S1 RST ZVH Coolant hose Query - Where do they Go?
I recently bought a set of hoses to replace my coolant hoses which is pretty much this one:
However, all of the ancillary hoses on my car have been made from straight pipes, meaning that I am a little oblivious to whether the car's hose layout is correct.
For the record I am fairly certain that I have narrowed down a certain bunch of hoses:
-A long bendy hose going from the thermostat housing to the heater matrix (does this connect to the top or bottom port of the matrix or does this not matter?).
-A bypass hose going from the water pump to the rear O/S of the engine where a T(ish) Piece is present.
- An S bend hose going from the T piece to the Heater matrix.
-A short bit of hose going from the T piece to a small junction near the auxillary air valve.
However I am at a loss to what hose goes from the aux valve junction to the bottom of the inlet manifold ; previously a hose was made to be U-shaped here. The one hose that can do this job is also potentially a hose from the header tank to the radiator. This hose however is a so so fitment at the header tank, possibly as a result of the tank being an aftermarket item.
Here is how things stand with the car at the moment. The new long heater hose is visible.
Another heater hose shot, and a T-Piece shot:
The hoses left over. Where do they go?:
Which hose goes from this metal junction where hose is connected to one part of it?:
To here at the bottom of the inlet manifold?
Finally, have the hoses been plumbed in correctly or is there something missing from the setup?
Any help would be appreciated
. If things need to be made clearer feel free to ask for a clearer explanation, the above is possibly a little convoluted!

I think I have figured this out.
The extra hoses and the strange angles etc. for the ancillary coolant hose inlets are due to the CVH originally coming with an oil cooler. Being a ZVH this is no longer the case. What I plan to do is to leave things connected as they are but to take a pipe from the pipe union by the auxillary air valve to the sandwich plate on the bottom of the inlet manifold.
How does that sound? If anyone has pictures of their setup on an MFI that would be great.

Well, I am surprised no one could answer the above with a ZVH...
In the end I realised that I would going to be always left with two hoses spare from the hose kit as a result of the oil heat exchanger not being present on a ZVH. A hose was put it place from the angled bit behind the inlet manifold to the sandwich plate/centre of the inlet manifold so as to complete the cooling circuit, whereas on a stock MFI'd CVH a hose from the angled metal part would then go to the heat exchanger and then back into the inlet manifold/head.
In the future I may look into putting in a heat exchanger or oil cooler, once I can see how hot the oil runs.

I have just build a zvh using s1 pump.
I am having issues on how to pipe this. I have all my hoses set up as s2 exceptfor turbo return which i have put to the pump. ( i have s2 turbo water cooled). And blocked of return at radiator.
Am struggling a bit actually
