  • Bolt size for water pump housing support arm

    Doing my annual maintenance on my 2004 4.3L GXI-E. There is a bracket that supports the inlet and output hoses for the raw water pump, I discovered both bolts were gone and no where to be found. Anyone know what size and thread bolts are used? I know this is a shot in the dark....

    what does the parts breakdown say they are?

    If imperial, 5/16 or 3/8" however they could have switched everything to Metric, which leaves 8mm or 10mm

      I can't find anything on the bolts. Going to buy a handful and carefully see what fits.

        I think they are 3/8. Not sure of the thread size.

            Some seemed to have/use studs and nuts while others used bolts as noted in the 4 options of your engine model seen in the following link..., http://www.volvopentastore.com/Cooli...view_id.775594 ....Edit: Now I see the difference....4.3GXi-E, 4.3OSi-E used bolts while 4.3GXi-EF, 4.3OSi-EF used studs.

            For the bolts image search either Volvo numbers 3853266 or 944429 online as it will help tell you the multiple areas this bolt will fit on many Volvo engines such as front engine mounts, distributor hold down clamps, etc. etc...., https://www.iboats.com/shop/volvo-pe...ew-944429.html
