Here’s An Update On My Citroën 2CV Because You Have A Right To Know

Cs 2cvupdate3 9 Top

I own a Citroën 2CV. It still feels exciting to type that. I know for a huge chunk of the world’s population, this isn’t a big deal, or even something to get excited about, but for me, a former child who grew up in an America woefully deprived of wonderfully strange French air-cooled cars, it’s still a pretty big deal. And now that the 2CV is actually self-propelled, the whole tone of working on the car has changed, for the better. There’s a vast world of difference in getting a car sorted that you know is capable of running and driving as opposed to one that only drives on a full tank of hope.

There’s still plenty to do on the car, of course. As you may recall from the last update, I was able to drive it from the shop that rebuilt the carburetor, but it was running from a big five-gallon gas can in the front passenger footwell. That still hasn’t been sorted out yet, and, I suspect, probably should be. But I did get some other stuff done.

Vidframe Min Bottom

First, because I know my own self-control is so abysmal and I would be driving it at least a little bit, I needed to take care of some important essentials. Like changing the oil.

Cs 2cvupdate Oilplug

Remember, this car had been sitting in a field for over a decade, and I have no idea how long before that the oil was actually changed, so I think it’s safe to say it was due. The oil drain plug sits in a nice little cutout in the chassis, which has, impressively, a pretty decent “stone guard panel” which looks and feels something like a skidplate. I don’t think I realized the car was so equipped, but I like it.

Cs 2cvupdate Oilfilter

Another interesting thing to note about the 2CV engine is this: it has an oil filter. Now, that’s not a big deal to most people, but as someone who has primarily owned VW Beetles and who used to look at the 2CV engine as a sort of half-Beetle engine (you know, an air-cooled flat-twin instead of an air-cooled flat-four) an actual oil filter is something of a surprise. Beetles just had an oil strainer, a simple little mesh screen doohickey that just trapped the biggest, meatiest chunks out of the oil. That real filter on the 2CV engine is a good reminder of just how different these engines are.

The 2CV engine is simple in the extreme, but not exactly crude. They’re designed to be minimalistic, but the way they’re built and designed is surprisingly sophisticated. Take the head gaskets, for example: there aren’t any. The cylinder barrels and the head don’t need a gasket because the surfaces they share are so carefully and precisely machined that the metal-to-metal contact is good enough. That’s impressive as hell!

I love both engines, of course, but this is just fascinating, I think.

Cs 2cv Update 3 9 1

What else did I do? Oh yeah, I secured the battery tie-down, I put the fan mesh cover back on, oh and I installed those chonky, insulated heater hoses:

Cs 2cvupdate Heaterhoses

Aside from bringing heating and defogging air into the cabin, they also do a lot to help keep the engine noise a bit more insulated, though it’s still a pretty loud car.

Oh! Last time I mentioned the alternator didn’t seem to be charging. Well, I went to my Citroën mentor Til’s house with the car (he gave me the oil filter and some other crucial bits) and he noticed why the alternator wasn’t charging: there’s a broken connection:

Cs 2cvupdate Alternator

I feel pretty silly for having missed something so obvious, but I put a new terminal on that wire and got it hooked back up, and sure enough, that alternator seemed to be working great. Until it started to work, um, too well.

Cs 2cvupdate Voltmeter

I was happy to see the voltage register between 13 and 14 volts, but as I kept driving, the voltage kept climbing. This picture shows it at an eyebrow-raising but not really worrisome 14.9 volts, but it kept going, peaking at 17 volts at one point! That’s too many volts. I think I should check out the voltage regulator next, because I can’t go on like this; it’ll blow everything out if I keep running at 17 volts!

I also ordered some LHM fluid for the brakes; disc-brake-model 2CVs use the same sort of fancy french brake fluid, Liquide Hydraulique Minéral, as the grander Citroën DS uses, and it’s really difficult to find in America. When that gets here I’ll top up the fluid and bleed the brakes.

What else do I need to do? Fuel tank is the big next thing, the passenger side CV boot needs repair, the fenders and filler panels need to go back on, the horn needs better mounting, the headlamp adjustment screws need installed, the tires need replacing, I need to put in the front passenger seat – oh! Did I show you how I fixed the seats? Til gave me some of the OEM rubber bands to replace the many dry-rotted ones, but I didn’t really have enough so I tried something else that actually worked great: ratchet straps:

Cs 2cvupdate Seats

These ratchet straps actually make really good seat springs! I think I may need one more on the driver’s seat, but they make the seats vastly better than what they were like before!

Cs 2cv Update Drive

Mostly I’m just excited about how willing and eager this thing feels to drive. It wants to go, and I don’t blame it. If I had sat for a decade in a field, decaying and getting shot at by ne’er-do-wells, I’d be very excited to be back on the road, too.

I’m not close to being finished yet, but I’m so much further along than before. And that’s very exciting.

Jason, I have to ask what Uncle Adrian thinks of the 2CV?

We know he hates the Beetle – which you also love – but I was wondering his thoughts on the tin snail?

Duct tape is an adequate replacement for the sundry rubberband and rubber diaphragm seat springs too. At the cost of a rather firm ride. BTDT in my Disco I when I fell through the seat one day. Oops.

Machining to perfection to eliminate head gaskets? That’s pretty amazing. Very French too.

I think the head gaskets were scheduled to be added to the design some summer, but then things ran late and suddenly it was time for August break and then they got left behind when work picked up again sometime in October. And then some genius decided that that must have been the design intent from the beginning, and they spread this story about “perfect machining.”

“The cylinder barrels and the head don’t need a gasket …”

Well yes, sure. But also because a possible small leak would just end up in the atmosphere, instead of pressurizing your coolant.

There’s lots of brake mineral oil available in the USA. Shimano and Magura MTB brakes have used mineral oil rather than DOT forever. You could use that.

Of course, the reason I know they’re mostly interchangeable is because of euros running LHM in their MTB brakes because it’s massively cheaper… so maybe not.

Congratulations to you (& Til) for getting the 2CV a-runnin’!!
“The cylinder barrels and the head don’t need a gasket because the surfaces they share are so carefully and precisely machined that the metal-to-metal contact is good enough. That’s impressive as hell!”
Yeah, likewise with air-cooled VW engines having their cases split in half with the metal-to-metal contact being good enough to forgo any gaskets between the case halves. For such economical and bare-bones cars the 2CV and the Beetle indeed do have some remarkably impressive engineering & construction, all right.
As for oil filtration, does the 2CV have an oil bath air cleaner? Some air-cooled VWs did; I know my 1969 VW camper does (I don’t think my family’s 1973 Super Beetle did, though, as it just used a paper element filter IIRC; I also know early air-cooled Porsches used oil-bath air cleaners) and I’m given to understand that VW reckoned that their oil-bath air cleaners were so effective that strainers would be sufficient for the oil.

“[T]he tires need replacing”
Staying tuned for that. Will you be demounting & mounting the tires yourself? What about wheel balancing? And know yet where you’ll get new tires? Asking because my kid & I will be needing new tires which are similar for our project 1954 Panhard Dyna Z. Seems that there are at least two sources for such tires, Coker Tires in Chattanooga, Tennessee, and Longstone Tyres in England (yeah, “Tyres” is kinda a giveaway that the company is British…)

Oh wow, Tire Rack?? Good that you can get tires for the 2CV from there! Does the 2CV use inner tubes?
Just checked and, alas, they do not have the 145R400 (!!) tires for the Panhard Dyna Z (which indeed uses inner tubes) so guess I’ll have to go with either Coker Tires which doesn’t always have that size (yeah, metric, gah, plus it’s ineffably obscure with Michelin being the only manufacturer left still making that particular size) in stock or Longstone Tyres which has to contend with the hassle of dealing with the ongoing tariff situation.

My 2CV (1979) had inner tubes and terrible Firestones from way too long ago. My wheels had the rims for tubeless so I converted when I changed tires. So it depends on the year and what the last person put on the car. IIRC, Jason’s were already tubeless

Yeah, as noted, my system with my 2CV is “it’s a learning project. If I can do it without a shop, I will”. I don’t consider it some sort of badge of honor, I just want the experience. I also… Didn’t trust a tire shop with 3-lug wheels you could bend by looking at them, Uri Gellar-style. Also, I was switching wheels that had been inner-tubed to tubeless so I had a LOT of work to do to clean up the rims for sealing. In the end, with lots of help from our mentor, Til, we dismounted the old, rock-hard Firestones using the air suspension on his DS Break. And then I spent ages doing the wheels and mounting the tires using lube, my Doc Martens, some ratchet straps and an inflator. Took AGES and I reinjured my knee, but all five got mounted.
Jason does not have time for that, and I don’t want him doing more damage to his heart. So I’m hoping a local shop can do it for him.
As for balancing, I’ve felt no issues with mine, so I’m just going with it 🙂

Oh yeah, it’s a great place to visit! Thanks for the reminder (& the recommendation for those who might not know.)
Went there a decade ago; a highlight was when the tour guide showed us the molds they’d just used to make tires for a…GM Futurliner https://en.wikipedia.org/wiki/GM_Futurliner
Based on the timing it seems like it might have been #11 which had just sold at auction for 4 million dollars though the tour guide didn’t give any details other than the fact that the customer who ordered the tires only wanted two tires and was willing to pay something like 10 thousand dollars *per* tire and that Coker had to make the tires in a batch of twelve so they still had ten tires in stock, lol.

There was a replica of a 20s race car there and the owners were “racing” it around the block that Coker Tire occupies. It was a private special event. Also, one of the Coker sons died young, and his car (maybe a Scout? A small four wheel drive not a Jeep) was featured. Some of the cars had QR codes that linked to video of the car’s background and restoration.

Your enthusiasm is palpable. Glad you’re stoked, but it is possible to follow your spirit animal Too closely. Piloting a mobile Molotov cocktail at 60+mph on dry rotted tires, bad brakes, and likely other iffies, case in point. Gonzo did blow himself up on the regular if I recall correctly.

It’s enjoyable to vicariously experience a relic of a time when car purchases, even at the most basic end, were largely about buying something durable that you’d keep for a long time, repairing it as necessary. We’ll likely never see that again, mostly b/c most buyers don’t particularly want it.

The can of PBlaster is the perfect accoutrement for that engine shot.

I was going to point out that while crude in certain regards, the little 2CV isn’t actually crude as much as it is basic. Citroen were certain that gaskets were just another way of saying your machining isn’t very good, and lapped the heads onto the cylinders. That’s a level of detail just not seen, really, anywhere else.

Literally designed to be driven across plowed fields = stone shield. Why? Because there are probably stones in the fields. So: shield.

Rolls Royce also eschewed head gaskets in favor of machined mating surfaces. So this 2CV is practically a Rolls!

Rolls-Royce used that system at all four corners on the Silver Shadow – Mercedes used it on the rear only of the first few generations of E-class wagons. W123-w210, I think. Brilliant stuff, and worth the cost, IMHO. Air is just not as good, though it’s simpler and cheaper.

Nnnnnope.

You have to remove about a 4″ round plate which is held on with 6 nuts. This also removes the screen so it can be washed out. But, as you can imagine, it makes a huge mess.

VW did this to force mechanics to take off the plate and clean out the filter screen. Older engines had an oil plug but mechanics weren’t pulling the screen off, just dropping the oil out.

For dealer service that big hole also helped with cooling the engine to set cold valve lash. Dump the oil, pop the v/c’s off and set up the service fans, wait about 40 min. If a tune up was also due, pull all the spark plugs and cooling was faster.

There’s enough suspension travel that you just about can, with all four wheels still firmly on the ground.

Whoops, sorry – that comment was about the 2CV. The Beetle is more effectively emptied if you turn it completely over.
