Did a search, didn’t find much, if anything on this issue.

well, its now on my 3rd winter with my 95 bird with no heat. A guy i work with suggested to me today that i use a product called "Stop Leak" to seal up the leak in my heater core. I was googling around the net for the stuff and see mixed reactions, from "it works great, ive run it for 2-3 years since" to "it clogged my system and i had to replace the radiator"

Ive determined awhile ago that its just not worth the expense of 6-700 dollars to get my heater core replaced, especially since the car is barely worth that much. I had given up on ever having heat in my car due to this, but my co-worker suggested this and if it will work, then I would like to try it, but at the same time I don’t want to risk making the car completely un-drivable.

So what are your guys’ opinions on this stop leak stuff? Would you recommend doing it?

You probably clog up the heater core itself. Being disconnected for 3 years who knows what condition its in now.

First off, as Gcline said, if you've bypassed it and let it sit for 3 years, you definitely want to replace it outright. If you left it hooked up, where it still has coolant flowing through it now and then, well I think it's worth a shot.

I had a fairly large heater core leak (hot fluid coming from behind the passenger kick panel), and just for ****s and giggles, I threw a bottle of Bar's Heavy Duty copper stop leak in there. Drove around some twisty roads with the heat on full blast and windows down, as you need to let it do it's thing. Two days later, when I went to start tearing down the dash, I was able to turn the heat on with no fogging. It smelled like pure hot antifreeze, though, and still does when I first turn the heat on. However, I think that's more due to some residual antifreeze being pooled in the plastic casing of the core.

Just be very sure that you're using copper stop leak, not the aluminum kind. If you're going to do it, be prepared to swap out your radiator as well, as bad things really do happen with the stop-leak.

Edit: Also, my coolant level hasn't gone down at all in the three months I've been driving with it like that.

Wel, unfortunally, i dont have the help, especally of someone who knows what they are doing, cause i dont. I was just looking at getting a new cheap 4 banger like an escort or something to replace the bird.

It is also having engine touble, idling is pretty rough sometimes, especally when cold and im pretty much done trying to fix this car. I still dont know how many miles are on it as the odo is stuck on 127k.

Here is a step by step tutorial. You can do it by yourself just plan a full day if you have never done it. Parts will be less than $100 even if you replace the hoses. Although I show how to remove the column you can just drop it down and leave it in the car if you want

If it was bypassed 3 years ago because of a leak, it's probably rotted to $#!t by now. No amount of stop leak will replace the rotted metal. The only fix in this case is a new heater core.

Yea, I wouldn't use Stop Leak. I'd buy a new heater core. I replaced mine a few years ago and it wasn't very difficult. It just was very time consuming.

stop leak is like putting a bandaid on your finger after you cut it off. Will it help? Probably not much if at all.

You don't need help. All you need is basic tools and some time.
