pull out my entire dash to get at it from the inside πŸ˜–

To replace the heater core the heater box must be opened and removed. Its not a difficult job

Thanks Dennis,
I understand it is not that difficult of a job, ihowever, is time consuming, I simply do not want to pull the dash apart to get to the heater core from the inside 🀬, Any additional thoughts?
Cordially,

The core comes out without removing the dash. A/C cars are different.

Kevin, you're under the wrong impression, I think. From underneath the dash, it's not bad at all.

Assuming you have A/C, it must be done from under the dash. Probably won't take an hour start to finish -- especially if you don't have to remove a subwoofer.

It is way more work to replace it via the front trunk (especially if you have AC).

You are correct πŸ˜–,
Fellas,
I was hoping that I would NOT have to take the whole dash apart. 😟. Obviously, this was the origins of my question. Be that as it may, here I go😐........ grab my torx bits, Phillips screw driver and a flat head screwdriver. My Fiero will undergo a mild, ever so slight β€œsurgery” to repair said Heater core.
Cordially

I have done this many times without removing the whole dash takes about 1 hour to r and r a heater core.

I've replaced two Fiero heater cores as well as several other makes/models of cars. The Fiero is the easiest heater core that I've ever replaced.

All my Fieros have A/C and I replaced two heater cores Its just a matter of disconnecting the hoses removing the screws opening the box , unfastening and removing the core downward toward the floor. You do not have to remove the dash and its not an involved process.

have done it many times. the biggest pain is 1 screw that has to be gotten to though the top (Remove speaker cover) and use a long extension. there is no reason it cannot be done is less than an hour.
