Heater core information, coolant leak, bypass, replacement, hoses, etc. - VOTD

Heater core bypass: 10 to 30 minutes ($10 / $110 / $160)
If the heater core in your car is leaking, you need to replace the core or bypass it. Allowing it to leak another day is playing coolant roulette. Don't do it, you won't win.

Awesome video! After owning a 1980 240 and a 1995 940 I have come to the conclusion that the heater core design is the single biggest mistake Volvo ever made. Both of mine have leaked... and I took apart the 240 to put in a new heater core - and it was a LOT of work. But your bypass solution is great to get around the all weekend chore of putting in a new heater core. So thanks!

[@RobertDIY]

I wouldn't say it was a mistake. All things will break or leak sooner or later.

You are a lifesaver. I have an S80 and a bad heater core leak. I've been playing roulette for a few months and just keep feeding the car coolant. The car has other issues, but I'm running it into the ground so I'm only concerned with prolonging the life of the car til I can get another one. This should do the trick. Thanks so much for posting this.

lol u still got it? if not what happened? i have an s80 T6 just trying to predict my future

[@TBarneck]

[@hsiehkanusea]

Thanks Robert. 5/8" heater hose and two clamps worked fine today in a '96 850. To disconnect from firewall: pushed in, then used long angled pliers to depress both ears of the yellow clip with one hand, and pull on the hose with the other hand. Appreciate your videos.

[@RobertDIY]

+hsiehkanusea Glad you got it bypassed.

[@mr_aliff]

[@RobertDIY]

thanks for watching.

[@haewien]

And Robert! Just a suggestion. If you have to replace the heater core, disconnect those hoses, grab a small diameter tube, push it into the hole until it stops, get a syrenge, plug the tube onto it, and you can suck out the coolant. Doing it right will prevent the coolant to flow into the cabin, or just a few drop will come out from the heater core. Now you can remove the heater core, and unplug everything. Cheers

[@RobertDIY]

No need to remove the hoses to replace the heater core. Messing with the hoses will only cause you problems.

[@haewien]

Robert DIY but you have to remove the core if you want to replace it :) than the coolant will flow out from it, right into the cabin. (Or is it called header matrix in the US?) Sorry, I dont know, the hood called bonnet here, gas station is servo, etc xD

You are my favorite guy on you tube about volvos. I'm always glad when I Google a question & it is you that shows up. I'm a woman that works as much as possible on my own volvo. I use to have a 98. That got almost 400,000 miles. Now I have a 2002 v70-t5. Have had it for 2 years. Love it but it has had more problems than my 98 did. It also seems harder to work on than my 98 was.

Your knowledge is invaluable thank you I’m now confident to attempt a swap myself

[@RobertDIY]

cool

[@steveclujhawkins8063]

Robert : Thank you for the VERY detailed video on this issue. My Volvo (98 V70) had an engine swap & the #%!?? that performed the swap failed to disconnect the 2 hoses from the firewall. I eventually determined that the heater core tubes just inside the firewall were damaged when the engine was ripped out & used your bypass method as a fix until i can replace the core. PLEASE tell your many followers to KNOW WHO THEY ARE DEALING WITH. Drug addicts (i caught them smoking whatever out back of their shop) make lousy mechanics.

[@RobertDIY]

+Steve Hawkins yes they do. 🤐

[@dreambuilder4536]

Thank you!!! Turns out I have one of those couplings in case it breaks already, would have preferred to be following your video on a full replacement but hey, broke is broke XD

[@RobertDIY]

🤦🏾‍♂️

[@neil3541]

So...Robert DIY...my problem..my son was driving the Volvo and what he thought was smoke started coming into the car. He stopped, 100 miles out, we got AAA to tow the car home. I found that the coolant reservoir was completely empty and entire radiator was empty, so suspected radiator hose break. Couldn't immediately find the leak so decided to refill the system to see where it was leaking. Kept filling the coolant reservoir from the hose waiting for it to come out of the top radiator hose. Thought it was a bit much water for engine and radiator but where else could it be going. Right? Hmm, discovered I had filled the whole car with about 6" water!!! Then I turned to the internet and found your video. Thanks. A little late but I have removed the heater hoses and will follow your clear instructions and install the heater bypass tomorrow. Spent the rest of my day wet-vac'ing the car out. LOL.

[@RobertDIY]

+Neil x ouch! Hopefully your son turned the engine off before it overheated. 🤓

[@jamie0]

Great video, Robert. I always enjoy and benefit from them. Attempted this myself yesterday on a 97 850 t5. Word of caution, you can't have a coolant hose clamp that close to the turbo, first day running the metal hose clamps got hot from the turbo's radiant heat and started to melt into the hose. I'm going to attempt to reverse my operation here at the gas station so I can get home. Then move the mod somewhere even further than where I tried to hold it using a zip tie.

[@RobertDIY]

+Jamison Kirk yikes!

[@jamie0]

Indeed. Turned out OK though. I let it cool down then ended up just pushing the hose on a little further (had enough hose) and re-installing the hose clamp. Of course, the key was being more aggressive to put the mod further from the turbo, about 8 inches, and used a bit of 12 gauge copper wire ( found on location 🙃, as in, the ground ) to secure it. Adventures in Volvo ownership. Hopefully I can get a good heater-core in this fall.

[@48perkins]

Thanks,replaced the heater core on my friends 98 volvo s70,it was real easy,he bought the core from Autozone for 61 bucks,took just a few hours.

[@RobertDIY]

Glad it worked out.

[@zx8401ztv]

Smashing video, as allways robert :-)) My mate used a short length of copper water pipe, the rubber hoses had no inserts so they slid over the copper pipe and two jubilee clamps were used, worked fine :-)) The bypass only had to last a short while untill the heater matrix was in stock. A light hat might help you, keeps the heat drilling into your head, i forgot and was bloody ill afterwards :-(

[@RobertDIY]

I have no idea why I don't like hats. I think they make me hotter and are gross once they get wet with sweat.

[@jopanel]

my heater core leaked and blew the head gasket. but i had paid for a engine rebuild from a local shop. they did a bypass and fixed it. thank god for warranty

[@RobertDIY]

They fixed the motor under a warranty?

[@jopanel]

yeah i litterally paid them to rebuild engine completely, it was almost $2000 for parts and labor. i got car back and 1 day later it blows a head gasket. they fixed everything for free.

[@RobertDIY]

Wow! I bet they won't make that mistake again.

[@RobertDIY]

Oh, they maid the cardinal mistake... you always fix the initial problem. So they fixed the motor because it blew the head gasket, and did not fix the cause of the first motor blow. That was NOT smart on their end.

[@vanessaskinner8355]

Love the instructions. I’m going out now to look at it myself. My only concern is that it filled the passenger side floor board up and when I add more it went straight threw to the floor. I hope it can be bypassed

[@roundedges2]

I picked up a salvaged 1998 c70 couple years ago running great except the heater core went. So glad to find your channel and feel even better about my investment. Liked & subscribed. Just need to find the short in the open door chime now. Maybe the leaking coolant.

[@RobertDIY]

Probably a bad door latch micro switch or bad relay.

[@roundedges2]

Robert DIY It is the same circuit as the dome light interior lights, because when the fuse blows the inside lights also have no power as well as dinging from the open circuit. What’s strange is, I’ll replace the fuse and it won’t blow right away, but after driving a bit and go over just the right bump, short happens again and fuse blows. No idea how the short goes away awhile and I can put a new fuse which does not immediately blow until I drive awhile. Maybe needs to warm up exposed wire expand to make contact and cause the short. I ordered a short tracer tool to locate hopefully.

[@nihonkokusai]

best is to open the clamp and put water inside the heater core flush the coolant out saves the mess inside.

[@RobertDIY]

Interesting

[@roundedges2]

Good, but needed to show pushing and squeezing the clip to pull the hose out. For example, did you use a needle nose pliers to squeeze? Are you squeezing and pulling the hose at the same time?

[@RobertDIY]

Doesn't matter. At this point, the junction will not survive the disconnect, just replace it.

This advise is great thank you Robert. I had to place a copper pipe (bendable) inside the hoses to get this to work, the copper pipe is around 10mm while the hose is around 15mm- will it cause any problem with coolant flow or not an issue?

[@RobertDIY]

+Rob Green no issue except for no heat inside the car.

[@Romulan112]

Robert, coming home tonight, my windows kept fogging up. I have no sense of smell. If I take a white clean rag, if the heater is leaking, would the color be greenish? I did however leave my passenger side window open last night and it rained hard. Could it be the water leftover from that?

[@dno440]

Just wanted to share with my 1997 Volvo 850 T5 had a leak from the heater core and I bypassed it then the head gasket which I do believe was already weak blew, a Volvo tech said that the systems in these Volvos are set at a higher psi so I prob blew it from bypassing the heater core because the extra psi went to the engine :(

+Jay Dongieux AC line should have been metal.

Is this a common issue with older Volvos Robert?

[@RobertDIY]

Yes 🙃

@@RobertDIY thanks fella just done bypass on my V50 no leaks 48hrs on

[@savannahhernandez7510]

Robert DIY I just figured out how to bypass it on my 960 and I was wondering is there suppose to be antifreeze in the reserve tank cause I don't see any in mine but my car isn't over heating anymore and I did fill it up and I put it on park and pressed on the gas and antifreeze started to fill up the reserve tank again but it only did that once now I don't see anything. Do you know what this could be ? Or is that normal when you bypass a heater core ?

[@RobertDIY]

Blown head gasket.

[@savannahhernandez7510]

I hope not I still been driving it like that till this day

[@savannahhernandez7510]

Robert DIY you were right it was a leak in the head gasket!

[@pierrechu1]

[@RobertDIY]

+Pierre Chu fix it ASAP.

What if the carpet is damp but no odour from the vent? I have a 92 240 wagon

[@RobertDIY]

Water/rain leak.

[@cornstar1253]

Robert DIY Thanks for your quick reply. It's coolant, greasy and sweet tasting. Wondering if you think it could be the heatercore anyways?or maybe something cheaper. If I take it somewhere they may tell me the Hcore needs replacing when it might not. I think that the 240 job is 5-7 hours.

[@RobertDIY]

LOL, Yes it's the heater core.

[@RobertDIY]

I understand.

[@savannahhernandez7510]

Robert DIY Would this also work on my 1997 Volvo 960?

[@RobertDIY]

Probably not.

[@savannahhernandez7510]

Do you have any advice on how to do it on my 960?

[@RobertDIY]

+Savannah Hernandez no, the dash has to come out.

[@stragazzi]
