My Brother's Outback Overheated! 2010-2014 Subaru Outback Radiator Replacement! Easy DIY! 

It never get old to me seeing this work being done. I see something new each time. Thanks for the videos you post.👍

I love these hands-on videos! Cannot wait for the engine re-seal!

You can use neutral soapy water to help with the RAD hose seating. That's what we use at the factory.

I enjoyed watching that repair! Good job and your brother is lucky your around.

Your such a nice brother for fixing his car.

In Argentina we get the "made in Japan" parts. The radiators cames with the new foam attached.

Thanks for another great video!! Exact same failure happened to my 2010 2.5i premium. All the broken bits were in the top of the radiator got very lucky.

You need to rush out and get a lottery ticket NOW! LOLOL! Finding those broken plastic barb pieces was luck that I'd never have...

Thanks for the video. I'm working on my Subaru outback exhaust changing the CV boots ball joints rear bushing end links and timing belt. Have to get the holding tool.

Awesome video just what I needed to do the job thanks

I may to drive daughters down and have someone who know their stuff go through it, great job

Pretty cool video thank you for posting it

That foam piece on the radiator is a separate piece and costs around $10. Peeling it off the old radiator and sticking it onto the new one is the way to go.

Nice video and excellent attention to detail. Any chance you could do a short on who makes the Matco flare nut wrenches. While they only average $20 more a set than the gear wrench if the oem manufacturer sells them cheaper it would be much appreciated.

hopefully you have prolonged engine pull and HG replacement until you have more time. keep the videos coming.

Hello from Russia!

AAA batteries will fit snugly into those CVT lines. If you need to plug them for some reason.

2011 subi legacy here! i had the exact same failure point and after talking to people on forums it seems to be common!

Great video 👍 👍

I’ve had the coolant conditioner help with external leaks but not with exhaust gases entering the coolant.

Thank you!

It's funny in my owner manual it calls for the special subaru coolant additives aka bars stop leak when I do my first coolant change on my 3.6 ...

I replaced my upper hose and everything was good. 2 days later that upper radiator barb snapped off showering my engine bay with coolant. New radiator on the way but I want to be sure there are no chunks of the barb circulating in my coolant system. Is it best to pull the thermostat to be sure?

ya timing ay, i just ordered a new radiator as still getting warm engine temp on the hills an at times under load.. nothing is indicating the head gasket, so will try the new radiator , worst case. its the HG somewhere

The cooling system conditioner worked it's magic? Curious if that product is a head gasket sealer or just a radiator sealer....

Have same issue. Hose popped. But no overheating. Caught right away got fluid and drove home. Still running at temp. Parked at home Started testing. Upper and lower heating the same as mentioned in other video. Pressure tested radiator would drop to 13lb and hold for a while but eventually would lose Pressure. Getting some bubbles when gets to temp. Shut down and tested pressures at temp and got hose to pop again at 14psi. Didn't know about barb until watched this episode. Will check tonight. Just like you timing sucks for hg job. Will try what you did ,just curious. Its been 8 months. Update on your brother's outback? 2012, 2L EJ. 180k

Hi! I'm trying to figure out whether there's a way to mount a DEFA engine heater in the plug at the bottom of the radiator of my 03 Forester 2.0X automatic without having to completely drain the system. I've seen the shop vac trick for the oil.. is there a way to do that with the cooling system as well?

Didn't add that junk when I changed it changed 8t at half the interval 6 ys vs 12 that SOA calls for.. just drained the rad. And filled then later that yr did it again, I will do it again this winter.

I've been noticing excessive amounts of debris between radiator and condenser two of these 2012 and 2013 the that need head gaskets because of overheating and blowing hose off top of radiator. I believe it's because the foam seals so good between radiator and condenser that debris cannot escape. Both had radiator 75 percent clogged with bugs and cattail like fuzz. My first fb engine head gasket job starts tomorrow. It has slight bubbling in radiator and an awful carbon smell in antifreeze.

I have a 2010 2.5 that on de celleration between 2600 and 3500 it sounds like the valved going dry ir rattling but if i touch the accelerator all goes What you think?

Entire job in 20 minutes on an automatic, but Subarus are so hard to work on. ;)

Mr. Subaru, I'm having serious problems with my 2020 Crosstrek rear differential. I can't get it apart because it's galvanically corroded (aluminum sundial in an iron housing + road salt). I've done heat, penetrant, hitting it for 10 days and it budged 1mm. But with all the hitting I'm destroying the sundial and I don't think it will come out without destroying it. I'm trying to put a Torq-locker in it, that's why I want to take it apart. Do you know if I can use a 5 bolt 4.44 in there? What about the axles for the 5 bolt, are they different from the 1 bolt in length or teeth? And if they are different, do you know if the 5 bolt axles will be able to plug into the rest of the components on the wheel side? I'm sorry this is so much to read, but I am incredibly frustrated with my Subaru and no one seems to know anything about this differential, not the dealer and not any independent Subaru shops I've called. I even had to make my own tool to fit on the sundial because no one sells a tool to take it apart. I'm hating this Subaru and I feel like the company has designed them to be not opened and just thrown away/dealer serviced only. Please help me if you feel like it

could you please tell me the name of the rectangular silver piece that is seat straigh towards the back away from where you working on. tks

i might have missed it, but what caused the piece to break on the radiator. was it just age/use. i've watched series and might have missed the cause.

Do you need the Subaru conditioner for FB25 engines?

Great video. List of tools??

No need to top off cvt fluid, and how many miles to head gasket failure?

What was that piece of equipment you used to refill the cooling system. How do you use it? What we're you looking at on that dial for and why?

Can I ask how you knew it was the radiator? My 2014 is overheating as well. I replaced both fans as they were burning up fuses. But it is still over heating. Any suggestions?

The problem is most likely air in the coolant system. When the upper radiator hose blew the first time, it allowed air in the system. Put it all back together and bleed the lines. Should be good to go after that.

How about refilling the transmission cooler

Robert, my 2011 OB Limited did the same thing. Are these plastic radiator tanks suspect at about 10-12 years? Is it advised to change these radiators out? I got lucky; I was idling in a parking lot and steam started pouring out from under the hood. Temperature gauge never moved. I got out and saw all the coolant then noticed the upper hose was off. I took off the hose, retrieved the broken plastic and was able to “MacGyver” the hose and clamp further onto the upper radiator outlet, add water and drive home.

What push pin removal tool is that?

MrSubaru, do you run a repair shop or just a really cool subaru hobby channel????

I had to repair my radiator I bought the parts from AutoZone. Would of been better to with OEM?

My 2012 OB 2.5L has 233K on it. Started heating up and bubbling coolent into overfow tank. Would that be worn head gaskets?

Me. Subaru could you please tell me on this model how many coolant temperature sensor there are

Hmmm, I've never seen refilling a cooling system with that setup before. What are the advantages that make it worth the cost of the equipment ? Just in case, what is the equipment list ?

Denso would be a great aftermarket radiator? Isn't it a Japanese company?

I watched this video on 8/31 and on 9/2 the exact radiator malfunction happened on my 05 Outback. My first thought was dammit I cursed myself watching how to do this repair. Oh well got to buy some new tools for the repair.

That was my problem with over heating I got mine for $75 from a junker. Actually 😂can’t same issue hose would come off. Replaced hoses , clamps and radiator.

What is the cost to rebuild a 2010 outback engine and add a radiator? Is it worth the cost?

2015 Subaru Legacy 2.5 Limited. 153,000 miles. Carfax has some decent service information. This car runs like it has 40,000 or 50,000 on it. Is there a way to find out in depth details? Thank you

Mr. Subaru. I need some electrical help. Clearance lights keep blowing fuse 14 on 2005 Subaru Outback

04 sti restoration series, then you doing pulls on the carolinas dirt roads yee haw

My lower radiator support is rusted through on my 2013, maybe it was unpainted from the factory.

Let's get it

I feel a little better about how much I struggle with those little plastic rivets now.

what happened with the radiator that you had to change it? and not just flushed it??

hi i was searching for cooling fans not working 2011 forester

What are the gloves that you wear? They look like a good balance of dexterity/durability/protection from fluids.

@mrsubaru1387 I have a 2011 Outback. I did this replacement too. I had the same exact issue with the radiator inlet pipe breaking off into upper radiator pipe. Now I have random issues with my cooling system. I replaced the upper radiator hose and put a new OEM radiator cap on it. I also put a new aisin thermostat in her. But I have a po128 code and I have random bubbles in my radiator reservoir tank. I block tested it three times to make sure it wasn’t a head gasket issue. It passed all three times. No smoke from the exhaust, oil is clean and so is the coolant. I’m about to replace the coolant temperature sensor today. If this doesn’t fix my issue what else could it be? Could it be a water pump starting to go out? Or maybe a tensioner on the timing belt not doing what it is supposed to? Please any advice would be much appreciated. I only get the bubbles in the radiator reservoir tank when at operating temperature after a longer drive. And the coolant will fluctuate way above the full line and then bubble over the top. Then randomly go back down and be fine. I also pressure tested the radiator. It passed the pressure test.

I am a bit surprised my EJ253 has a cast aluminum intake manifold while that one is plastic. However, my 253 has an oil cooler as well which I thought was unique to the manual/turbo models (my '06 Forester is an automatic) so who knows.

Hey I just change my water pump n radiator but still over heating. When it over heats the overflow fills up n doesn't go back to the radiator. What can cause this? I need help is it the thermostat? That would be the only thing I haven't changed. Any help would be greatly appreciated.

I smell coolant on my 2014 Forester at 65k miles. I'm wondering if my radiator is leaking slightly, and maybe that could be the cause. May have to do this repair.

i just had an issue with the PCV inlet that feeds the water pipe, it sits under the AC compressor on a 14 Forester FB25 i recommend that be replaced too for FB 25 engines my 253 forester 06 has never had any issues except a radiator replacement

Again? 🤔. It was coolant issues last time thou?

How much for the Genuine Subaru Radiator? I had to change mine on my 2011 Subaru Tribeca. The dealership wanted to charge me 750 dollars for it. I went aftermarket and changed it myself, which I found a pain in the rear end.

Ok. So I had the same issue as your brother. I went ahead and replaced the thermostat even though it was good, tested it. Replaced the radiator because I also had a broken barb. Checked the water pump for operation, good. (Replaced timing belt and pump, etc 7000 miles ago) Now, I used the same funnel for bleeding air but all of my fluid boiled! Took 20 minutes of running the engine before the thermostat wanted to open!?? Meanwhile I’ve got coolant boils over every where… lol. Why? After every drive, it smells like coolant. Oil looks good. Did the chemical test, no apparent signs of head gasket issues 🤷‍♂️ If you have a DM or email would love to discuss.

Pretty sure that conditioner is repacked k seal

The level of rust gleans a lack of maintenance. How is that still running?Pressure wash and regular replacement parts are key. Completely neglected

I would have run the stop leak with old radiator 1st, later fit new radiator. It is such a shame fitting a new radiator with a stop leak makes me sad for the new radiator but understand there is no time 😢 at the moment.

MrSubaru: Different topic I know, but: Have you ever done a video covering the grinding noise that some WRXs experience when decelerating in-gear from ~35mph? I've searched this topic here a few times, but come up short on good answers. The consensus by internet randoms seems to be that it's just an 'operating as designed' quirk, but I've never come across an explanation from anyone with verifiable bonafides. Even if that noise is 'operating as designed', it would sure be more comforting to know the exact cause of the noise. Mine is a 5-speed 2014. Best example I can find on RU-vid of the noise: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hC9kM_HRDBo.html

🤞🤞🤞

LOL Subaru radiator made in the USA and every domestic radiator is probably made in Mexico or elsewhere now. Funny how the world works.

Hey

I can't understand why they make radiators with plastic. The heat/cool cycles they must endure just can't last.

just swap the motor jk. this an example if aint broke go ahead and fix it. Aluminum radiator with silicon hoses DUH, RHALLY CAHR! waterpump/thermostat

Never saw anyone use that push pin puller tool you have. I can see where that would come in handy. Beats a screwdriver.
