My 86GT keeps leaking heater cores. Anyone know or has any ideas on why this keeps happening?

Leaking on the passenger carpet or on the ground?

Are you saying the heater core is leaking? Is it coolant or condensation from the A/C (there is a drain for this)? I find it strange that multiple heater cores are leaking. I would have to say it is the hose, or the installation (bent, stressed, punctured) of the core.

I also replaced my heater core within the last year and it's leaking, too. It was a Spectra Premium from NAPA. The cores I was presented from Advance were all too short. The manufacturer's customer service told me to fill the space with insulating foam to hold it in place.

Jack, catch the drip in a cup, feed it to the neighbor's cat. If it survives, it was just condensate.

Lol...... I have 4 cats.....they mean as much as the Fiero to me.
Back to the antifreeze leak.......
I would be looking at my inlet hoses....and tubes. Ck for a loose loose clamp....and making sure that something wasn't damaged when installing. Also check the hvac box drain. I'd should leak on floor unless pluged......thus why there is a drain. It's same as the a/c drain..I have installed many of the spectre heater cores. Never had a issue with one or fitment problem.
I believe Oreily auto parts has a brass core available. Might check into that
Best of luck with
Brian

The problem is... some people will take what is posted literally. In other words, even if you're just kidding about antifreeze not being poisonous, some dolt will believe you.

I just want to make it clear to anyone reading this thread that antifreeze is indeed poisonous.

OK, spare the cats. Bottle it, send it to Patrick. If HE survives, it's condensate.

Now you know why it looks like DexCool. Glad you saw the humor, Patrick. All in fun. But the Red Rock offer still stands, too.

Possibly "stressing" the outlet & inlet tubes during installation? This could crack the brazing. They're kind of fragile you know.

This is the 4th core I have replaced and it is leaking at the header. No leak around the tubes. Before replacing the core one of the water tubes under was leaking due to a hole just under the front heater hose. After replacing the tubes found the core leaking. All this brought my attention as to what is happening to the heater. So got the core replaced today and hopfully all is fixed.

Jack, what brand core did you get? Everything I found was just a little shorter than the Harrison that came out.

Yeah, the replacement heater core I put in my Formula two years ago was a little smaller than the core that came out. It therefore didn't seal along the edges all that well, but I hoped that a bit of air getting past the core unheated wasn't really going to affect the overall warming effect. It didn't, and I'm satisfied with it.

With all your heater cores that have leaked, are you running straight water as a coolant, or are you using the proper 50/50 mix of anti-freeze and water?

Coolant is 50/50 but none of the tablets recommended for a Caddy engine. That has been fixed. GM wanted about $190 for core. Fiero Store asked about $100 and Auto Zone was $46 with life time warrenty. I have tried all 3 and the boxes they came in were all the same with the same markings. Go figure. I have installed the last 3 and have had the same results with the pro-installed. Hopefully this will be the last. By the way my cat (Zig) don't like antifreeze.
