Thread: Heater core 1997 Disco.. DIY or Workshop ?

Dears LR Doctors,

following these steps as showed in the photos posted.
Is it possible to replace the O-rings between the firewall and the heater pipes?
avoiding dashboard removal.


cheers

Fitting as the always say is in the reverse order..

Hi Darren

I am doing exactly this on a D2, and it looks practically identical, I have 2 questions, and bearing in mind the D2 may be diferent I understand you may not be able to help.

The 2 heater pipes are attached to the firewall by a bracket that appears to be screwed on from the engine bay side is the D1 the same and if yes, did you remove this bracket and how?

2nd question if you did not remove this bracket how did you actually pull the pipes out enough, is it just a case of be brave and use brute force?

I have a leaky heater core in my D1... these pics seem to show that its located on the drivers side but im leaking coolant on the passenger side floor. :/ is this normal? lol

Could be a leak in the tank/cores on the passenger side, as the unit rides over the trans tunnel. It's only the feed/return lines on the driver side.

I don't even want to look at mine ('95 Classic) as its not the core thats leaking, but the two pipes as they come through the firewall - Engine side. Well, what is left of them.... both corroded to nothingness inside the hoses and now bypassed.
So far this winter there's enough heat permeating through the firewall to keep me from freezing!
Those two little pipes co$t almost as much as a core....

My D1 core was leaking coolant onto the floor on both sides of the console!

Hi,

Is this procedure the same if the disco has or has not got aircon? I have a 1995 D1.

Thanks,
Hugh

A Disco without aircon?

Mine was a '95 an I used this method.
