Volvo S60 and V70 Heater Core Replacement. How To Get It Done Fast! 

Hey Eric, I know you’re sick of the P2 Volvo but I really appreciate these videos when you share your experiences and knowledge about these cars. All the best from Sweden!

I used a high power blower under the hood to blow all the coolant out of the heater core once the heater core lines were disconnected. Just blew it in one pipe and it all came out the other pipe. Worked like a charm. When I disconnected the heater core from the heater core pipes under the dash, it was empty. No mess.

Excellent! Thank you so much! Going to give it a try this weekend.

Great video, thanks. I changed my heater core on my RHD 2006 S60. Very similar, but go in from the passenger side, removing glovebox. I had to cut away a hidden piece of dash, and a bit of the white plastic housing behind the glovebox. Easy to make good after. That was four years ago, and the O rings are now leaking a bit, so I watched this to familiarise myself with it all!

Huge thanks for sharing this video Eric. Looking at you gave me enough courageous to start this job myself instead of paying serious money to get it fixed. Keep up your amazing video’s.

Awesome video. Doing this right now - as for coolant/carpet, I'm keeping the mat in there - easier to clean the mat than the carpet, no? (Though 1 - 2x per year I rent a steam cleaner - with upholstery attachment - and detail my "fleet" interiors anyway.) I put a kitchen garbage bag under the mat, then the mat, then another bag, then a crapload of old frayed bath towels. And my spaghetti cooking pan, which is small, both of which illustrate I'm single, no disagreements over being able to remove toxic antifreeze from a cooking utensil... So far so good.

Perfect, will save me a ton of trouble. My S60 has started to leak there, now i know how to fix it without any headaches! Thanks a lot!

Nice video. Certainly it will help me to repair my Volvo. I had a coolent level reduction like 6 months ago, I completed it and everything was fine. Until this Sunday when I felt the carpets being wet! Removed the carpet, drove for a half a day and was no leak detectable on the console or anywhere. Its true that I havent used the heating in the car. Found this video and I will check tomorrow in details by removing the covers.

I helped a buddy change the heater cord in a 1979 TRANS AM. What a chore.

Wonderful style and content. Keeping it real (ly great!) Thank you.

Thanks for the video. Easy fix is always the way to go.

This will be hard for most folks to believe, but that coolant is really all you need for any vehicle. In many cases, it's superior to the OEM formulation, including Volvo's OEM coolant because Volvo coolant contains silicates that destroy the water pump bearing. Any house brand extended life universal coolant will work, but Napa 1EXT and RTU1EXT are the best values when on sale (which is quite frequently).

thanks a lot. This is premium service

Usually Volvo v70 is easy car to work on but this was hardest thing I have done

It was my understanding that before you disconnected anything, the heater was supposed to be set to the maximum and the blower was to be turned on full blast. The goal? This was so that the heater ventilation door armatures would move out of the way, thus obtaining more room to remove those clips.

I'd like to add, it bends the fins pretty badly clearing a part of the steering column. They look like they are held on by a couple t-40's. May prevent too much bending on the fins putting the new one in. Also, FCP euro for o-rings and clips if yours didn't come with them. The Behr/Mahle heater core didn't come with any, and those o-rings looked specific versus the ones that came out. Just my 2 cents! thanks!

Great job! Thanks for this video.

Great video 👍

about those clips it realy matters,specely the one on top because wenn you put those in oterwise it wil block those heater valve arms.find out my self !!

In many cases you need to remove orings and if its still leaking you may remove heater. I guess ist chipper. Greatings and sorry for my language.

Great video. I’m about to do this as my heater core has been flushed twice. Thanks for the help. Can you give any advice on how to fix a faulty blender door or actuator? My defroster setting doesn’t work-no air! I can’t find anything online….any help would be appreciated! Thanks again!

you this also be the same configuration and process for the s60 2001 sedan ? under my drivers side floor carpet it is GLOWING green! .. and leak is half way down the car underside.. on drivers side!.. grommets? and heater core?

I’ve got a question….should you flush the entire system prior to replacing the heater core? Appreciate your input. My new heater core says a flush is required before install or warranty will be voided. I don’t want to do it twice 😂

$18 bucks for the Heater core? You must have got that on line. Anyway FANTASTIC VIDEO!!!.. I replaced the H.C. in my 01 S80...but having a REAL problem putting the clips back in. I tried bending them back to as close as possible to the way they came out, but no luck. Any advice you can give? The lines are well seated in the H.C....the clips just will not pass all the way thru. By the way what are those thin silver legs with black boots on them. I accidentally pulled the right side out...seems like it has a hole at the end where I can just slip it back over a peg or something... but it is in a blind spot. Would appreciate your expertise. 🤔

Does these heater are known to broke as on the 850's?

Hi there, could this part be the reason for the weak heating of the vehicle? I don't have a fluid leak here, but the car only warms poorly inside. I have the main cooler/radiator replaced by the service. Unfortunately, the car still heats poorly. Operating temperature at 90 celsius as it should be. Thanks in advance for the advice

Does it make any difference to the job if the car has air con ?

How did you get that brake switch clip out?? Already broke something close to it and it won’t come out and don’t really explain where the clips are or from need help asap

Hey. I saw they removed whole dashboard for change the core. What’s the difference?

Mine is leaking on the passenger side 2007 s60, then its anti freeze mix with oil. Any pointers?

The flat mechanical arm to the left of the core snapped because the core got him up on it. What is this piece?

I've spent 4 hours attempting to get the top pin back in. Impossible. How did you do it?

Oh man, all i wanted was to see how to get those dam clips in...ive tried almost everything and im getting very frustrated

Can this work with the 2007 s40 T5

skipping the part about how to pull the electrical cord out rite an not un screwing the one bolt to move the steering wheel up is crazy those are definitely the most important parts when your trying to get it in or out 🤦🏾‍♂️

EDIT: content creator does not advise the following. I got frustrated and used a hammer after splitting two pins trying to get them in without one. As of one test drive, they are not leaking even though the bottom pipe is mangled and it's o ring is held in place by two halves of a broken pin. For anyone in the future who watches this, the part where he just skipped forward and it was night time and all of a sudden those little pins were in... Yeah that's the hardest part of the job. Search for peppermint Volvo S60 heater core replacement, he goes into much more detail and shows the entire procedure for how to get those pins to set. The trick is is you need to tap on the 90° bend on those aluminum pipes with a hammer. You need to hit it until you can no longer see the o ring. Don't smash it too hard or it will indent the 90 (ask me how I know). Use a small block of wood if you're starting to damage the pipe.
