Installed my motorad 180 ...finally... drove it for a day and this evening I check under the hood and the bleed screw for the coolant system had blown off the hose and was sitting on the fan shroud. I tried to screw it back in and the was no thread to screw it to. I know I put it back in cause I blead the system and used a flat head to make sure the screw was tight.

I just don't know how it happened, anyone else have this happen to them.

 

I'd replace the rad cap.

 

Probably cross-threaded it last time you put it in or possibly over-tightened it and stripped the threads.

Doesn't have to be "tight". "snug" is all you need.

 

The weird thing about it is there was nothing to screw it into after it blew out. The threaded part on the hose was gone and all I could do is push the bleeder screw in the hose. Now I could be mistaken and there is nothing on the hose and that it is the hose that is threaded but I thought there was a plastic piece coming out of the hose that has threads for the bleeder screw to screw into....if that makes any sense, lol
Idk probably a new hose will fix it
