No heating/ tepid
« on: 07 October 2018, 12:04:30 »

Hi
I have searched through the topics and have found lots of help, but I need a bit more if possible.

I have very tepid heating. I have changed the HBV. I have flushed out the heater matrix. Both pipes running into the matrix are now hot but no heat.
I ask, the 2 pipes that run into the heater matrix, can you tell me their routing, where they go to?
The 3 pipes that go into the HBV, where do they go to?
Is it likely the heater matrix is defective? is this the last place to check or change.
I ask pipework routing just in case I put them on the wrong connectors.
The 2 pipes that go into the matrix, what is the item they go into after the matrix.
I cannot find a heater pipe layout plan
Many thanks
Mick

If you have hot water going to the matrix but no heat from it, then it's blocked. Flushing it can help, but won't solve the problem.
I had to do mine each winter, yet it took over 30minutes to get warm. When I fitted a new matrix, the heater got hot in about 1.5miles.
Curiosity made me remove the end cap off the old matrix, and 3/4 of the tubes were so tightly packed with silt that I couldn't poke lock wire down them.
A new matrix costs less than £20, and even though it's horrible job to change following the OOF guide I would do that rather than waste time flushing another.


The two heater pipes than run through the bulkhead after the HBV go directly to and from the matrix; there is nothing else in the circuit.

If you have a few day you not using car empty the water out of the heater and put a full bottle of Coca-Cola in there with 6 caps of string vinegar and leave it in there a few days . And the flush it out a good few times forward and backwards out in to a pan and filter it out to see if it worked at removing the build up.  Did it on a old rad and left it for a week and was completely cleans out  it had been sat in none moving vehicle for 15 years.  Donít worry about it fizzing itís jut bubbles inside the coke and vinegar. See if it works for you did not harm the rad I did it on.

Coke is one of the most corrosive products you can consume ;D

The bubbles aren't the CO2 from the coke, they're the direct result of the chemical reaction occurring as the coke dissolves the radiator and its contents  ::)

It will do the job, but do not leave it more than a couple of days as once it has finished dissolving the scale deposits, it will start on the alloys and eventually the steel :y

Hello,

You can also try to reset climatronic (I have similar problem that my heating was rather bad and it worked).
Reset procedure:
- ignition on
- fan speed low (so you can hear flaps moving)
- press both Auto + Off for ~5sec

Hi, well, changed the matrix. I have hot air when set to cold and tepid when set to cold.
Has anyone a picture of the pipework from the matrix to the? and from the HBV to the?

Basically where ALL the heater pipes run from and too?

When I bought the car someone had run a wire from where the pipes run from a pump? attached to the inner drivers wing across the front to a vacuum valve, and into the relay box.

I also got antifreeze smell and acrid smoke from the bonnet whilst heater was on.
I am at a loss, and if I knew what all the components and where they are situated were would really help.
I cannot find a workshop manual for this car, does one exist?

Thanks again all.

Mick

Haynes do one.  :y

Sounds like you have plumbed the hbv in backwards.

Smoke is never a good sign. But diagnosis over the phone/tinterweb won't work with previous butchery :-\

One for Serek in Huntingdon given your location.

Not the best drawing in the world, but may be of help. Includes pump for winter pack option.
