Water pump bolt

Postby adman » Thu Mar 16, 2017 2:29 pm

Hi,

I managed to snap the head off one of the long bolts. Does anyone know the size of the thread so I can buy a replacement? Several places sell a pack of 4 but I can't find the specs of the bolts themselves to replace just the broken one.

Thanks in advance.

Thanks Woody, but do you know what size the bolt is? I'm gussing it's something like 5/16ths as it's close in size to an 8mm bolt. And approx 2" long for a long bolt.

Great, thanks. Got one off ebay for a lot cheaper than having to replace all 4!
