Just use a length of small diameter wire, bend the end a bit and go fishing. Good luck.

Compressed air. Blow it into another coolant port. Not sure if that would work but id figure id try it

Maybe blocking some of the other coolant holes if that is what passage its down. Then shooting air in anther passage way hope it pushes it out. Maybe putting tape on thin screwdriver or other small diameter shaft and put it down hole it fell in, maybe it will grab it. Good luck hope get it out.

Thanks for good options and will try both, i will post if i did it. If it had happend something similar or i am the firts jajaja.

+1 on the above, compressed air. block all other passages as the air will escape the route with the least resistance -only one hole for IN and the Qtip hole OUT.

When I work on tight spots on a helicopter I wire the wrench or screw driver and secure it to my wrist so it doesn't fall inside the flight controls or inside any inaccessible hole. But for you, consider safety wiring your Q-tip so it doesnt fall in again . that would be your corrective training if you worked for me.

Just turn the block upside down.. Itll fall out.

I retract my previous statement.. I didnt read the WHOLE posting.. He said he tried that.

Compressed air should do the trick.

i 2nd that, try to use compressor air. that should do the trick

us a shop vac and suck it out

Compressed air out the way it came in if u can I wouldn't force it deeper just a thought!

If you put the compressed air the way it came in wouldn't it push it in there more. Or get a shop.vac and see if that can pull it out.
