I have a 1999 Volvo V70 xc. I followed the instructions. It took me 45 Minutes. Great Resource. I would like to add if you put the vehicle at an incline with the front of the car going down hill you can save your self time draining the coolant. By doing this I did not need to drain my coolant. I only had coolant from the heater core which was very little. When you take heater core out grab both sides and pull down and back.

Just bought my 1999 S80 and I am sooooo glad that I googled this site!! Thanks so much for solving this problem. I have my boyfriend the mechanic with me when I got this car from a craigslist dealer. After having the car checked out, found out that I needed an new radiator. we just flushed out the radiator and spent about 100 bucks on stop gap and antifreeze, all to no avail. Water ran clean-no antifreeze left either. We see the spot where the leak is coming from, and after seeing that this is a constant issue with this vehicle, I'm happy to know that there is a solution. She runs great otherwise. Thanks again for the post!! (IMG:style_emoticons/default/57.gif) (IMG:style_emoticons/default/460.gif) (IMG:style_emoticons/default/clap.gif)

These are the screws that need to be removed. 5 in total.

Only the one in the top left. Do this on both sides of the "sarcophagus"
(IMG:http://i14.photobucket.com/albums/a306/baustin420/heater_core_replacement/2008-08-01_heater_core_015.jpg)

And this one that is hidden by the grey cable. Again, do this on both sides
(IMG:http://i14.photobucket.com/albums/a306/baustin420/heater_core_replacement/2008-08-01_heater_core_009.jpg)

And the one that holds the 2 tubes in place.

I didn't take any pictures after this, but everything basically goes in reverse after that. I refilled with new coolant and she seems to be running great! No drippage and the "sweet" smell is gone!

Hope this helps somebody like ya'll helped me!


The 2 small side screws are T15 the larger 3 screws are T25 and they are the two on top and the one tube screw.

Ok, So I am digging up an old post, but I need a question answered. Do you remember how easy or bad it was to ge tthe core out from its little nook after all screws are out? I am about to undergo this process and saw that 2 people had asked withough getting responses. I know it was 2 years ago you made this post, but I hoped that either the person that started it, or someone that has done this knows the difficulty of getting the old core out.

It is quite simple. Here is the tip (IMG:style_emoticons/default/wink.gif)
First remove le A/C drain black hose at the bottom
(IMG:http://i299.photobucket.com/albums/mm294/v70r2k/110603090.jpg)
then remove the middle screw between the two pipes
(IMG:http://i299.photobucket.com/albums/mm294/v70r2k/110603081.jpg)
(IMG:http://i299.photobucket.com/albums/mm294/v70r2k/2008-08-01_heater_core_014.jpg)
Then remove the 4 screws holding it to the top section and pull it down a bit
(IMG:http://i299.photobucket.com/albums/mm294/v70r2k/110603092.jpg)
then a the same time you continue to bring it down rotate the bottom toward the rear of the car
(IMG:http://i299.photobucket.com/albums/mm294/v70r2k/110603095.jpg)
(IMG:http://i299.photobucket.com/albums/mm294/v70r2k/110603098.jpg)
and pull it in front of the pedals
(IMG:http://i299.photobucket.com/albums/mm294/v70r2k/110603099.jpg)
It will go out quite easy

Thank you soooo much for this post. I just changed my heatercore on my 98 s70. The pictures helped a lot! It took me about an hour. I didnt drain the coolant. I just clamped the hoses on the engine side. It worked great. I did remove the kick panels for easier access. You guys saved me some serious $$.

Thanks for this very helpful posting. Can you tell me the best way to clean the carpeting that has the antifreeze stains from the leaky heater core? Thank you.

I just replaced the heater core in my 1998 V70 today, and this post really helped. I was able to buy a core with the two O rings and a strip of adhesive padding on eBay for only $60. The plastic parts are black instead of pale yellow, but it fits perfectly.

But don't be fooled - this is no one or two hour job if it is your first time doing it. It took me 5 hours to figure everything out and complete the job. Some things that took extra time:
1. Disconnecting the battery so it wouldn't go dead with the doors open for so long.
2. Removing the plastic shield behind the front bumper so I could drain the coolant. (Getting it back on single-handed is not easy.)
3. Mopping up the coolant that leaked out of the old core.

Also, there were a crucial couple of steps missing from this post: to get the passenger side carpet out of the way, you have to remove the kick panel below the glove box. That was not trivial; no screws are visible (unlike the one on the driver's side, where there is an obvious screw just below the steering wheel.)

After doing much searching on line, I found out how to do it. You must remove the glove box.
1. Open the glove box. Locate the arched plastic pieces that hold the door.
2. With a very tiny flat blade screwdriver, push down in the small opening at the right of the each piece where it enters the door. This will push it up and out of the door.
3. Remove the 6 Torx screws (2 along the top, 4 along the bottom) that hold the glove box to the dash.
4. Grip the box at each side and pull it out of the dash. It's just a press-fit. There is a clip behind the box slightly left of center, which holds it in.
5. Once the box is out, you will see two screws which are holding the kick panel in place. Remove them.
6. (Putting the glove box back in is a little tricky. Take note of where the clip is that snaps onto the rear of the box. If you put your hand at the rear of the box and push firmly, it will snap into place.)
7. Carefully pry off the wire socket that goes to the light in the kick panel. Now you can remove the kick panel. (Replacing each panel at the end of the job was another time-consuming part for me. They have to be positioned very carefully to fit.)

To get the carpet out of the way is also time consuming:
1. I removed the front bolts that hold the seat tracks to the floor, and loosened the rear bolts. This let me rock the seats back.
2. I also removed the plastic trim pieces along the inner edges of the doors. They snap out easily.
3. There is a heater duct under the front of each seat. While the seat is tipped back, you can pull the carpet over this duct, or make a small cut to make it clear. Then, you can pull the carpet away from the center console, and 'roll' it away from the area where you will be working. It's stiff, and probably soaked with antifreeze (mine was), so be patient.

After removing the screws from the 'sarcophagus' holding the heater core, I had a tough time getting the core out. I rotated it toward the rear of the car, as this post suggests, but it was very tight because of two rubber tubes under it. After I forced it out, I realized that those tubes can be moved out of the way first.
1. The one to the right is, I believe, the drain for the A/C. Pull it up and off the nipple and bend it over to the right and out of the way.
2. The other one is just a rubber sleeve that can be easily slid toward you and out of the way.

The bottom of the core itself is held to the white plastic shell by four screws. Getting it back into its place under the dash is an exercise in patience. I must have moved from one side of the car to the other 10 times before I got it right.

I hope all this helps someone. Let me know.

bought the heater core with two extra O rings (just in case)at FCP Euro for $65 total w/shipping, read all of the posts here, Baustin, Volvamos, you do need to remove the glove box, remove the kick panels in the foot wells, you do not need to remove seats, you do not need to drain the radiater, just peel back the carpet, pop the black rubber condensate drain out of the floor directly below the heater core and remove the plastic connector that will likely still be there by pulling straight up, this will make it much easier to move the old core out and the new core in, I used two plastic kitchen trash bags one inside the other and put under the heater core connection on the drivers side, loosen the heater core screws described on the passener side first then move to the drivers side, last screw out should be the one holding the heater core pipes (parallel with the core and the lowest one) when you pop the heater core loose you will get about a gallon of anitfreeze, work the old core out from the passenger side, MAKE SURE TO WASH THE NEW CORE WITH SOAP AND WATER TO REMOVE THE PACKING OIL AT LEAST ONCE AND AT LEAST A DAY AHEAD OF TIME AND LET DRY, install the foam gasket around the new core, remove the bag full of antifreeze from the drivers side and carefully put in an old windsheild washer bottle that has been rinsed out, wipe down all surface that you will be reconnecting to, install the two new O-rings, install the new heater core, i had to get the upper screws in before I could get the pipes to line up enough to get the lowest screw in, this took a little wrangling and a few choice words, once you have all of the heater core parts installed, fill up the antifreeze tank with the fluid that you have in the windsheild washer bottle, or new stuff if it looks bad, start the car, watch the antifreeze bottle and keep putting fluid in as it goes down, if it looks like it is going to overflow put the cap on and let the car get to normal operating temperature so the thermostat will open, inspect the interior for any leaks, turn the car off and let it cool, replace all of the interior components, carpet , glove box etc, in an hour or two the antifreeeze tank should be low enough to put in the remainder of the antifreeze
I read posts and "How To's" for about two hours, took me an hour and twenty minutes to actually do the work.

Excellent post! I am a thirty year plus mechanic and found your pics and thoughts very helpful.The core and box didn't want to come out as an assemby. I used a TORX bit and wratchet wrench to remove the lower housing screws. A pain but worth it not to tear stuff up. Thanks again for the post.

I admit I have been surfing these boards for a long time and never signed up but felt compelled to after I just completed this heater core fix in about 30 minutes. THANKS to the OP for the play by play with pics and everything. Another shout out to the rest of you for making it even easier with suggestions along the way (especially clamping the heater core hoses). I drive the 99 V70 which I bought for my wife about 10 years ago. It had 90K miles on it then and now its just shy of 250K. This has been the easiest car to care for I think I have ever owned. I have completed all the regular maintenance (oil,filter,AC Recharges,Timing Belt) with no problems. My local mechanic has done the shocks, struts and tie rods for me. I think I will be putting new steering control arms (or whatever they are called) soon as well but its fine for now. We just bought our second Volvo. Its a 2006 XC90 with the 2.5 cyl turbo in it and Im hoping for as good of luck with it as we have had with the wagon. I am a member of several forums (ford truck, dodge truck, several archery and huunting forums. This is a great place you have here and I plan to contribute all I can when I can, Keep up the good work folks!!! PS: I got my heater core from Ebay for $47 with free shipping thanks to you guys (:

Great post. Thanks! Just have one thing to add. If you have a V70R, you will need to remove the dolby prologic unit that sits in a bracket behind the heater core and then swing up the support bracket so it is out of the way. Took me about 5 tries before I realized that the heater core could not be removed until this thing was out of the way. Now, I just need to figure out a good way to dry out the pad that is under the carpet!
