I had a magic bolt jump from my motor mount to a cylinder when I was rebuilding my engine. Yours seems much better behaved.

 

Hello Roverers!

Remember that "mysterious bolt" that appeared on top the radiator cowl? ...well, just found out where it came from ...luckily!

For a while I've been listening to a high pitch noise, apparently from some front engine bearing, but never got a chance to figure it out, until today, while solving a 0308 issue ...I had to take out the plastic cover that protects the Compressor and one of the expander tubes fell off, so I had to take the radiator cowl out to get it... when I saw a hole in the middle of the Compressor, I jiggled the whole piece and clearly was loose, so I figured the bolt had to be the one to hold in place. Screwed it in ... and it fits like a glove ...so if it fits, it must be guilty! ...got it in, tightened it till the whole things spins, hopefully it will tighten more as it turns, otherwise I don't know how to tighten it even more.

So mystery solved, hopefully the turbine-like noise will go away.

Now back to the other issues! ;-]#

Here some pics!

 

Hi Guys! ...anyone knows the specs of that bolt? just saw this morning that it was missing again, but didn't have the luck of finding it laying around. Help will be very much appreciated!

 

do you have a dealership close? They may have one, could get one, or at the least let you know what size of bolt it is.

 

IDK bolt size, but it's in this kit > A/C Compressor Clutch Kit Repear fits Land Rover Discovery Range Rover Defender

PLEASE....... Loctite that Ba$tard the next time.

 

...thanks CollieRover, but don't have a dealership nearby, although did a good search in the Forum and found the specs for the sucker! M6 x 20mm ;-]#

 

Thanks OverRover, but found the specs for it, is a 6M x 20mm Screw-Flange Hex bolt. A friend that works with home A/C recommended to put a Split-Lock washer as well, so I did, and yes, did put some "medium strength" thread locker on the sucker, and tightened it as hard as I could; no easy way to hold the thing without turning, but I think I tightened it enough. Thankfully truck is inside the garage, so will let it sit overnight and fire it up tomorrow, just for the thread locker to harden as it should. ;-]#

 

nice work!

 

If you have a Fastenal store near you, they would be the best place to get that bolt.

They are my go to hardware store for bolts, nylocks and washers for my Disco.

 

...thanks JUKE179r for the tip, although I did get them from Advance Auto parts (spent no more than $4.30), but already searched for a FASTENAL store around here, and found one within the same distance of the AAP store, so will keep it in mind, thanks! ;-]#
