Sounds like the heater core :curses:

 

Yep, you've got a leaking heater core! PITA job to replace!

Good luck..

By the way, don't even think of having a shop do it because they will charge 6+ hours!!!

 

Yepp, heater core all the way; Just got done changing one out on a 99 vert, gotta strip out the dash and all. Makes it easier to take seats out too. Might wanna just bypass the core itself until you get to it

 

Make sure it is not just one of the hoses/hose connection leaking before you attempt to move forward with a fair sized project.

Most times when a heater core is leaking, it does so inside the cabin and not at the engine side of the firewall.

 

bronze is correct. this happened when i put a trickflow intake on my old 91 gt. i thought it was a heater core as well. it was the hose. check the hoses that run off of the manifold to the firewall first.

 

If you SAW it running out of that lower hole, then it is 100% a leaking heater core that must be temporarily bypassed, or replaced.

 

Bypassed it for now. The hoses looked fine ,the only place I coulld find it leaking was out of the firewall drain spot. I guess Ill just go with out my heater . A dash removal is pricey. Hopefully the bypass works and solves the problem. Thanks again for the help . Later

 

its not that hard to replace yourself...just alot of screws and bolts...search the forums there are some good articles on changing them out

 

its easy just time consumeing, have to take out the dash and center console, then if you dont wana take the ac unit out(inside the dash) you have to get a weird lookn screwdriver to get the back screw out of the heater core box.. ita a pain.. make sure you get a "good" heater core not a cheep ass $20 unit, 50resto i hear makes a quallity one, o ya , when u put it in make sure you put a type of sylicone on the edges of the lef heater core.. its kinda funny how it just sets in their with no mounts . i wish they made them like the 86- cars (you just pull that damn heater core out of the glovebox)

I wish my '83 was that easy. That's only on the non-A/C models. Those with A/C still have to pull the dash or cut the heater box.

 

i think i have the same exact thing happening to me, here's a pic of my header right after i got home, you can see the wet hole above it, never figured out what was dripping from it though, i havent been losing any coolant

can you smell it when you come to a stop also? cause i can, and some white smoke comes up

 

Welcome to the club of the green puddle of death called a leaking heater core. Look above the leak you see a roundish rubber piece with a short hose on the firewall. If that is where the leak is coming from your an offical member. Try this link as it has some good pics. Plan on a few hours.
