Broken bolt on thermostat housing


Asked by Jan 20, 2014 at 05:51 PM about the 1991 Chevrolet Caprice Wagon RWD

Question type: Maintenance & Repair

Broke bolt for water neck housingFound it online so I ordered 2 few days ago and just got
an email saying that the parts are discontinued. It's for a 1991 chevy caprice wagon with
a 305. Should I just buy a new water neck with bolts? And does anyone know of a part
number so I can find an exact fit

If you got the old one out, you can probably take it to your local hardware store and find the same size for a replacement.

The bolt has a nut that is welded in the middle.


You can also try for the water outlet. Or Tonkinonline or gmpartsdirect, or gmpartsgiant for the bolt(s). The 3 GM sites are excellent sources for parts for older models. HTH. -Jim

Try a local junk yard. 305 and 350 are plentiful and have the same bolts.

Yes it does

You could always get a regular bolt of the same size and pitch and replace the end on the ground wire. Just put the bolt through the end of the ground wire and tighten it down. Or bolt the ground wire to something else close by that's not painted. HTH. -Jim
