Outer sills
Finally got round to getting some chip-resistant paint on the outer sills yesterday.

Over the last few weeks, I had put the pale brownish look to the paint finish as just mud fling from our rural roads, but mud it wasn't . . . it was a beigy colour showing through the black paint on the sills!

Had half a tin of Teknox stone-chip paint left over from a previous job, and decided to give the sills a wipe over with detergent/water to remove any actual mud, and then a wipe with alcohol. Was amazed to find the remains of the black paint started to come off with water :shock:, and then lots more to lift off with a bit of IPA :shock: .

Not sure who had painted these sills, and what with, but a few months of car wash had obviously begun to remove it!

Got most of the rest off, and then noticed what was underneath was good Sable body colour, with a stone-chip coating underneath.

Wonder whether that stone-chip was original factory finish in black, and a subsequent respray (parts of the car have been) put body colour over it? All pics of non-sporty BXs I found seem to have black sills.

Anyway, a couple of coats of the solvent-based Teknox have been applied, so looks a whole lot better. Before painting, I straightened out one or two short sections of the vertical sill seam which had been used (as they do) as a jacking point. A squeeze with a vise supported by a trolley jack got the nice straight line back again.

Verdict on the AC
Must say, after all the pfaff, the AC on the car has turned out to be really rather good.

Apart from the new bits necessary for the conversion/refurb (compressor, dryer and pressure-switch, TX valve, O-rings), the big improvement was cleaning off the evaporator matrix, which was half-choked with dirt/fluff. The air-flow through the system is now massively better, and the blowers can be run at lower speeds. The cooling no longer cuts out if used for prolonged periods (guess the evaporator sensor didn't like what it was seeing), but just...keeps...working. Chuffed.

Also, with the evap now unclogged, ordinary ventilation/heating by ram effect (blowers off) is an option, which is wasn't before.

I'm guessing the system was designed with R134a in mind (Citroen listed the conversion parts), as it seems to work so well on it.

Interesting, I thought all BXs had a flap in the scuttle air intake which opened up between closed and fully open depending on the blower dial position to which it is linked by a cable.
This would mean that even with ram effect very little air comes in when the fans are off. Does yours not have this fitted?

The only flap valves I've seen at the scuttle intake are the two motorised Fresh/Recirc ones.
At moderate speed, fans set to off, there's air flow into the cabin if system set to Fresh.
At motorway speeds, air flow is appreciable.

Have seen the bowden cable leading away from the hot-cold control, but assumed that was just to operate a flap valve in the heater unit itself, rather than an intake control. Could be wrong.

French horns - Jolliffe.jpg
Finally got round to fitting an extra Mixo horn this morning.
Plenty of space in the bumper void for the second one.
The original single (basso) horn always sounded a bit apologetic, so now there's a nice Basso+Alto blare to demand a bit of attention.
You can't beat a nice pair of French horns 8)

I love my apocalyptic air horn in my 2CV, it really draws attention and stops even BMW's before hitting me ;)

My horn stopped working a few years back. It failed the MOT as a result cos I hardly ever use the horn so was unaware of its failure.
Investigation revealed that there were not just one but two horns fitted. They are wired in parallel so that if one fails then at least the other horn will still toot, so both of mine had failed. It was just the wiring., which I repaired, added better support, soldered on new connectors and then had the sound of a two horn chord. It was F sharp.

Temperature gauges
Finally got round to doing something on the list from last year - temperature gauges for the diesel dash:
.

Had been looking for a GTi instrument panel for some time, but not managed to find one, until Eathan came up trumps when he stripped a BX (I had ordered a trim piece from him) only to find a GTi instrument pod languishing in its boot!

Some good fitting instructions on the forum, and another good 'how to' here:
https://citroen.tramontana.co.hu/en/coo ... ture-gauge
including what not to do on a BX with A/C with regard to the sensor wiring.
.

Additional sensor (1337.72; I used a Febi 30767) for the water outlet, in place of one of the blanking plugs) with a single wire back to pin 6 on the 10-way white connector behind the instrument. Pin 7 would allow the oil temperature gauge to operate, if a sensor were added.

That's very good fortune to come across the GTi clocks that way - it's such a reassuring mod to have on a diesel BX. The BX DIY page seems to be the poor relation when (or even if) people go looking for a BX info resource online nowadays, but there's some very useful stuff there.

Chris, does your sump have the hole for an oil temperature sensor (on the front face I think)?
