Was flushing my coolant yesterday and I over loosened the metallic vent screw on the heater line.

Does anyone know the thread/pitch/length of this 8mm bolt? I desperately need to move my car today. The part number is 11537577651, and I'm going to check my local dealers and auto parts stores, but they're not open yet.

Any help is appreciated!

 

Dealer wound up having one in stock. It's got a small vent/bleed hole through it similar to a brake bleeder.

If I find the one I dropped, I'll make a note of it's thread and pitch.

I used some gorilla tape wrapped around the socket and the lip of the bolt/screw. This made it a lot easier to install it. Magnet would work too, but you'd fight a lot (plus I didn't have one with me).
