The 2CV’s boot is spacious but the floor isn’t very flat which makes it a bit impractical to use.
To improve this I’ve added a boot floor. This is a piece of 680mm x 940mm plywood with a notch cut in the back edge to fit round the central support for the back seats and a couple of notches in the front corners to allow it to slide forward through the boot opening thus allowing the back edge to clear the back seat and lift out. There’s also a small block of wood glued and screwed into the middle of the front edge to stop it sliding forward.
With the basic shape fitted I covered it with some bluegrey automotive carpet which provides a nice usable boot floor and the tools and spare wheel live happily under it and out of the way.
To set the ride height on a 2CV you really need two things: a flat and level surface and a 9-22mm tie rod adapter. When changing the chassis we had the former but not the latter and when I subsequently acquired the latter I didn’t have the former. Now I have both…
To make measurement easier I cut two bits of wood to the lengths of the required chassis height as measured between the axle bolts, 195mm at the front and 280mm at the rear (±2.5mm).
To adjust the ride height the tie rods need to be screwed into, or out of, the eyes that connect to the suspension arms via the knife edges. To facilitate this, the tie rods have 9mm flats on them. Whilst you can use a 9mm spanner you need the shock absorbers off in order to address the flat – which is what we did when we were putting it back together after changing the chassis. The right tool for the job is a 22m hex that has a 9mm slot cut in it.
Whilst access to the tie rods is still a bit restricted, with the adapter on the tie rods the 22m spanner can address it in 12 possible ways which, whilst a bit fiddly, is adequate for the job.
Ensure the tire pressures are correct and the car is unladen (except 5l of fuel if you’re being precise). Using the appropriate wooden measuring stick you can see how far off the ride height is. Then, with one side of the car jacked up to take the weight off the suspension and hence the tie rods, you can screw the tie rods in to raise the car or out to lower the car – a rule of thumb is one turn of the tie rods is about 5mm. After making an adjustment, let the car sit back down on the suspension, give it a bounce to settle it, and re-measure. Then, if needed, jack up and re-adjust. As I needed to raise Judith I put a bit of WD40 on the tie rods where they entered the eyes as that made them a bit easier to turn.
When you’re done the wooden sticks should just fit under the chassis between the axle bolts.
The rust proofing – or rather lack thereof – that came from the Citroen factory is well known to 2CV owners and mine was no exception. One of the areas that this manifests is the rear wheel arches as they’re hard to get to with the wings on and they get whatever’s on the road effectively deposited over them by the rear wheels. When we changed the chassis I had a look at them and there was a suspiciously iron oxide tinge to some of the mud brown so I put this job on my list.
With the rear wings off the wheel arches are easy to work on. The first step was a thorough clean of the clart to see what was going on. Mostly the surface was OK and the paint, although not great quality, was still holding. There was still some underseal in evidence but not uniform as evidenced by the areas of surface rust. The main areas were the bump stop mountings and the seat belt reinforcement panels (that had been replaced in 2004).
Treatment for this was a wire brush in a drill to take it back to good metal followed by rust remedy. A top coat of blue hammerite finished it off, this turned out to be much lighter blue than I was anticipating but it’s in an area that doesn’t show, will be covered in underseal and when the rust returns I’ll be able to see if it’s in a new area or the same place which would indicate a deeper problem.
With the rust treated it was time for a decent coat of underseal, not very pleasant stuff to work with but when it’s been warmed up it at least goes on easy enough.
The final part was the leading edges where the wings are affixed. There were a few places where the tin worm had established colonies so these were attacked with the wire brush followed by rust remedy. After some creative masking they were treated to etch primer, primer and two top coats.
With all of that done, this area is now much better protected than when it left the factory, hopefully that should put a crimp in the style of the tin worm which was close to getting established in places.
Of the four variants of 2CV grills the third (number 3) is my favourite – this is the three bar aluminium version (1965-1974). As the bonnet opening was the same shape for grills number 2 to 4 was the same they are interchangeable and the plastic number 4 grill on Judith was broken I picked up reproduction number 3 grill to replace it.
After taking off the old grill, the mesh stone shield that sits behind it and the numberplate I was faced with the old enemy: iron oxide. Round the edges of the bonnet opening the paint had been chipped, the numberplate rubs on the central fold of the bonnet and had gone back through the wafer thin paint, and the mesh was starting to pick up some surface rust. There was also a slight dent in the bonnet at the offside top corner of the opening.
Still, an initial dry fit of the new grill looked good.
After a somewhat inexpert bit of panel beating on the dent, a clean-up of the rust, some rust remedy, etch primer on the bare metal and a keying of the old paint, the bonnet opening was ready for a re-spray.
My rattle can technique needs some work as there were a few runs in the paint (holding the can too close and trying to put too much paint on in one go) and it was quite cold so it dried a bit matt. However, it’s going to be hidden behind the grill and numberplate so a good place to practice.
After the paint had been left for at least a week to cure (another learning moment) and the final touch ups had been done (and left to cure) the grill could be fitted.
The plastic number 4 grill clips in but the number 3 needs bolting in at the top: for this I used countersunk, 16mm, M6, stainless, hex socket bolts with nylock nuts and a broad washer. It has two tabs on the bottom that need bending over to secure it against the lower lip of the opening. The mesh had been coated with the trusty satin black and is held in at the top with the new bolts and at the bottom with the original screws and washers. Finally the grill surround needed a bit of gentle bending to conform properly to the bonnet.
The last thing before re-fitting the numberplate was a strip of anti-rub “helecopter” tape down the centre line fold of the bonnet to protect the paint from rubbing off again.
All that’s missing now is a set of chevrons for the bonnet.
Although someone had painted the heads silver, the original rear wing retaining screws were rusty – to the point one had seized fast and had to be cut out when we took the wings off during the rechassis.
