I know I’m a little late to the party, but if anyone is doing this job and struggling with getting the pipes out smoothly or if you end up bending your pipes there is a pretty awesome fix you can try. Basically you cut about an inch segment out of each of the heater pipes. MAKE SURE you keep the portion of each pipe that connects to the heater core intact with about 2-3 inches of pipe. Once, you’ve cut the heater pipes, remove the flanged ends from the vehicle and connect them to the new heater core OUTSIDE OF THE VEHICLE which will make it much easier to get the ring clamps on. Next, attach a piece of of hose onto the heater pipes and use a screw-ring clamp and tighten it down. Finally, install the new heater core with the two heater pipe ends already connected via ring clamp to the heater core and with two rubber hoses (~3” long) ring-clamped to each heater hose (Heater core + (2) heater flange pipe segments + (2) rubber ring-clamped hose segments). Once back in the vehicle you simple connect the rubber hose segments via an additional screw ring-clamp to the old aluminum heater core pipes.
Those heater core O-ring connection were the absolute worst to take apart and reconnect. Besides the flange clip stripping out (I wound up using a smaller screw with its own nut to replace the screw going into the threaded part), I had to fight a very rigid aluminum hosing setup. If those O-ring flanges don't line back up perfectly, good luck trying to get the clip onto them. I ultimately cut both aluminum hoses and installed them unto the core while it was out and then slide a rubber heater hose section over the cut with 2 hose clamps for each cut.
I just completed this job with help from this video and the one that lucky8 used to take apart the console. Here a couple of problems I ran into that might help other people. I Got everything tore apart fairly quickly. It was the original heater core in my 2001 D2. Hoses disconnected from the core without too much trouble. Now this is where things got tough for me. The new aftermarket heater core would not slide in the hole. I had my brother holding the dash back while tried to wrestle the thing in there. Finally ended up getting it halfway in. Ended up beating into place. It was way too tight. Anyways don't do that. I ended up bending the end of the core and when I went to put the hoses on it didn't line up at all. Yanked that back out and ordered another one. This one was visibly smaller and no insulation on it. It slid right in. But it did not come with o rings. I used the new o rings from to be other core. They were visibly bigger than the ones I took off of the old one. I figured the old ones were worn out. But something didn't seem right. When trying to get the hose in with the bigger o rings it was impossible. I took them back off. I went too Lowe's and got some that were slightly thinner. These worked well. Got the bottom hose on and clamped down no problem. The upper hose I couldn't get a good grip on it to seat the o ring. I thought I had it. I clamped it down started it up and the top hose was leaking at the connection. Pulled back apart and really pushed it in this and finally got there. So far so good. No leaks. Also just rip old clamps off its easier. I lost two o rings and one screw for the new clamp so you might want to get a couple extras. It's really tight. I hope this helps someone.
Hey there! I know I’m 9 months too late to your comment, but do you have a link to the second heater core that actually fit in the space? Or at least the name? Thanks in advance!
I've been searching for years for this video, and I have found it by accidnet. Thank you for putting this up. Can you do an evaporator video on a D1 or D2?
This will make you sell it... 🥴😫 I'm smelling burnt coolant and hearing a water/liquid gurgling sound while driving, coming from the area of the glove box. Are these core symptoms?
Did you use a OEM heater core? Would a after market one bolt right up... I am doubting it I believe these fittings for the heater core are range rover specific. Please comment as soon as possible thank you.
Thanks man helped so much!!! How do you disconnect the heater lines from the core, the lines are solid and not moving since they're aluminum and the core isn't budging either, I'm lost as to how they are supposed to come off
Yep. That's were my job failed. Why are the solid lines not built with any place to get out of their connection, is beyond me. Three days of trying. Destroyed the soft connections. No more heater for me. }#%^+£>
Is it the same for the right hand drive land rovers around the world or we have to take out the whole dash. I asked a mechanic and he wanted $3000 AUD to take out the whole dash and the an extra $500 AUD for the parts required
I appreciate this video but need detail of disconnecting and reconnecting the Inlet/Outlet Pipes. They have no room to pull back out of their connection. What am I doing wrong?
Green Achers your not doing anything wrong, its a frustrating job. You can place a screw driver in between the inlet/outlet and pry it toward the rear of the vehicle. You will be prying on the solid tank of the heater core. DO NOT pry on the mating surface of the pipes. Also dont apply alot of pressure as the heater box is made of plastic. But this may get you the movement to separate the lines from the heater core. Other than that, you will just have to get creative and improvise, sometimes normal methods will not work, sometimes they just dont want to come out.
I did as you advised and the gental bend in the lines while pulling the old core out, made them not align into the new core. Ruined the new one while trying to get them clapped. Throwing in the towel and parting it out, in my defeat.
That sucks man, you shoulnt have had to pry on the pips at all, you would have been prying on the old heater core so the pips would come lose from the old heater core. I have never caused a pipe to bend.

Thanks, about to start this now!
This wasn't too late for me... thanks!

I don't remember but I know it was cheaper than the one that did not fit!

Great video! I am planning to do my heater core this week.
This will make you sell it... 🥴😫 I'm smelling burnt coolant and hearing a water/liquid gurgling sound while driving, coming from the area of the glove box. Are these core symptoms?
Nice run down... thanks!!👍
Great video thanks

I havnt worked with a right hand drive, i wouldnt beable to let you know if its the same
Cheers mate! 🍻

No shit, thank you.
