MONTE CARLO 1988 Monte Carlo SS - Emissions Clamp - Air Manifold Hose
- Thread starter 1988SS
- Start date
It was one of those clamps that had a pinch crimp to hold everything together.
Unfortunately, the original style 1-eared crimp clamps are/were not stocked by GMSPO for over the counter use- EVER. They said to use a worm/screw hose clamp on them. Even in the parts book like that. The pinch clamps were used by the factory because of faster assembly speed. Nothing else. Sure, a worm clamp would work, but pinch pinch pinch and you were done in seconds assembling the trash on the engines.
The correct size 1-ear clamp you need is 1", or what they refer to as a 256 clamp. Original is galvanized steel, but you can get them in stainless.
You'll need a pincher type of pliers to crimp it right, however.
Not sure how many your car has in total, but I would imagine it's the same amount as an Olds, which is 8.
I believe they were originally supplied by Dixon-Keystone, but now ALL the later ones have the newer, dimpled ear for strength improvement.
I can send you a couple of old school galvanized ones if you like. Made by Oetiker, considered the Cadillac of pinch clamps.

Oetiker sells them in two versions, the 10500015 (galvanized steel) and the Stainless Steel versions, 15500015.
Galvanized ones are a tad harder to find. But the stainless ones look good and will continue to look good over time.
I'm redoing all the high temperature A.I.R. hoses with NOS ones, so I've had to go through that merry go round myself. You can get by with heater hoses for A.I.R. hoses, but the originals were designed for the heat effects should a check valve disc fail and burp hot exhaust back through the A.I.R. system. They're heat resistant, but heater hoses aren't and will bubble and burn through faster should a check valve fail.

Sorta. They didn't use the fancy, stepless clamps when they built your car. They used the plain old cheap single band style like I posted earlier. You could use them if you wish, though.
But yeah, on closer inspection, they look like SOMEONE used a stepless style based on those dimples. Although it would be so unlikely it came from the factory I'd bet my lunch money that if it were, it was put there by someone else. There were 8 used on Oldsmobile 307s. 2 per hose. Well, that's IF they remembered to put them on. There's a couple on the 87 that's never had a clamp on them. On the 85 I found a spare right in the middle of the hose that goes to the cat converter. It was just slid on and doing nothing. Quality control was not a priority during the builds, apparently. Nobody can convince me otherwise.
I have black plastic clips on the other ends of the AIR Hoses......pretty sure those are original.
Following upstream a little further there is a crimp clamp....looks like a single band style but on the side looks like what may have caused the dimples.
Yuck....pictures are little embarrassing.....got some detailing to do.

Interesting layout. Hmph. Those are stepless and they do appear to be factory.
Luckily, they got a butt ton of those in different sizes. When you buy them, go by the nominal OD size of the hose. There will be a range that each clamp fits.
