I flushed/filled my coolant last weekend and had some problems with air in the system causing overheating and no heat. It appears that I've got the system bled and working well, but the last time I was trying to loosen the bleeder valve screw, it completely stripped. Even though it's still tightened, I don't like having the stripped screw in there in case I need to remove it in the future. I bought the replacement part from the dealer, but I can't figure out how to remove the stripped screw. I've tried putting epoxy in the hole and jamming a screwdriver in there, and that was pretty solid, but still didn't loosen the screw. I didn't think I tightened it too much, but apparently I did. Any good ideas to get this removed? Thanks.

 

CAREFULLY drill 2 small holes in the cap. Do not go to far, just til there is a visable hole. Then take a pair of small needlenose pliars and stick the tipe s through the holes, and turn it out. I had to do this on one once before.

 

use a pair of vice grips and break it loose. Then replace the screw. I actually might have an extra bleeder valve assembly in my garage...I should check.

 

yeah id just use some pliars. if you have to you can take the whole plastic deal off which isnt TOO big of a deal either......to get the plug out.

 

You might be able to use a pair of needle nose pliers spinning against the ridges that look like scope cross-hairs.
