Yo guys, How do you remove that crimped-on clamp that holds the MAF to the plastic air cleaner housing? The outlet side is connected with a conventional hose clamp so that is easy. But that inlet side clamp is on there to stay. Is it necessary to use a Dremel to cut it off? And then, what do you use to put it back together?

I'm chasing down a code 33 problem, and may need to replace my MAF. Where can I get a replacement OEM Bosch unit that won't cost me my left nut?

Thanks.

 

if its the one im thinking about, its just like a hose clamp, or it has a handle that releases /locks it

check for that before u get out the dremel

 

My replacement MAF was supplied with a replacement clamp. I "uncrimped" the original and re-used it. Somewhere around here I have a spare, I think.

 

The hose clamp is on the *outlet* side. On the *inlet* side, the clamp is crimped on. No screw or lever. Crimped with a tool. I looked at trying to use a screwdriver to pry open the crimp, but that's gonna take a lot of work, and then how to re-crimp it, since I don't have the tool. I'm thinking maybe slice it open with the Dremel, then use a hose clamp over the top to hold it back together.

OK, and still, where to get a replacement MAF??

 

I can't find mine at the moment, but IIRC, the clamp 'hooked' together at the open end. One side had a tiny hole, and the other side had a tiny post. And when they overlapped, the post 'hooked' through the hole... kind of like a hook-and-loop thing.

It wasn't easy to separate, but I was very persistent and kept sqeezing the ends until I could pop it open. It was one of those times when we wish we had a third hand. Closing it was 'reverse of removal.'

For a replacement MAF, try sponsor TPIParts.net. He has both, new and rebuilt GM/Bosch MAFs.

There's also the Micro-Tech MAF, which is supposed to be better and even flow a little more than the stock MAF. Kragen shows it for $231, new, which is similar in price to a rebuilt Bosch unit. I'm not sure how much your left one is worth, but a new Bosch would probably cost you both!
