my 67 mustang engine is half apart and i'm waiting on a package to finish project.

been about 10 years so i decided to replace heater hoses.

don't know why ...but my favorite position is not under the dash...

guess i'll just cut hose w/ utility knife and go from there.

suppose i can drop the plenum if i have to.

i have already blown coolant out so it won't drip on my head.

i did figure out an easier way to remove clutch pedal but its been awhile since i messed w/ the heater,

tips...or experiences...anybody?

 

Yeah, whan I removed the heater core case I had to use a hack saw on the little top-hat nuts.

Save everything even the putty around the cover on the firewall until you have everything back in. Make sure your get a good seal between the engine compartment and the passenger compartment to keep the fumes out.

Oh, and my heat vents were made of cheap cardboard that fell apart. Too expensive to replace.

 

you don't want me to wake up bright eyed and bushy tailed

 

Eons ago I had a '67 in which the heater core puked, from what I remember replacing it wasn't so bad. Of course I was young... Now the thought of having to contort under the dash makes me break out in a cold sweat.

I realize this post is of absolutely no help. My wife is watching the Oscars and I'm bored to death.

 

Replacing the hoses is easy, the trick is to detach the heater and lay it on the floor in the car, and loop the new hose through the firewall and attach to the heater. Re-mount the heater, and trim and connect the hoses to the engine.

 

Don't worry that helped..lol

 

i was gonna try w/o dropping plenum. I can just get to the hoses if i hold my tongue just right.

but i think i will most likely drop it like you said...less likely to utter any unnecessary sweet nothings into the air.

thanks ... i can sleep good now...

 

I changed my hoses when I first bought my car 3yrs. ago, they looked original and the thought of taking my wife for a maiden cruise and having the hoses burst spraying 200* water on her ankles didn't sit well with me for some reason.

I layed on my back under the dash with a fresh sharp razor knife and slit the hoses longways from the butt end against the heater core back almost to the firewall, then peeled the hose off the heater core nipple so that I wouldn't break the solder or move the nipples anymore than necessary. Worked well, oh yeah i took the clamps off completely first of course.

I then fed new hoses through the firewall, lubed them with some rubber conditioner (put the new clamps over them loosely) and slid them on the nipples. I think it helped to have someone push the hose from the engine bay to get them over the bump on the nipple.

Agreed. You have to lube the hoses or its a nightmare. I made the epic mistake of removing everything during my teardown and forgetting about the heater hoses until after I installed the plenum. Talk about doing it the hard way for no reason.

I just put a little wd40 on the nipples and it slid right in

 

i lube heater/radiator hoses w/ anti-seize which seems to help years later; hose still sticks. wonder what is the best thing to put on hoses to facilitate removal years later? something like teflon tape would be nice. I may try the white pipe dope this time.

another issue is those wildly popular screw radiator clamps which i don't really like. they can work loose and leak. plus they are kinda ugly.


i like the spring clamps which are not available at parts store. i'm tempted to pick up several spring clamps at the junk yard one day.

Would like a pile of stainless spring clamps for heater/radiator hoses
