I just bought a 1992 RR in pristine condition with only 107K miles for a ski and camping car. I bought it knowing that the heater core had been bypassed due to leaking and came with the new core in a box. That said, it was 22 and snowing yesterday and I would like to have the heat, especially since it has been garaged for many years and now is outside. (Too tall for the garage.)

I have seen some testimonials and read everything from this forum about replacing this part. I just wanted to gat a 4th and 5th opinion from here if I could. I am very handy and work on lots of cars in my spare time.

Thanks for your help. I have a few other questions as well and will post under separate subject heading for better navigation. --Doug

I've replaced a couple blower motors and you have the entire heater box removed. Here's a link to instructions, http://www.roverparts.com/Instruction%2 ... K-8844.pdf

Follow them and be careful, lots of work. The last one took me about 8 hours and a six-pack (optional). I'm sure some pros have some shortcuts to make it go faster. Don't get in a hurry. You should replace the blower while you're in this deep. You'll be glad you did. Hope this helps.

thanks for the information. It looks daunting but doable at a steady pace. I found a shortcut I am looking into that requires a small incision in the dash supports where you can pull it out of the right side foot well. not sure which to follow yet. it will be a few weeks before i get to it with the impending holidays.

I don't see how that's possible but I'll look at the instructions again to see if I missed a shortcut. The heater core is completely enclosed in the heater box with the blower motor and some dampers and linkages. Wouldn't really help me with anything right at the moment, my bad luck seems to be blower motors. I just always replace the heater core at the same time since it's a pain and already removed to get to the motor. Cheap insurance. I always wanted to buy an entire heater box and have it ready to put right back as soon as the old one comes out. They just haven't been around when I needed one. I have a couple ideas where to look if that sound appealing to you.

Here is the link that has the instructions for the shortcut, but upon further inspection it is for the 4.0/4.25 generation. Looks like I am in for the full meal deal. I wil probably do it myself, as I know the dealer or shop will give this job to the grunt and I think this is going to take csome very careful finness. I'll order the new fan motor now as well to have it on hand for when I begin the job. thank you.

It's not a hard job if you take your time. Label anything that you have to disconnect. I use yellow electrical tape and a sharpie so it's easy to spot things. It will probably help to take lots of pictures. Be sure you know the radio code before you start too. Good luck.

ok, to close the loop on this thread, i installed the new heater core on Monday and it took me 12 hours. I took my time though. It is not a difficult job if you are used to manipulating car panels and have a good set of tools. the most difficult items I endurred was reassembling the heater bax with the new core and then replacing the heater hoses in the engine compartment. That was a bear of a job. Those hoses did not want to get on the nipples and there is virtually zero clearance behind the motor for the lower hose. A better practice would likely be to instal the hoses to the housing before it is secures to the firewall so you can do it from the inside.

Long story short, I used the 48 page tutorial from British Atlantic and went to town. I have heat and everything is working now! i am a happy camper.
