Title: Water pump square head nut
Post by: Wookie 66 on September 22, 2020, 06:17:13 AM
Good morning all
Where would I be able to get the square head nut that goes on the water pump it screws in to the water pump body between the top and bottom hoses

Cheers

Otherwise, Bunnings.  I think they still sell cast-iron 1/2" BSP plugs.
(Proviso: I believe the fittings on Holden heads and water pumps were 1/2" NPT (American).  The thread pitch is the same, but the profile's different.  Use Teflon tape, or thread sealant).

Hi guys
Yes I bought the 2 on eBay to find they fit the head but not the water pump
The water pump one is small
One should always measure and not assume

Thanks mcl1959 I would be interested in the smaller size if you have them


Cheers

I’m sure this is the one. Check the dimensions on your pump.
