I’m a little late to comments but I do work a Subaru dealer (8 years in the parts dept) and I will tell you that anytime we have to replace the coolant we still use those conditioners (right up to 2020 model years. It’s right there in the bulletins/service manuals. More info on the conditioner can be found in the MSDS. The main component of the stuff is phosphorous which also gives it the reddish color. That helps combat electrolysis in the long term, besides some “stop leak” ingredients. Just an extra FYI. Cheers.

I applied this conditioner when I did a full flush on my 2013 wrx, I forgot to shake it up and poured half of it in, when I saw two globs come out I stopped pouring it. I was able to suck a glob out but not the other. I’ll be fine right? I shook the rest of the bottle and poured the rest in with no globs.

I used this stuff at 130k miles a year ago and haven't had any problems with clogging or headgaskets on my 2011 Forester. The manual still recommends to use this conditioner. I noticed it actually prevented a leak on my old cracked radiator so I'm replacing that this weekend and adding this stuff again with new water pump and thermostat (did not replace it last time) now at 155k miles

From my personal experience with an EJ255 that cracked a top radiator tank and dumped most of the coolant on the Highway, this stuff is magic. Because my instrument cluster is red on black and it was a bright sunny day I did not see the temp gauge rise. It was not until the air-con started blowing hot instead of cold that I realised I had a problem. And because it was on a 4 lane highway , I had to drive for another 10 minutes before I could pull over. I opened the engine bay , and there was coolant everywhere. Got it transported to my local service centre. Three days later I got the call to pick it up. I live in a regional area in Australia so 3 days is pretty good. The mechanic said to keep and eye on the coolant level , as it could have internal damage. The Forester was running OK, but was consuming a fair bit of coolant. I remembered seeing this video , so I bought the full size bottle of Holts Radweld, ,sucked out 250ml of coolant and poured in the Radweld. That was 2019 and it has not consumed any coolant since.

Love your channel. Pretty much every tech at our dealer watches you. Don't know if you knew this, but in the beginning the bottle didn't say HOLTS at the bottom. They didn't want people to know exactly what it was. I remember when they first put it out. We came up with different theories from...neutralizing minerals and deposits in tap water that would eat the metal head gaskets to straight up stop leak. You are right though, it never really worked. Oh, FYI, I used to stick them in a cheap little paint shaker to break up that "ginger root" solidified crap. You could shake those damned things til your arm fell off and there would still be chunks. Had that crap clog bobble valve on the thermostats before too.

Glad I found this video. Getting ready to change son’s coolant in a 16 Forester & was going to add this. Now I know it’s only for 99-02’s. Thanks! I did buy Zerex Asian blue coolant to use.

I had success in dramtically slowing a coolant leak. I used Subaru Cooling Conditioner in my 2006 Outback. Had a coolant leak that testing showed was due to a head gasket leak. Added 2 bottles and after about 2 weeks the rate of leaking was significantly slowed. I went from adding coolant every 2-3 days to not having to add coolant for about 3 weeks.

My 1999 Outback had a blown head gasket and it cost $3000 to be repaired and was never the same again, I gave it to a junk yard when it would only go 40 mph on the freeway. The service department GAVE me several bottles of that to help me before I had the repairs done. Obviously, it didn’t work. I have had 6 Subaru’s over 22 years and that was a bad apple 🍏 but overall I love and continue to roll with Subaru’s in retirement. 02 LL BEAN OUTBACK 08 Tribeca LTD, 08 LL BEAN FORESTER current lineup.

I'm always skeptical of anything with the word "conditioner" for vehicles. It just immediately makes me think it's going to make my metal and plastic bits soft, pliable, and voluminous.

This is the best explanation I’ve seen on this topic. Of course so much of it is word-of-mouth there’s no real testing that I can find. In 2010 I purchased a 2004 STI and had a local Subaru tech who just returned from Japan to study STI do a full inspection. Not only did himself but the rest of the Subaru dealership told me not to use that in the EJ257 due to clogged decks . They showed me a picture of a block that had that brownish crap all up in the coolant passages of the decks. I never used it since and have flushed and drained almost 5 times since then and I’m still on the stock head gasket and my coolant is Bright Green.

I don’t like to do my own repairs; my financial situation forces me to do my own repairs lol 😂😂 Thanks for the great videos! You’ve helped me out a lot!

Can you make a video about Subaru Carbon Clean next. A friend of mine is using it in his '15 XT to prevent carbon buildup.

I have a 2003 Subaru Legacy L wagon , I had a water pump go bad so I did a whole timing belt pulleys and tensioner ,water pump, thermostat replacement , it probably had a leaking head gasket at that time but I didn't know so after I fixed the water pump and stuff I refilled the coolant and started driving it within a couple days car was still losing coolant and getting warm , I could run the heat and keep temp in the normal range, so I figured I had a blown head gasket and was gonna cost 1500 to put gaskets and seals on it. But I heard about this Subaru coolant conditioner and so I figured I'd give it a try , I used 1 bottle and now it is not leaking any coolant and my temps are actually cooler than normal with no heat on at all I can run AC so this stuff is magic , yes I understand it's just a temporary fix for now but its awesome and it could really help someone that dont have the money to fix it or want to put that much money into a older car

I had it put in when I got the letter. No issues. Just had to replace the radiator due to the plastic cracking. I took the plastic off and at 19 years the radiator inside looked like new. Not a spec of corrosion. And no leaks. Now I will after saying that.

Thanks as always Mr. Subaru!

Wrx and sti's or any Turbo version of these engines use multilayered steel headgaskets and do not suffer from these issues nearly as much as the naturally aspirated engines. I have 189k on a all original wrx turbo 2.5 with no external leak what so ever from the headgaskets. I am however about to try this stuff on a different car that's leaking coolant into the combusion chambers after its warmed up and shut off. Nothing to lose so we will see.

Ginger root is organic. Healthy for the engine and for the driver. I'm all for it. lol

I have not used it in any of my 2nd gen wagons with the EJ25* after I replaced the original head gaskets with the multi-layer steel gaskets (5 of them so far). All but one had the oil leak but no compromised cylinder sealing areas, or coolant leaks. No problems here so far. I do buy the Subaru coolant.

That’s funny! I had a 2004 forester. I traded it at 14000 for a Jeep in 2005. I kept smelling coolant inside and outside. The dealer couldn’t find a leak.

Look up the MSDS information on these products, that should further confirm what's in the bottles. Very informative, thank you!

Very informative video, especially the comparison vs holts. FA20's also have the conditioner listed in the service manual, but doesn't specifically call out it's necessary.

Radweld has been around for years in the UK. It's a sort term fix, doesn't work on any significant size leaks.

losing coolant, figured it was an external head gasket leaking, pretty bad. Tried a bottle of this stuff and well, so far, so good. seems to be working. I have 90,000 0n the 08 forester. Had the coolant changed at 30,000, I assume, they did not add this product and I was not aware Subaru recommended it on my engine. Due for another coolant change now, I'll add another bottle.

Did a coolant change today for the first time on my 04 LGT. Wish I watched this first. I ended up putting some in and now wish that I didn't.

Bought a 2009 Impreza hatch 2.5i last spring with 87000km. Had the dealer give it an inspection when they completed the takata airbag and brake line corrosion recall. They informed me that my driver side head gasket was starting to go. Bought some Blue Devil thinking it would prolong the necessity to do the job; big mistake, had to replace my entire cooling system minus the water pump as it clogged up the rad, thermostat and heater core. Replaced all parts in question and was stupid enough to use the Subaru coolant conditioner; it gummed up my brand new heater core. I was lucky enough that a few reverse flushes with boiling water cleared it up, but I certainly won't be using any kind of sealer again. Bottom line is if a gasket is breached, replace it!

So if I'm gauging this right, basically ANY Subaru vehicle that's still on the road or has been sold in recent years is going to need this product at some point. I'm at a loss to explain why SOA wouldn't just throw it into the maintenance schedule so that there could be no doubt that the conditioner, if not regular HG inspection from ~80K forward, is required.

News View , To be honest what we found when we were replacing head gaskets is that the torque procedure was one of the main problems, the service manual required the outer head bolts to be tighter than the center bolts in the head. When we torqued all of the head bolts to the same spec we rarely ever saw a comeback. And to be honest that stuff is made primarily to coagulate any potential leaks in a head gasket and as a side effect it will gather up in a radiator like a blood clot. I would avoid using it and stick to draining and refilling the coolant at its recommended interval. If you do have to replace your head gaskets, make sure you use new bolts and torque all of the bolts evenly.

I have an 11 Forester and found oil in the radiator and overflow. Is this a problem with the head gasket or something else? Is it worth to try a sealer, if it is?

Toyota has had 'stop leak' in their 'factory' radiator coolant additive for YEARS. When there's a pin-hole lead (which... their raidiator's frequently display), the 'stuff' leaks out and cristalizes (yellow-white) at the leak site... and tends to stop it. Their coolant also of course has a 'water pump lubricant' in it too. I think its a amphoteric 'buffer' solution, to keep things from going too acid. (Toyota coolant is good stuff, I use it in my Beemer). BMW stuff is good too, but not 'better' than Toyota's.

I agree think it was done so owners become liable for the vehicle repair instead of Subaru being required to do all the repairs

I believe it's a split year. Do I need to run this conditioner in the 1996, 1997 Subaru legacy 2.5 gt? I believe it is the first generation 2.5l

Hi Mr. Subaru do I have flush the coolant and remove the thermostat before adding the conditioner?

The service manual for my 2018 Legacy 3.6R says to put this stuff in.

I remember the early 2000s - 'head gasket blower' quick fix

shouldn't it "harden and swell" in the open air?

Mr Subaru,will the rear diff and hub bearings from a 1998 Forester fit a 1998 out back legacy?

Yes and no. It'll bolt in, but the gear ratio is wrong.

So should I get some I have a 2014 subaru legacy 2.5i plus I have no more warranty I have to do a flash it just turn 100,000mile

So how much more common were heater core replacements after they introduced this?

I've never replaced a bad heater core in a Subaru. Never seen a bad one either.

14:00 LOOK LIKE COOKIE. SMELL LIKE COOKIE. MUST BE COOKIE! NOM NOM NOM!!!🤣🤣🤘🚗

So dose my 18 outback have a 8 yr 100,000 mi. warranty on head gaskets ?

Is it ok to add this to a 2008 Subaru Outback with EZ30R?

Never got the letter for my 2003 Forester which ended up with leaking head gaskets. 2003 engine is the same engine as the 2002.

Was basically an issue until 2010.

I bought my Impreza in 05... never seen that letter or that bottle. I only run super coolant blue in my engine.

Hello Mr. Subar8u please help me?? Am replacing all coolant hoses in my 2013 Subie Crosstrek Limited with approx 74,000 miles. Do I HAVE to put that Subaru Cooling System Conditioner in my car?? Thank you in advance. FWIW NEVER had any leaks whatsoever anywhere.

My outback blew both head gaskets, I replaced both myself, Subaru will never admit they used crap head gaskets in the first place, anywhere from a 150kms and up they will eventually blow...

Will it work on heater core?

my subaru dealer told me they dont use this anymore. And are only selling whats left in stock.

Probably because the newer gaskets don't have the same issue with the coating etc.
