metal water pipe running along by the side of the head

[sujitroy]

I have two metal water pipes. The one on the right is similar to the one used on my Mk1 Stag with a non operational AC unit. The left one must have come from a K reg parts car. I cant on earth figure out the route of the left one. Anyway, I assume i use the right one for my Stag with heater only and I use that rubber pipe. Is this correct?

Sujit,

Did you have an external mechanical water pump?

I do not know about air conditioning so it may be from that but if an external mechanical water pump is used a very similar pipe is used to connect the pump to the heater. That pipe runs on the outside of the RH head and used two metal P clips and nut to piggy back onto to a couple of head studs.

Alan. I have never seen the pipe supported by P clips on the outside of the head. Assuming the standard pump is being used,It should run on the inside, below the cam cover. It comes with a bracket attached at the heater end, which goes on one of the coil mounting bolts, and the pump end is just supported by the hose it is attached to.

Mike this is the second pipe with an external water pump running down the outside of the head, not the "normal" one in the V

The K reg car I parted out didnt have an external water pump. The attachment point on the left hand pipe is broken but in the same location as the right hand pipe. Maybe this pipe was left in the boot.
