Thread: Replacing heater matrix, got an idea

That is how I do them, turns out to be around 4 hours from go to whoa instead of 10 hours...

"...why rover designed this system the way they did...."

The phrase 'God only knows' springs to mind.... NO-one else has a chance !

Because they're incompetent. Or wilfully ignorant. Or stupid. Take your pick.


I shudder to imagine what my softdash matrix will end up like. Was underwhelmed when I bought it. Warm, but not HOT like a Paj or Patrol. Soon after I noticed the pipes inside the firewall were corroded to powder so it's bypassed out of circuit,

Thanks Justinc, will look at something similar if/when I'm forced into fixing mine...

That solution does work well, the core/matrix slides out the drivers side with only a few brackets removed (on a 95 D1). With mine I only cut out enough aluminium pipe to be able to slide a section of heater hose to join them back up, but whatever works. A fair few people on this forum have done it that way - I managed to find enough info and links over a few different posts to be able to do the job.

Having never done one, is it possible to cut the pipes in-situ for the first time it has to be done ?

Yes, I use a small air hacksaw.

So I didn't remove the dash, I did the heater core as described elsewhere on this forum.

I had to replace the pipes as some heavy handed individual had cut them off. I hate cutting anything so I usually don't. To replace the pipes I had to remove the clamp plate where the head of the screw was on the firewall side and therefore inaccessible.

I drilled that screw out with a long series drill and, before reassembly, brazed a nut onto the other side. Anyone who ever has to replace it again (Hi, Laurie) can remove it easily.

This is the forum method of heater core replacement for the D1 update. Heater core 1997 Disco.. DIY or Workshop ?
