Replacing the cold air intake hose

I just got a hose from Moss to replace a torn original. Got the old one out easily as it fell apart, but it is a bear to get the new one on.

I got it in place by feeding it up from under the car near the exhaust pipes, but slipping it onto the metal sleeves at either end is near impossible. The hose material is paper and aluminum and it is not very forgiving.

While I can access the front part of the intake the rear is near impossible to reach. It makes me think that AH installed these when the engine was out.

Any advise would be appreciated.

I replaced mine while the shroud was off. The engine didn't cause any interference at all. Bob
 
Did mine with the engine out of the car. I was where the engine should have been and it still was not easy. Perhaps some lubricant would allow the air duct to slip over the metal ring a little easier.
 
I've never tried it, and I don't know what made me think of it just now. Maybe remove the vent cover under the dash and install it from the inside. Might be like grabbing a gopher outta his hole, but you never know. At least with my car, taking the fender of requires removing the door first. A lot of work for a hose.
 
Hi Jersey,

Not a easy job but feasible with..........

You have to think round, first of all it very important to have both end of the hose in a correct circle by pushing the end of the hose on a ¨entonnoir¨ funnel to make it perfecly round and one person work from the top the other under the car near the exhaust pipes for rear intake and easily push in place bottom first and easy all around.

Good luck
 
Thanks all...I think I am going to chicken out and cut the hose in the middle and fit the two ends more easily ..then tape the center. Ugh.
 
Jersey: Taking the fender off is a pain. Living with a cobbled together repair is worse. It's too cold up there in New Jersey now anyway, so why not spend a weekend day doing the job right? You won't regret it. One more tip, though. Taking the door off first will dimimish the likelihood of chipping the paint on the fender or the door. Don't ask how I know.
 
Interesting that this topic just came up.
Tomorrow I will be replacing all three of my hoses.

Jersey, the easiest way to put the hose on, and knowing that it is all the way on, is to remove the door first, then the fender. Of course I make is sound easy, but you will need to remove the headlight, turn signal and the stainless beading. All that will take me about 3 hrs. I've done it many times. The hard part is removing the beading. Some of those bolts...ah yes, I remember the fun now.

Once the fender is removed, you'll be able to install the hose in about a 15 minutes. Hint, make the hose as straight as possible, vs. letting it hang in the middle. The air will have an easier time getting to you, so you'll have more of it.

Then put everything back. You can do it in a day.

Let me chime in on Cutlass' taking the door off first thought. Dude, you are so right, don't ask me how I know either!

However, with a lot of patience, persistence, patience, determination, patience and some more patience, you can replace the hose without taking the fender off!

Good luck,
Roger
 
Don't ask me how but I got the heater motor out and changed and the hose back on.

I've been following this thread scratching my head wondering why so much trouble changing out the cold air hoses. I've change both hoses on both my cars with little effort. Then I realized that most people use the paper/wire style that cracks and bends and never regains its shape after installation. I ditched those grappy things years ago. Contact Tom Monaco of Tom's Import Toys, he supplies a poly-butyl rubber air hose that is aircraft quality (boeing) and will never crack, bend, tear, discolor and will last forever. Makes installation a breeze.

I have to agree that one should do the job right. Maybe I will wait until I tear the car down and replace heat and cold hoses at that point in time...its not like I ever need heat...and cool air is a plenty this time of year.


Thanks

Those are the hoses I am replacing, funny you should mention it.
Installation a breeze? Easier, yes. I had a hard time getting the smaller tube from the heater blower though the firewall. That tubes a little bit wider than the stock and the large ridges don't help with letting it slide though either. Then of course is the famous connection of the fresh air to the firewall, that is the topic we are discussing now. Access, location, body position, getting the tube on the little flange, then positioning up the clamp and getting a screwdriver on it, oh I dropped the screwdriver again....don't get me started, lol.

I just can't get used to the look of those hoses. I think the design of the hose, with the wide ridges, is making a resonance sound when the air passes though the tube. I hear the air flow though the left air tube, fresh air. Maybe I'll hear the air flow with the stock, Moss replacement, tubes too? I'll find out soon enough.

Here's a photo for those who may consider getting Tom's hoses.
One photo shows the air hose in place and the replacement Moss hose laying on the engine next to it. The other photo shows them side by side laying on my garage floor.

I agree, Tom's hoses will outlast the car.
Here's another link, right to Tom's hose page.

But, but, but, Dougie, that's cheating! :shocked:
 
If your not cheating, your not trying! (what ever that means)

One tip for those trying to replace the hose on the heater blower side. If you try to take off the fender to gain access, there's a problem. One or two of the fender bolts cannot be accessed with the hose in place. So I found that the only way to get that hose on was to cuss, throw things, drop tools, scrape knuckles and cuss some more. With enough of that, though, the hose can be changed on that side with the fender in place.
