ZX galvanised?

Post by the_weaver »

Is it true that some panels on the ZX are galvanised? If so, which panels are they?

Thanks

Nope not many, the worst Cit of late ive seen needing welding underneath!

They seem to go were rthe front subframe meets the body at the front..

The shock towers on mine have been welded up rather extensively.

The wing and body panels are zinc primered under the colour. Maybe that is what you are mistaking for Galvanised.

I'm sure I read it somewhere on the internet but I can't find it again. It said vulnerable panels were galvanised.

My ZX has just failed the MOT and needs welding on the front subframe just as predicted by citroenxm.

Is it ok to just slap on some underseal underneath after welding or after cleaning up rust spots or do people normally prime and paint it first then slap on the underseal? Which underseal is the best?

Hi..

the bad news is, if a car fails on welding on a SUBFRAME, then it should NOT BE PASSED by the same MOT man, but if you repair and take it to a different MOT man who has NOT seen the damage then he can pass it, do you actually mean the SUBFRAME or the area by the subframe...

If its the area BY the subframe then this of course can be welded, but an MOT man needs to see the repair BEFORE you cover it over with under seal..

not heard that one before Paul, if i have to do welding from an MOT failiure i just do the required welding underseal it and re/present the car,

but this maybe because the MOT station i use i have been useing for the best part of 30 years, and they know and trust my work,



the XM has several diferent protective coattings all over its body, and i think some panels were galvanised,

I think the welding is near the subframe but not the actual subframe itself.
The car has been welded by the garage and they've passed it on retest. I haven't had a chance to look at the repair yet but I did an inspection before the MOT and I could see some rust on the floor and possibly some on the rails that run along the floor.

I'm always a bit wary of cleaning up rust spots on the floor myself as I never know whether they can be cleaned up with a wire brush and undersealed or whether they should be welded. I would like to clean up the existing rust spots to prevent future trouble but I don't want to cover up anything that the MOT man should be able to see. I suppose that as the car has just passed the MOT then any rust spots that I can find are not serious and can be cleaned up by me.

I've had a few ZXs and they do indeed rust just behind where the front subframe joins. It is however an easy weld to access. I then drill a hole to to prevent the accumulation of water, treat the whole area with Curerust, paint it with Smoothrite or similar, and the spray inside with this stuff which does exactly what it says on the tin. This avoids having to weld it again after a couple of winters. Over the years I've found underseal often promotes corrosion by trapping a film of moisture.
Citroenless at the moment. CX or GS that is my dilemma!

yes ZX's do rust compaired to other citroens of this sort of age,

but i think the reason the outrigers (the box section which comes outwards from the chassis rail to the sill just at the bottom of the bulk head) go west is people use them as a jacking point, (this is a NO NO) this bends the metal and cracks the foctory sealant/mastic coatting which then allows the weather to get at it,

the SAXO suffers the same fait

I think that's what might have happened to mine. I've got a distant memory of a mechanic in a tyre place years ago who I thought had jacked the car up under the floorpan, at the front of the driver's seat. I remember checking the floorpan from underneath, when I got home, expecting to see a big dent, but there was no damage. It was a big trolley jack and I was a fair distance away so I couldn't be sure what he'd done. I wonder if he jacked it under the outrigger. I was looking for a dent but I wasn't looking for cracks in the underseal.

ALL!! 90's cars rust. I've owned a ZX, as have a couple of my friends and family....IMHO a ZX is by no means worse than say a Golf3,polo, Mazda, Toyota etc... and its WAY! better that ANY Vauxhall or Ford of similar vintage.
That being said , I have been amazed how far gone an otherwise "solid" looking zx can be once you get it up and have a peek underneath!... the trick as always is to have it rust treated before it goes on the road.
