I need the length, diameter and pitch info on the bolt that secures the top of the air pump down.

Mine fell and magically disappeared, and yes I undid the undertray cover.

Here's a picture of the hole it goes through.

order a new one from malloy

 

Probly an m10 or m12 thread is 1.25 lenght anywhere from 40mm + should work you may have to dye the shoulder off another bolt

 

Thank you very much sir!

Anyone with any more info on it, please speak up before tomorrow morning.

If I have no luck with it the first time, yes, I will probably call Malloy Mazda and get some exact info on it.

 

The bolt is exactly as long as the brackets on the air pump. The mazda bolt is partly threaded - only about an inch.

If you know anyone local with FD parts it shouldn't be hard to get one.

Yeah, I remember that it only had maybe like 6-7 threads at the end of it, I used a 12mm socket to take it off, I'd say the diameter of the bolt itself is M10 and like luckyseven said, 1.25 sounds right.

 

Oh and the only other FD I've seen in Louisiana was in "hondahater"s driveway for a few weeks (was a friend of his). So junkyards are pretty much out of the question down here.

 

I would put in a bigger search party to find that bolt. That's a BIG damn bolt, relatively speaking, and if you actually saw it drop into the engine bay, a good search should turn it up. Get down and dirty in there with a flashlight.

I REALLY hate to just let fasteners go if I lose one. It's VERY possible it's sitting in your radiator fans - first time the fans kick on, that could go through your radiator. Or it could do any number of other bad things to your car. That's far more of a reason to find it, IMHO.

It was me and my girlfriend looking for it for about 2 hours, with 2 flashlights + daylight. I looked underneath, from above, in and around the 1st e-fan housing, pulled the intercooler out to check the 2nd fan, on top of and around the subframe. I really am at a loss about this bolt, I've had a few lost bolt situations (I always work with gloves = butterfingers) just like this, they never ever turn up and it's just one of those mysteries of the car world.

And it's not like it's a tiny rusty old bolt that would blend in with the rest of the bay. This bolt is relatively new, really long and bright silver in color. I just don't understand, there's only so many ways a bolt can fall.
