I think it's fine. I dimly recall changing it a decade ago. Recently. I'll check it anyway. I'm thinking of making the nuts that attach the box to the bulkhead captive. It would make refitting a bit easier. If I attach then to the little brackets, that should do the job.

I'll probably not get back to this for a bit, hopefully next week. But I'm reminded by how delightfully simple these vehicles are. Heater box removal requires a couple of bolts and a hose clip. Disassembly is just a dozen screws. Bliss.

Interior sprayed with zg90 zinc rich stuff. The hot weather is great for drying paint.

Neoprene ordered. Spare heater box awaiting second coat of black zinc paint. Replacement matrix awaiting unpacking. I might have a working heater this time next week! Just in time for the summer.

Neoprene, is that the best? Longevity? Water proof? Not a rust sponge? eBay?

Does it look like this?

That's good to know. Thanks Nick. All I need now is some spare time!

Exactly. 40 year old wiring is brittle. G.

Do I have to take the instrument cluster off? Been so long since I've done that, I forget. G.

Is it a later dual circuit with servo type? With the switch in the engine compartment? That switch is very different to fit, the ROM covers it in detail. Basically, if you screw it in too far, the pedal rams the plunger through the contact plate, breaking it. Works once, then intermittently, then not at all.

I'll post up when it arrives. But the bigger problem with mine is in the under dash tray. I suspect it's full of gunk and dead foam. I suppose I should just bite the bullet on that one, but it frightens me slightly. G.

Well, I had a look at mine, and the tdi pump is fine (Britpart!) so I don't know what caused the poor running. I changed the fuel filter whilst I was there, and that has made a huge difference. It was done recently, so maybe it was doing it's job well? Bad fuel? But, the series pump fits, though the inputs are different, and I suspect the flow rate would be entirely adequate. I think I'll order an AC rebuild kit for the series pump, just in case there is crud in the innards. G.

That's really good to hear. Thank you. G.

I'm going with this one, it USP is that it's not britpart, plus it's cheaper to buy from their shop than their ebay page. http://www.motoradsonline.co.uk/products/Landrover-Series-3-Heater-matrix.html

It leaks. The heater chucks out a lot of heat, but it's moist water reeking of antifreeze. The problem is the duct in the lower dash, that's blocked up with decaying foam. If I can stop the leak, then that's the engine side clear. G.
