jca25 1,034 Posted September 26, 2014 Here is a bit of a rundown on the replacement of the heater core. It was done on an XD so could change slightly between models. I didn't take the photos when i pulled it apart so these are only when it was put back in. All the screws around the outside need to be undone. It is also stuck together with a sicaflex type glue. This is the inside of the heater box, there is normally an air con evaporator on the rhs but im not running air con any more so its been pulled out. The heater core just pulls out of the box The insulator rubber just slips off and on over the top Note the one pipe that has the curve in it. It needs to go to the top of the heater box when put back in. While you have it apart you might as well refoam the flaps. I used a 10mm square that i got from spotlight with a spray on glue When putting it all back together just use a bead of silicone to seal it 3 JGP, steve mcqueen and Outback Jack reacted to this Share this post Link to post Share on other sites

Ando81 2,949 Posted January 16, 2015 I have been dreading doing this job in my xf sedan. Can anyone tell me how long it would take to remove the dash and heater box to do it. I'm reasonably handy on the tools but patience is my biggest downfall. I need to get it done so I can drive the car more often than I do, got 45days on my club rego and didn't drive it more than 8 times last year. Share this post Link to post Share on other sites
Mr Polson 10,214 Posted January 16, 2015 An hour to two hours for removal. Better to remove with two people. Windscreen demister trim out, screws under window undone. A really long Phillips head is handy for that. Two bolts in the middle of the dash in front of the console (which needs to be removed) and two bolts either side of the dash behind each kick panel. Steering column needs to be removed or dropped onto the seat (two nuts under the trim panel for it). Undo as many plugs as you can before removing dash, but some you need the dash half out to unplug. Don't stress too much about which one came from where as they all are unique. Heater box is disconnect hoses, A/C if applicable and undo the nuts holding it in from the firewall in the engine bay. One is right in the middle of the car from memory too. Share this post Link to post Share on other sites
Ando81 2,949 Posted January 16, 2015 Cheers, I did read a sticky somewhere either on here or xfalcon which made it look simpler. I've got a mate keen to help me and he has pulled a few out of cars for his speedway cars so maybe we should rip into it one weekend. Share this post Link to post Share on other sites
Nath 1,975 Posted January 19, 2015 Let us know how it goes - I may need to do mine at some point... Dreading it. Wanna know how many beers the task will require. Share this post Link to post Share on other sites
Ando81 2,949 Posted January 19, 2015 Well mate, I'm really dreading it and work is gunna be hectic for the next 6 weeks so you might beat me to it. 1 Nath reacted to this Share this post Link to post Share on other sites
jca25 1,034 Posted January 20, 2015 Its not as bad as every1 thinks main thing is take your time pulling the dash out and putting back in so you make sure you get all the bolts so you don't break any of the dash as they are getting harder to find in gc so they don't rattle 1 steve mcqueen reacted to this Share this post Link to post Share on other sites

Take pics or video as you go along so you have a reference to go back to when your putting it back together. You'll be fine, just go easy and take your time. 1 jca25 reacted to this Share this post Link to post Share on other sites
