1 Month and 100’s of miles AFTER Does Stop Leak really Work? Testing the Top Rated Coolant leak Fix!

Vicky the Van springs a leak?! A year ago I discover a pretty major coolant leak and old Vicky the 2000 Dodge Grand Caravan around the timeing chain cover, in this Block Seal Liquid Copper Intake and Radiator Stop Leak review.
My experience in the Caravan same vehicle as the Chrysler town and country and Plymouth voyager mini vans. Unable to remove the timing chain cover I reverted to extremely desperate measures as a mechanic. 😂🔧

I want to buy a beer for the man that invented that. It saved my butt.

Me too still working to this day.

[@makemoneyonline8793]

I used the same bars leak in the video and used their products for years. I never used the product for head gaskets or other major repairs, The times I used the product was only for a leaking radiator and it works! Follow the directions for best results. I only used half of the product for my situation to get by a few days until I purchased a new radiator.

[@RussShawTV]

I’m glad that worked for you. And kudos on buying a new radiator because that’s the best thing to do.

[@mrbizzarro]

Yo russ! Great video! It's always good to know what you can do in an emergency. Bars leaks is definitely the best you can get. I'm curious to see how it works as the seasons change.....c ya!

[@RussShawTV]

Me too once Summer comes and I’m running AC most of the time 😬😁🤘🎸

[@johnbowen8917]

I hate it.. but it worked for me.. Just failed after 3 years of daily driving. Going to dose it again and keep going until used car prices come back to normal.

[@RussShawTV]

I would recommend flushing the coolant system after 3 years then reapplying as to not clog up the cooling system 👍

[@RB-er6gu]

I used the exact same stuff it works great had a heater core. Leak

[@misssusan8000]

Good stuff!!!

[@tommiblackson118]

I have a 2007 Chrysler Pacifica yes my radiator is crazy hard to get to they have to move the entire engine to get to it. I've even had my fan done twice. This stop leak will definitely help me with saving money. 🙏🏽🙏🏽🤞🏽🤞🏽 Thank you for the update throughout the video. I was sold after the permanent remark. I watched a few videos and yours is the best one I've seen. I'm 🏃🏽‍♀️ to get it now

[@Aeroshogun]

Same here, I drive the exact same car and I have a coolant leak too. I was hesitant to put this in the car but my mechanic recommended it and you confirm that it works in the same car I have. Thanks brotha/sista!

[@tommiblackson118]

Good thing I found this video I was about to get "stop leak 2x " or stop leak heavy duty SMH I didn't know they had a permanent one 😮😮

[@basicforge]

I've had a bunch of cars over time, and it seems like I'm always running into problems with the coolant system. So, when my Toyota Sienna started leaking from the radiator, I decided to try something new and used a Bars Leaks radiator sealant. I poured about half of the bottle into the coolant tank and then drove around my block. But then, the van started to get really hot, too fast. I went back home, waited for the engine to cool down, and checked under the coolant system cap. There was a big chunk of the sealant stuck there-it looked like a bunch of tiny metal bits mixed into a jelly. I just grabbed it and pulled it out. After that, I drove around again, and this time, the van didn't overheat, and even better, the leak stopped. It made me think, maybe I should have shaken the bottle more or used something to catch the big chunks before they could get into the car. Would I use it again? Maybe, since it actually worked in the end.

[@RussShawTV]

Yeah, I think driving it around the block is not enough, you gotta get that engine nice and hot drive around for a while or just let it idle for like 45 minutes. Driving around for 20 minutes is best though because the engine revving up and coming back down will swell that liquid copper around in there better. I’m glad it worked out for you. as mechanic though, I would encourage you to replace the radiator.

[@basicforge]

@@RussShawTV Sure, in retrospect I should have replaced the radiator, but it lasted for years after that application. I wasn't able to drive it for more than a few minutes at first because it was overheating in my case.

[@mickmaszt4485]

I've been told for many MANY years additives are bad for your engine blah blah blah but my leak was EXACTLY as yours on my 1998 caravan. Was quoted $1900 for the fix It cost me $900 to purchase the van so there was no way I was spending that! Saw your video and said what the hell what do I have to lose? Day 2 and this stuff is working!!!!!!! My leak was a constant drip drip drip. You can see it dripping from under the car puddles of water and antifreeze, now? Not a drip! Your video saved me thousands of dollars and a new van (for now) not to mention I'm also in Seattle 😂 same van same problem. Same city I said. Let me see what happens and I will tell you man. This stuff works. Thank you thank you thank you for your video!!! I would have never tried it without watching your video first!!!!!

[@RussShawTV]

That’s awesome. I’m glad it’s working out for you! Mine is still going strong even in the heat we’ve had lately. It still loses a little coolant but more in the overflow tank. I’m only adding coolant to that every few months or so. Just went over 170k and still going!

[@mickmaszt4485]

@@RussShawTV lol @ 170k ours sits at 273k😂. The stop leak did not eliminate an oil leak that was pre-existing however, it did reduce the oil leak also 👍👍 As you said in Seattle today is warm. We drove it and no coolant leak. Can't believe it man. And yes I subscribe to your channel and I never subscribed to much of anything on KZbin lol. Thanks again!!

[@CHEAPROLLIN]

Does it have exhaust gases in coolant?​@@RussShawTV

[@RussShawTV]

Exhaust in the coolant? You could have oil in the coolant. If you run your engine too hot, for too long, you will blow a head gasket that can/will happen. if you have exhaust in your coolant, it will keep blowing out hoses. This is what happens when you get compression coming up through your cooling system. Then you’re gonna have to replace the head gasket. Not sure what you mean by “exhaust in coolant” 🤔

[@CHEAPROLLIN]

@@RussShawTV I mean combustion gases in radiator

[@antdate5082]

I think K-Seal is the best stop leak but the bars leaks worked.

[@tommiblackson118]

I hope I can pour it in and let it sit. I hope you can pour it in with the coolant because I'm on empty again. It's expensive to keep buying everyday.

[@cramcrams7741]

Steel Seal the one but must be ordered direct from the company and is super expensive.

[@DiamondMounter]

Ive already used head gasket sealer in my car is there a reason why I shouldnt use this to fix a leaky radiator ?

[@RussShawTV]

Depends on what kind of radiator. A lot of times the radiator has plastic tanks on the sides. The stop leak, odds are not going to adhere to plastic. Even if it does, the plastic is going to expand and contract based on temperature. If I were you, I would replace the radiator.

[@arnoldlao8398]

[@VladRonin]

I have Honda CRV 2007. Have a Heat Hose Leak ... I can fix that leaks by Block Seal Liquid Copper Intake and Radiator Stop Leak ??? I used Reslone, but still dripping . Thank You !!!!!

[@RussShawTV]

If you have a hose leak, you have to replace the hose. These products are not going to fix a leak on a rubber hose. And pouring all that gunk in your engine is not good for your cooling system. Anytime you have a hose that’s leaking. The hose needs to be replaced ASAP. Good luck I wish you the best 😁✌️

[@RussShawTV]

Sometimes you can get away with cutting the hose where the leak erupted. Cutting a ring all the way around and then putting the hose clamp over it as a quick fix. I’ve done that before on multiple occasions.

[@VladRonin]

I have metalhose. Not rubber. It's a stupid Honda designers...

[@wallabing]

After the leak is plugged/stopped, do you have to drain the entire coolant and replace with fresh new one?

[@RussShawTV]

🤔 a lot of that depends on what kind of car you have put that stuff into. There’s a lot of disclaimers in the video, but if you have a Dodge Caravan, I would recommend leaving it in and not flushing it out of your cooling system. It may (like in my vehicle) affect your heater core, but if you have a severe leak like I did, it will continue to seal it if it comes loose and starts leaking again. If it’s a radiator, that’s leaking I would suggest replacing the radiator. And especially if you’re your water pump that’s leaking replace the water pump. In those cases I would suggest changing the fluid. 💧 I hope that helps. Thanks for commenting and subscribing to the channel. 😁👍🔧

[@VladRonin]

Thanks for answering. Thas hose is metal, not rubber. But I think it's a better replace hose, but very badly located that part. Poor made from Honda....

[@RussShawTV]

It may have a shroud around the hose, but the hoses are rubber. Hondas are very reliable vehicle, but they like all other vehicles do break down overtime. Take care of your vehicle. It will take care of you. I hope all that helps. 👍😁

[@Imadethistocomment13]

I just want to know how this does not block or create a block inside the radiator

[@RussShawTV]

Thanks for commenting! Good question! Added a new video about this vehicle recently. I think it’s in the end screen of this video 🤔 a year later after adding the stop leak. Anyhow, it is a great question! And that’s part of the risk of adding these kinds of “fixes” to your radiator. Sometimes the fact that the radiator is clogged is the reason someone’s having overheating problems. It’s why I mentioned in the video you need to know where the leak is coming from. And if you don’t have a leak, there is no need to add this product to your radiator. If you don’t know where the leak is coming from from you need to find it. As a mechanic if the radiator is leaking, I would advise replacing the radiator. Adding this kind of stop leak is a quick fix until you can afford or have time to replace the radiator, but radiators for these vehicles aren’t that expensive. If you do have a leak as I said, it is risky and as I said, in the new video, my heater core isn’t working as well as it used to before the additive. For me, this is worth the risk as taking the timing chain cover off and getting broken off bolts out from the engine block was not going to be mechanically, a.k.a. financially possible. Also, I’ve been very happy with the product not needing to get another work donkey still driving this one, but it does get chilly when the temperature outside drops below freezing.

[@Imadethistocomment13]

@@RussShawTV thank you so much for explaining and I really appreciate the time you took

[@Mister_CVC]

How was the air? My air is blowing cold on idle but then blows hot when accelerating. I changed radiator cap, changed thermostat, and topped off with coolant. Any suggestions?

[@RussShawTV]

Video coming soon 😁🔧❄️

[@Mister_CVC]

@RussShawTV Now I'm not getting any heat whatsoever. I'm thinking it's the heater core but I don't have water to use because it's freezing here to flush it out and the pipes are shut off. I don't believe it is the water pump, either. I haven't had the chance to flush the radiator because blue devil you should not use when below 32°F and it is below that. I am going to change the lower radiator hose but want to do all of that in one fell swoop. Until then I'm car less and not feeling very macho. 💔

[@Mister_CVC]

@@RussShawTV Thank you. 🤠

[@RussShawTV]

@@Mister_CVC you should always use coolant at 1/2 and 1/2 concentrated. 🤔 is the radiator still full?

[@Mister_CVC]

@RussShawTV Well for some reason, the radiator keeps losing coolant, thus, making me believe that there is a leak. I have to keep adding coolant and overflow tank is not pushing fluid in. Level stays the same. Any thoughts? Definitely a clog and just something is not right.

[@theluckyman74]

I bought both liquid alumin and the Copper version so you are using the copper version?

[@RussShawTV]

Yes, but may I ask what you’re using it on? My fear with this video is people will try to use it to fix a water pump or something which I will not do long-term.

[@sabinovazquez2235]

Can I Pore it on the coolant reservoir?

[@sabinovazquez2235]

And my truck starts leaking after I park it

[@RussShawTV]

No, you need to find out where the leak is coming from. If it’s the water pump, you should replace the water pump for example

[@user-cc4px1jg1y]

Is that a cast iron engine or aluminum

[@RussShawTV]

It would be a steel engine block. It was leaking from the timing chain cover gasket.

The stuff worked for me as wel last week. I had a small leak in a 20 year old Jaguar S-Type radiator. I poured in the stop leak (the liquid aluminum version, not liquid copper)I started the engine and started recording the leak. Right about 19 seconds in here you can see it go to work. kzbin.info/www/bejne/n4GkXnWYerZsjpo

[@RussShawTV]

I would be curious how it works out for you. Usually the stop leak in the long run doesn’t adhere well to plastic, because plastic expands and contracts differently, then steel or aluminum. Keep us posted 😎👍

so it won't stop a leak in the water pump?, 2002 Ford econoline v6 E 150 van@@RussShawTV

[@socorrohernandez8743]

I ask my mechanic about this and he said it doesn't work.

[@RussShawTV]

It depends on the application. For this application, it was a gasket in between two metal pieces so I believe that’s why it’s holding. It’s still holding to this day. But I would agree if it’s a leak in your radiator as most radiators today are plastic. Same with heater core. The liquid copper is good for ceiling leaks where the materials surrounding the laceration or a hole is metal. Plastic will expand and contract depending on the heat. If you have a hole in the radiator, it’s just going to get worse. I would agree that this application wouldn’t work for a hole in the radiator.

[@RussShawTV]

As a mechanic myself, we are taught that this stuff doesn’t work. And most of the time it doesn’t but technology changes over time. But yeah if it’s your radiator it’s not hard to replace the radiator. And they do go out. On my channel the caravan I had with 430k I replace the radiator in that van three times.

[@tommiblackson118]

Your mechanic probably just wanted you to spend money on a new one so he can get paid to put it in. My mechanic told me that there's no glue or cylinder I can put on it. I was about to buy a whole new radiator. And this is my second one. 😮 I'm going to try this definitely

[@RussShawTV]

@@tommiblackson118 actually I am a mechanic 😁🔧. My or may not work for a radiator. Depends on if your radiator has plastic tanks on the sides. The copper doesn’t adhere well to plastic. That and the plastic tanks expand and contract over time causing the stop leaks to fail.
