[C320-list] Leak from broken screw head in water pump

[Dave Hupe]

The broken screw is likely very small (maybe a #4 or#6 machine screw or close metric) and very hard to be able to drill into the shank of the screw and use an easy out.  Is it possible instead to drill straight through the broken screw and either use a tap to create new threads in the body of the pump (for an appropriate sized new machine screw) or could you instead drill straight through and is there room behind to use a screw with a nut?

I had to use it one time on a shift lever for an Edson pedestal where the screw head broke off leaving the shaft inside the threaded hole. May be an option for you…..

Ordered new screw but can’t get the shaft of broken screw out of housing so can’t replace with the new screw. Tried extracting but no luck and thought may just seal it to prevent the leak. Any recommendations
