This video is a lifesaver! My heater core, or some connection to it, decided to spill all the coolant a mere few hours ago which left me rather despondent. But after having read my repair manual and watched your excellent video, I think I have the confidence to attempt to change it out. I have to genuinely extend my deepest gratitude to you!
Thanks Bill! I've been subscribed to you for years and am now an IBEW apprentice. I don't know much about cars, but the heater core on my '98 S70 failed and became undrivable due to windshield fogging...with the help of this video I was able to replace it myself. I knew if a fellow sparky could do it then so could I!
Best video on the Tube for tackling the heater core stuff on the volvo V70. Gotta have hose clamps....$15 and a torx bit set....$9 at the autozone here in the USA!
Thanks for his clear video, helped me complete the job in under 2 hours (I was changing the coolant at the same time so that included flushing and filling). The passenger floor was starting to get damp from leaks, I'll check again in a few weeks to see if the O rings are seated right. The new heater core came with a pair, but I noticed they were round and the original ones tapered so I re-used them as they were in good conddition. If there is a weep I know its just an hour to change them again. BTW that tube underneath is just a drain pipe, after fighting against it I just pulled it out and set it aside temporarily, plenty of space to do so.
I just did this service yesterday, I used the clamps, and that helped, however, I found that my heater core had lots of coolant in it, not the lines, the actual core. I wonder if this indicates some sort of clog? It was the original core, 25 years old. Glad I replaced, your video was a big help! Instead of pushing down on the evaporator tube, I just unplugged it, pull up firmly, easier with it out of the way!
@Sparky Channel. Great job and lesson Bill. You made it look easy to replace that heater core. I guess that keeps that Volvo running comfortably in the family for another 17 years? Hope you and your family stay safe and well.
Yes, that's the idea. I really like the idea of someone saving $600 or so on labor by watching my video! Did you notice that I read your Flexvolt Advantage question to Nate of DeWalt?
@@SparkyChannel Hi Bill. I meant to reply to that video on the Dewalt Flexvolt Advantage with Nate. Thanks for asking my question. Looks like it made it easier for you to get the better technical answer (less impedance) so more current can flow to get more power (watts). Great exchange with Nate. I really have a better understanding of the Flexvolt Advantage system. Thanks again.
@@ccadama I do too. Not too many people know it but DC brushless motors produce AC voltage and AC current. They call it phasor AC, phasor current and impedance instead of resistance. Ohm's law still applies but it is IZ=V where Z is impedance instead of resistance. Phasor because it's sine wave form.
Good video. Simple and to the point 👌 My s70 heater works sometimes (barely) but most the time not. Hopefully it's something simple. Maybe the fact it's 17 degrees for the high lately has an effect ha but if it comes down to the heater core, this video will be of much use.
I love you! Haha but seriously thank you so much for making this video! It was so helpful, I'd rather work on my cars myself and this seems easy enough for me! Thank you soooo much!
@@SparkyChannel I have not done it yet unfortunately. My 98 v70 was given to me not long ago and it needs some work. Runs good but needs an tune up (learning to do myself). I've suspected the heater core was going bad due to lack of heat coming out but being 22 years old I'm going to replace it anyway. RUclips has been my heaven sent haha. I can't tell you how much I appreciate people like you that post videos like this to help those who try to do the work themselves.
I have a 2015 XC70 T6 1. Would this be the same process. 2. I started to have a problem with the heating system (No air on the drivers side) after a tech changed my air cabin filter. Is it possible the problems could have been from a poor replacement process?
The procedure should be similar but I don't know for sure. Perhaps a viewer with your model will write in. I don't think changing a cabin air filter would damage your heater core but then I don't know what they did.
@@SparkyChannel thank you! I just purchased a 97 850, the water pump appears to be original, but no leaks, should I replace it as preventative, or just wait until needed?
@@peterhandelson1193 Yes, I would replace it. This is because it can cause damage to your engine if it stops pumping properly. If it's that old, I would say replace it. Also, congrats on buying a quality car!
@@delukxy I used 2 of these clamps: Fuel Line Clamp Set, Hose Pinch Off Pliers for Radiator, Brake, Coolant and Gas Line, Red (3 Sizes): Amazon: amzn.to/3QW9tG6 They were different sizes, but it didn't matter. It worked fine.
4:10 this rubber hose with the flat flange under the heater core can be unplugged and put aside, then you have plenty of room to get the core out.

Right on, that's awesome! You have a nice car!
Thanks for this. Perfectly clear and detailed video. Did the job for the first time ever in less than an hour. Thanks again!
Great to hear! Excellent job Paul!

Thanks so much! Yes, hose clamps and a torx set are what you need, for sure. And a socket set. You can do it! :)

Thank you for the clear video. Question: Didn't the old heater core have a build date of 2010?
Thanks. Yes, apparently so.
This is great. Can you get at the A/C evaporator without removing the dash, as well ?
Best video on RUclips. 👍🏻🏴🇬🇪🇺🇸
Thanks so much!
@@SparkyChannel My pleasure. Best Wishes. 🏴🇬🇧✌️🇺🇸 Didn’t realise that I’d included the Georgian Flag but I’m English from the original England.

You are so welcome! This is a very expensive repair when done by a garage, so I understand! Have you done the repair yet?

Super good instruction video❤
Glad it was helpful!
Wow that is much easier than my mustang
Yes, it's not bad.
nice job
Thanks!
I can't find the link for the clamps
