Citroen ZX Heater Matrix - M.M
Guys,

A while ago on the old forum we discussed the substantial job of changing a ZX heater matrix.

This is something of a known issue with older ZXs, encouraged by infrequent cooling system maintenance.

I took some photos of the last one I had in and LeeH has kindly uploaded it to his image site.

Have a look at

Quite a lot to take out wasn't there! The hardest part is getting it all back together with no rattles, nothing left over and all the dash bulbs working.

It looks as if the club hammer prominently displayed in the middle of the picture was the principal dismantling tool!

Blimey David! How did you remember where everything went?

Looks like they build the cars by starting with the heater matrix and working outwards!

Car design really has got to a ridiculous stage where you can get at nothing behind the dashboard without that amount of work, and often the engine compartment is no better.
I remember the old Mk1 Cortina which was a dream to work on, you could get your hands up behind the dash and loads of room under the bonnet.
Manufacturers nowdays seem to expect NOTHING to go wrong.
I would gladly buy a well designed car that was not going to cost megabucks in labour to replace a component costing a couple of quid.

You're giving your age away now Brian, the 2nd and one of the best cars i ever had was a Mk1 Cortina, a DIY dream over the seven years in my ownership i fitted a crossflow 1600e 90bhp with a 2000E close ratio box along with new suspension all round, with the 1200 rear axle it was really quick. From that i bought a Mk4 cortina which in comparison was a backward step, never had a Ford since. Happy days.

jud,
Those were the days when you could notice a leaking water pump at work, buy one on the way home and fit it that evening.
Happy days indeed!

Not just me then!

My second car was a Cortina Mk1 (Goodwood Green) which started as a 1200, and then got a tweaked 1500 GT, 5.5 inch rims and modified suspension. On the 1200 axle (4.125 ratio?) it was quick but just ran out of revs. Apart from the wheels and the stance it looked pretty standard, so was fun at the lights.

I later fitted a 3.77 diff from a Lotus Cortina which improved things a bit.

Also had a Mk4, 2.0S. Faster and quieter, but not particularly grippy I recall.

BrianW, you, the consumer demand cheaper cars, with bigger passenger compartments, bigger engines, more electronics, more aerodynamic, more frugal, more comfortable etc. So you have to pay for it at some point.

All very well, but would it not have been nice to take shots along the way, showing locations of hidden screws & clips and other tricky bits such as which plug goes where. A collection of photos like that could build up to be an invaluable resource. One of my pet hates is the way some Haynes manuels tell you to 'remove the trim' but dont tell you where the fixings are and then you end up breaking it getting it off!!!

The photo reminds me of the day I removed the interior and carpets of the MkII Golf to power hose and Vax everything, it came up a treat!!

Dad used to have a standard saying in response to the question "how do you change a waffle vane (or scuttle plate) on a Ford Whatsit?". He'd say "start by removing the back axle".

Plus ca change - plus la meme chose! You didn't have much left before you'd have needed to remove the rear axle on the ZX, by the look of it.

We have the same with a/c evaporators, usually buried in the heater box. Except, Japanese cars, they always have a separate unit behind the glovebox, take about 30 mins to replace.

I find in general that Japanese cars are much better dsigned when it comes to maintenance, though some of it probably stems from being designed for RHD from day one, instead of a LHD design modified for us.

When it comes to manufacturing costs, it make sense for them to have it all in one assembly.

Blimey!

Now I understand why the garage changed all the lightbulbs on the dash when I asked for just the one that was dead to be replaced. I guess while they were in there anyhow.....

With all that wiring hanging around, it makes you realise that there's more and more electrics in cars these days and that a wrench, a pair of ladies tights (mens just don't work) and some grease aren't enough to keep your car on the road these days.
