I'm intrigued as to what this problem is going to turn out to be.

As soon as one of the heater hoses was removed there should be water running out regardless of the direction or types of T, Y etc. When i think of all the strange arrangements of plumbing I've used in the past and had no problems, i can't believe it's just that.

You'd have to have the heater matrix completely block to stop any water, a bit or debris isn't going to do that.
Unless it's been made wrong.

cheers for the reply

Jim
the inlet manifold is new and unblocked along with the hose union
underneath, the matrix is new and so is the pump, the stat housing was
removed and replaced a month ago when i swapped the stat for a warmer
one, i know this flows fine as there is a steady stream from the top
bleed hose back to the reservoir

ive looked more in depth at how ive got the Y piece plumed in now and
also how i had the T plumed in before, and bearing in mind there are 2
flows in and 1 flow out from the Y i have got it so the manifold flows
against the flow from the pump and heater, so ill re - jiggle this and
at the same time when ive got the heater hoses off the matrix ill
check that, although its new im thinking a bit of debris may have made
its way in, but my hopes are pinned on repositioning the Y piece, as
above post, ive got all hoses warm and the elbows i fitted just off
the matrix are transparent, i can see there is no coolant in there at
all but there is further down the hose as they are warm
ill take a look and get back, could be a while though as ive got new
struts going on at the mo

Airlocks aren’t normal on the Mk2 Fiesta/Quantum.
I’ve always just filled them up and run the engine topping up the reservoir if need be until the stat opens.

I can’t think why Jin would have no water at all at the heater, it should flow out under gravity from both pipes.

I’m sure you already checked Jin, or used new parts, but, are you sure that the outlet from the inlet manifold and the outlet from the stat housing are clear ?
They can corrode up.

If it comes up from the alternator yeup that's the electric autochoke wire. I'd keep the coolant pipes round the carb though, bit of warmth might help prevent carb icing/help in cold spells.

Slightly worried about changing my leaky heater matrix now if I risk losing all heat..

Thanks for that, it looks like a really useful website. I can see me spending lots of time (and money!) on that site.

As regards the autochoke, I really don't know / can't remember as it was taken off at least 10 years ago now. I can only assume that it was electrical now that you have pointed out that the hose from the Y piece is required for the inlet manifold. I seem to remember that there is a single wire which has been redundant for many years - I'll bet that was the wire leading to the original choke.

Our local Motor Factor is very friendly and sells lenghts of hose by the metre - I just take a sample of the old one in and they match....

The following web site is useful for ideas -http://www.cbsonline.co.uk/

    On the Carb....
    Did you have a hot water heated Autochoke or was it Electrical?

    The hot water Autochoke had a water inlet tube and an outlet tube.
The old manual conversion kits usually included a short connecting tube (and clips) to allow the autochoke to be bypassed

I had an electricaly heated Autochoke which I converted - the Y piece is still required as I believe it controls the temperature of the "inlet manifold"

      Hi and Happy New Year to one and all.

      I'm after a bit of advice regarding coolant pipework on my 2+2.

I have a problem whereby I cannot seam to get any real heat into the cabin through the heater. (I've had this problem for several years but it's finally got to the top of the list of jobs!)

I have flushed the system out thoroughly and have just replaced the thermostat which opens as it should. I think I have traced the problem to the short hose which is connected to the "Y" Piece and goes over the large metal bar and onto the top of the heater matrix connection on the bulkhead. I think the rubber hose has seen better days and is simply not allowing enough hot water to pass through it into the heater matrix.

I have started looking for a replacement hose but am struggling to find one - Does anybody know where I can get one from / what the correct name for this small pipe is?

Also, as I have a manual choke on my carb, can anyone advise if I still need to retain the hot water supply to the bottom of the carb (Weber VV), or can I simply remove this pipe and therefore get rid of the "Y" piece also?

      Many thanks for your help.

      Cheers,

      Keith
