I dont knwo what happened my car got low on coolant in the reserve tank, and it like started to pour steem out of the vents then i noticed anitfreeze was comming in the passesger side what the heck is going on??? I got a 87 z 305 carb..

 

Sounds to me like you need a new heatercore

 

I second what evil cartman said. YOu need a heater core man. Have fun.

 

Definitely heater core.. I had the same problem. Came out in the morning and there's a big puddle of Ecto-cooler in my passenger side foot-well.

I ended up bypassing mine and was gonna fix it before it got cold, but I sold the car instead.

 

damn, how much is a new one or how can i just by pass it im trying to sell the car anyway and antifreeze wont look to good when someone is lookin at it ...

 

guess i shoulda used the search buttom, but looks like i can connect the red-black hoses that go into the firewall looks like a pain to change it...

 

Yes, you can just connect the two hoses and bypass the heater core completely. As far as changing it, I don't know. Haven't looked it up in my manuel yet. If it is like every other car tat I have owned, however, it probably involves dissassembly of the dash.

 

My 84 does not require taking apart the dash, as a matter of fact the guy who sold me my camaro had just changed it.. He said there is only like 4 bolt that hold it in and a person who doesn't know **** about cars could change it in about 20 minutes. Just check it out man. It might be just as easy to replace as to bypass. THey are pretty cheap too, and how good will it look when you sell the car and have to tell them your heater system is bypassed.

 

One of the first repairs I made on my car when I first got it. Not too expensive. I think I paid Pep Boys $100.00 including core, anti freeze and labor. Hell and I really don't drive in thewinter but I like everything working.

 

Just changed mine today, took 30 min to get it out but I had to bend the tubs on the new heater core to make it fit right. It's a PITA.

 

I believe it is only the 91-92 Camaros that require a massive disassembly of the dash to get at the heater core. Don't just bypass it, fix it properly as soon as you can. It is just good policy to keep your car is the best repair possible, according to your pocketbook.

 

i bought a heater core for 29.99 at my local parts store
