Coolant Leak from interior of car? please help

[savegoodautonfg]

I'm on the way home driving my girlfriend to her house at around 11pm tonight the 17th and she says to me their is yellowish stuff leaking from i guess the ducts or vents under her feet. I pulled over and go out and layed underneath her seat. I felt all the vents and ducts and **** under there and they were wet from coolant. My carpet has some yellowish coolant im guessing on it also. I would think it would be my heater core but my heat was working perfect warm as hell but my windshield would not defog. it was foggy all night. please help..

THanks in advance!!!

Bad heater core.....better block it off for now, until you can replace it.

That sucks. That is a symtom of a leaking heater core. It's a little harder to replace than a hose clamp.

I knew but was hoping you wouldnt say that. well im going to bed now got work in a few hours. but iwas wondering how can i block it off for now? and that also means i cant use the heat right?

yea thats def the heater core, mine screwed up away from my house, cuz the solder joint broke so i yanked off that pipe coming off the heatercore and bent it little more to do a 180 degree turn and just used that to connect the 2 pipes together and worked fine for the whole summer...you just wont have heat...and in my opinion my heater core wasnt hard at all to change

BTW stores sell the correct size pipes to bypass the heater core(they are 2 different sizes)...i no strauss auto has it for sure and im pretty sure advance auto does too

You are going to have to bypass where your hoses connect to the firewall with a new piece of hose.

You know what pisses me off about a leaking heater core is cleaning the coolant out of the carpet. That crap is hard to get out.

simple green, scrub brush, and a wet/dry vacuum. Sounds like all kinds of fun!

I heard non A/C stangs are easier than ones with A/C but I have never changed one is this true. Mine went in the summer so I bypassed it and I think i'll change it this year.

A/C cars are an all day job. Non A/C cars can be done in less than 2 hours.

Yea good luck .. my car was and A/C car if i had to do it again i think i could do it fairly fast now but the first time is a bitch.. I was working by myself and i forget there was something holding me from getting the dash all the way out but i could see the heater core box. So i did what anyone would do .. Cut the back off the box off pulled the heater core out slid the new 1 in and put a crap load of tape over the hole... Cuz u need to get the dash all the way out then get to some pain in the ass screws on the top. GOOD LUCK

I'm really confused about the whole bypassing it? Please someone explain how to do this.

Also can i use my a/c in the summer still if i bypass it?

Go to an auto parts store and buy a heater core bypass hose. I think I paid like $7 for it. It is U-shaped and has different sized opening on each end. Open the hood and on the passenger side firewall you'll see two adjacent hoses attached there. One is the input and the other is the output for the heater core, which is right on the other side. Simply remove the hoses and attach the bypass hose to the fittings opposite the heater core. MAKE SURE that you don't kink the hose. When you change the heater core, have patience-my first time took almost an entire day. I couldn't get the speedo cable off at first.

i have had to replace my ac heater core. it's about as much fun as being drug face down through a women's prison by your testicles. ( don't even ask ) i would set aside a day and get an early start on it. and BE CAREFUL when putting the new one in - they are very easy to damage. once i had the new one installed i sprayed the outer edge with rubberized undercoating since i had a can handy - a little cheap insurance agaginst vibrations etc.

It's really not that hard to change..... When I changed mine it was my first time pulling the dash on a Ford... Took me about three and a half hours total.... I just pulled the whole HVAC unit out of my car a few days ago in less than a hour.

TIP: Take the seats out... It really is alot easier... I didn't do it the first time
