Peugeot 205 A/C

Hi,

Has anyone tried (successful or not) to transplant the air conditioning out
of one of the later GTI (I think) models and placed it in another
derivative?

Just curious and wondered whether it would be possible....

If anyone has a 205 with a/c I'd be interested in how it is setup - where
the plumbing and controls go etc.

Cheers,

Andy

 

It can be done although requires a bit of DIY to place all the parts - not
sure where it takes 'drive' from - I know if you are retro-fitting the power
steering you have to get a different pully-wheel-thing (sorry brain gone,
can't think of the real name, it's the pully-wheel at the top of the
cambelt!!!) that has a second wheel for the PS belt to run off attached to
the face of it.

Hmmm... you would probably be able to do it if you had an XU-engined
derivate, which I think limits you to either the 1.6 or 1.9 GTi (IIRC)..
basically anything with a 1580 or 1905cc engine.
The standard answer would be to say it'd be easier just to buy another 205
that's already equipped with A/C.

Not sure, but I think it would be plumbed into either the central air vents
or the footwell vents. I'm not 100% sure how all the vents are wired up in
the 205, but I wouldn't be surprised if it uses the central dashboard vents
for the A/C out and the footwell vents as the recirc. It might be indicated
in the owner's manual.

Just curious and wondered whether it would be possible....

Was waiting for that answer )

I've got a Mardi Gras 1.8 TD and not sure if they ever did an option for AC
on that engine. There is already the power steering pump plumbed in
somewhere and the vacuum pump to the side rather than on the end of the
camshaft as on the straight diesel.

Getting tempted to buy a cheap 1.9 GTi that's "spares or repairs" and rob
all the toys and see if I can fit AC and possibly transfer other gizmos.....

Just had a look at the original manual and also Haynes - both show the
heating controls as the same panel except with a little "snowflake" setting
for the AC. I'm guessing there is some different control gubbins for the AC
behind the dash. As to where the heat exchanger unit goes.....? Anyone
know?

Should just be content with my car and not want to fiddle with it... But
that would be boring )

Well, I hadn't considered the diesel models... 1.8 litre, that's 1769cc,
isn't it? If so, then you have an XU-coded engine. So, it'll be quite
similar to the GTi's engine, except for the cylinder head - which, if memory
serves me correctly, doesn't even look *too* different from the petrol
version. The bottom end is virtually identical.
So, I'd say there's a chance you could do it without major modifications -
although I'd want to have a look at where all the A/C stuff is before I got
too carried away, just to see how it all fits in. Possibly, it might just
all bolt on if you have the right mounts and bits.
Say, while you're at it, why not get the bigger 1905cc diesel engine?

Not sure about that. I take it it's not in the Haynes manual?

Yup! Don't be boring, try to break your car!

Chris.

 

Hi Chris,

That's it, XUD7T, or XUD7T/L if after 07/1992. 1769cc you're right, 83*88mm.

Just the look, then : far different indeed, because it is a Diesel. It still
has the 3 11mm bolts on the cam cover, and I guess that's all
The bottom end could be similar, but I'm affraid everything is different, as
a Diesel has more stress than a petrol engine (even if the 88mm bore is
identical to both petrol and Diesel 1.9 versions).
The real common point I guess between XUDs is their inclination : 30° rear

 

Hi,

The belt-driven vacuum pump is there instead of the "common" cam-driven pump
because it has the power steering.

 

Well, I don't have any photographs or anything to go from here - just
memory - but I was sure that they at least *look* very similar from the
outside, which is what I was getting at. It's the same basic block, so
anything that bolts on the bottom end of the petrol version would probably
bolt on the diesel version, providing there isn't something already there in
the way.

I know the cylinder head looks different, but once again, a closer
inspection shows a lot of similarities with the petrol versions, which
clearly identify it as an XU engine, regardless of fuel.

But anyway, like I said, I only have bits of petrol XU engines around here -
I remember once being temporarily fooled by an XUD unit in a breaker's yard
once though. I was looking at it thinking 'what's all this stuff do? Duh!
It's a diesel!'

Hi,

And that is not that sure...

You're right here. Perhaps I got your previous post the wrong way.

LOL !

 

Yeah, I'm just an eternal optimist. Well they *look* the same... hopefully
everything will be alright!

Luckily no one else was there as I tried to figure out how the engine
worked, but I still felt really stupid!

Chris.

 

Hi,

Of course

I have to agree on that point. Sometimes it's so obvious you just don't see
it !

 

Compare for yourselves:

This is a (dirty) XUD7 engine:

This is a (cleaned) XUD7T engine:
http://seppie.webservicez.nl/images/205/jon/jon_0011.jpg
This is a (xud7t converted to a) XUD7TE engine:
http://home.tiscali.nl/jonflorijn/jon/web/Intercooler/images/tdi.jpg
This is a (carb-ed) 1905cc XU engine:
http://www.205gti.com/pics/steve_carbs1.jpg

And why would one bother building a XUD9 engine in a 205? There's not very
much improvement in doing that. The 1769 cc engines are far more reliable
and with turbo and intercooler capable of reaching 110 bhp without major
changes.

Someone here in the Netherlands is also planning to fit a/c on his 205. He
has a 205 Griffe, wich is very packed with extra's already. He said it can
be done. So, he will try.
I'm planning to build powersteering on my 205. I'm not sure to use a
mechanical pump or an electrical... Since the intercooler is placed, there's
not much room for a mechanical pump though...

Hi Jon,

I've got one.

My brother's got one.

Your engine, isn't it ? Well, I've also seen one - Mk1 405s.

We've all seen this one at least once

They may all look pretty similar at first sight, but indeed are pretty
different (esp. between XUs and XUDs, of course), but both have specific
noises - just with my ear I know if it's a Peugeot, and more specifically if
it's a XU, a XUD, a TU or a XD engine.

Well, both 1769 and 1905 versions of the XUD are very reliable.
Some 205s were sold with the XUD9 for export. I've heard of Spain (not sure
about this), but what I'm certain is about German 205Ds. They had the XUD9
in its catalyzed version (just a passive catalyzer, with an EGR valve, nor
electronics nor lambda sensor AFAIK). Improvement is about 3-5HP according
to official (Pug's) specs, which may let run the car at about 160-165KPH.
Too much work for a tiny difference, I have to agree.

With turbo, 78HP, turbo and intercooler it was given for 90HP, to reach the
110HP line you have to tune it a little, perhaps adding a bigger intercooler
and modify the pump's setup.
Could you please give us the mods you need to reach 110BHP (111.5HP) ?

But it possibly requires a lot of work. I thought the Griffe had a/c as
standard. I stand corrected, perhaps wasn't it at export, after all.

Have a look to late, late 205s (called Génération here), perhaps Sacré
Numéro (years 96-98 for Génération, 94-96 for SN), at least the Génération
had an electric pump.

 

Hi G.T

At the local wreckyard there's a 205 Generation diesel. This one has the
XUD9 engine and has an electrical pump for p/s. I'm also wondering how to
reach 110 bhp. I think I'm at 90 now, but i'm not sure. I can adjust the
turbopressure now. But I still have to boost the fuel pressure. Then I'll
probably end up around 100 bhp. A friend of mine who works at the local
Citroënfarm says that the pre-injection-chambers (dunno if that's english)
are more fragile on the 1905 cc engine then on the 1769 cc engine. That's
why I say that the XUD7 is more reliable.
At the moment I'm more busy with the optical tuning than engine tuning. I've
bought 15" gti alloy wheels and those things for on the front and rear wings
and on the doors. I'm giving my Dturbo a gti look. Tonight I fitted the
weels and it looks great. When I've got the right turbopressure gauge, I'll
continue the engine tuning.
But at the moment, it runs great. He's really quick and now I've lowered the
front with 4 cm's or something, it's great in the corners.
I'm eager to know how it runs when I've tuned the fuelpump too...

Greets, Jon.

 

Hi Jon,

AFAIK, all Generation had electric PAS pump.

You should be @90HP as it was the 1.7TD+intercooler standard power.
110 is 22% more, that doesn't seem to be an easy job. Reliability is another
point - the 1.7TD 90HP was known to overheat on 405s.

No clue, but I know what you mean.

Well, I've also heard these pre-chambers are pretty fragile on 1.7Ds
although I've never heard of big problems with them.

I think it isn't necessary. The DTurbo already has a kind of glamour with
its steel wheels and GTi bumpers.

My brother's DTurbo is lowered, too. 30mm, which isn't that bad, with 14" OZ
alloys. Great on curves, too

Perhaps it will just blow the engine :-/
