This Destroyed My Car’s Engine, Here’s Why

This Destroyed My Car’s Engine, Here’s Why

rev up your engines today I’m going to
tell you the truth about radiator sealers for use in your car do they
really work throughout the history of cars people have attempted to fix them
by adding some type of sealer an Australian mechanic showed me years ago
what they did in the outback they’re kind of in the middle of nowhere it I
see they got a little radiator leak they go to the first store they could stop it
and they would buy some course pepper and they poured the pepper in the
radiator and it actually could stop the leaks in the old metal radiators and I
remember years ago in Houston I used to buy a great radiator sealer that was
made in Oklahoma and it said warning contains organic material well they
weren’t joking because the guys at the old Charlie’s hi/low auto parts store
they sold the stuff and he said you’re not kidding one time a rat got in and it
ate a whole bunch of the sealer they didn’t find any dead rat so I guess the rat
liked the organic material and ate it hopefully it didn’t seal up the back but
I don’t advise you to experiment with organic materials like pepper in your
radiator if your radiator split wide open has a hole especially with modern
plastic radiators if this plastic is really old and brittle even if a seal is
put in fixes one crack hey the whole thing’s cracking there that general
start leaking it’s not safe to drive it that way but often they leak on the
crimps cuz even though they call them plastic radiators they’re actually
plastic and aluminum the cooling fins are all made out of aluminum and if it’s
leaked in there the sealer can often get between the aluminum and the plastic
where it’s crimped and stop the leak entirely but how do you know which one
to try why I’ve been fixing cars for the last 52 years and nobody’s telling me to
hock their products nobody’s paying me to tell you this is better than that
it’s just experience ages ago when I was a young mechanic we used the same
company bars leak they were called pelletized ones and they had a liquid
with pellets supporting radiator didn’t work quite well but you could say this
is now liquid aluminum it’s not pelletized it’s liquid aluminum as
radiators a technology change the sealers change tools hey it’s pretty
much the best one out there for fixing leaks in your radiator big advantage as
you can see here works with all kinds of antifreeze or pure water so you can use
it with anything the problem with a lot of the older sealers are if you use them
with the modern coolant the old coolant they will coagulate and clog up
everything your heater core make your engine overheat worse than it was in the
first place heck that’s one of the reasons they make these videos to show
people what they have to use with modern technology so always watching my newest
videos because that has the newest information you could possibly get out
of me yeah I’ve been doing it for 52 years but some of the old stuff that
used to work doesn’t work and there’s newer stuff hey it actually does work
templates to use when the engine is cool you just like the radiator cap off and
pour the stuff in now I don’t need to pour it in here cuz it’s not leaking but
that’s all you have to do with this stuff but let me give you one big
warning yes it works on all kinds of cool under pure water it’s not gonna
clog things up that way but never ever use any type of sealer this one included
if you’ve got dirty rusty corroded coolant in your vehicle the first thing
you want to do is flush out your cooling system I got a whole video on that then
put the sealer in the coolant end it’s the same if say you got a leaking rear
main seal on your engine you don’t want to pull the transmission off to replace
that engine rear main seal for the engine oil if that’s leaking the first
thing you would do would be change the oil and filter then you put a good seal
around and for that I use this at 205 reseal it’s often hard to find say in
Chicago but Amazon sells it so anybody can buy it if they really want to get
hold it but you want to put it in clean oil not dirty because the clean oil has
less friction this is gonna work longer and since it’s clean oil you’re gonna
leave it in longer for the whole cycle so let’s say you got a small radiator
leak as long as you’re cool once clean enough you just pour this stuff in and
drive and you’re leaving it you don’t have to take it out it mixes perfectly fine
with it I’ve been using this stuff for years and
I don’t have any problems with it if you have a physical leak in your radiator
this can often seal it for years I’ve had customers I put the stuff in three
years later it’s still not leaking well of course when it’s time to change your
cooling again then you’d have to add another can with a new coolant but hey
if it lasted that long man you’re getting your money’s worth but let’s say
you got a head gasket leak the worst kind where the head gasket on your
engine either burning coolant and you get white smoke coming out of the
tailpipe or you see coolant leak in between the head and the block if you
see coolant way down here with a head bolts to the block down here under here
or on the other side what you really can’t see much of here but you’d have to
look on it with a flashlight that means that the head gasket is leaking between
the head of the engine and the block how many cars today it’s gonna cost you well
over a thousand dollars some of them four or five grand to replace it it’s a
very expensive repair and for that you need a special sealer this is much more
complicated if you want to do it right the other stuff you just pour it in
drive it or where you go but head gaskets it’s a completely different game
because the radiator pressure leaking is like 15 pounds per square inch
the head gasket seals the engine compression when of gasoline fires of
the spark plugs to the outside world or to the cooling system and that can be
well over 1,500 pounds per square inch when the spark looks fun so it’s a lot
harder to seal now I’ve been using the seal up stuff for decades it used to be
made up Street in Conroe Texas but they got bought out by a company called Blue
Magic so now it’s blue magic seal up used to be car go seal up but it’s
the same stuff and what the main ingredient is as you can see here
contains sodium silicate known as liquid glass now sodium silicate is a compound
that really can seal leaks it’s almost instantaneous I’ve had cars where I put
this stuff in the correct way once I started out engine within five
minutes the white smoke would stop coming out of the tailpipe and it would
stop that leak and a head gasket but it’s more complicated don’t listen to
anyone elses directions because it’s a lot of baloney anything that has sodium
silicate in it the first thing you have to do is flush all of the cool
out of your engine and remove the thermostat this stuff has to be used
with pure water but if you do have a blown head gasket realize it might cost
you thousands to fix it so it’s worth spending a few hours flushing all out
then putting just this is and pure water you can let the car sit idle for
half an hour then shut it off cool down for half an hour start it up you can do
that five or six times because the sodium silicate only works when it gets
about about 105 degrees Celsius it’s got to be warm inside for it to work if it
doesn’t get hot enough it won’t work it’s got to get hard enough to make the
bond and seal it up and in extreme cases let’s say the number three is really
blown bad you would remove the number three spark plug so that when it’s
running in a runoff but it won’t build up all the pressure and allow this to
seal that cylinder there’s a lot of tricks to stuff like this it’s not as
simple but if it works you’re gonna be really happy
I have personally used to seal up in cars I remember a Honda accord I use it
in three years later the lady was still driving the car but if you do any
research on this stuff you’re gonna say some people that absolutely hate using
any product that says sodium silicate in it because they say I put the stuff in
and my engine blew I had to get another engine well first your engine ones going
out anyways but it can actually ruin certain engines so this is what you have
to check before you use this stuff get out your engine dipstick make sure that
the oil is full not really over full because if it’s over full that generally
means water’s in it or if it’s really full of water this will be all foamy and
you’ll see water bubbles on you’ll know you now have radiator coolant inside
your engine oil now if you do have radiator fluid mixing with your engine
oil that means that you put the sodium silicate in your radiator it’s gonna get
some of it into your engine oil which you never want to do because sodium
silicate works super fast like I said sometimes within five minutes they stop
smoking and I use it in warfare guys used to use sodium silicate to destroy
engines let’s say you’re abandoning your tank they would jet the pour like a
gallon of the sodium silicate you to the engine oil and when the engine
started up that silicate locks the bearings up and the engines just frozen
and won’t work anymore so a few have coolant in your engine oil don’t try
using this or any sealer that says contain sodium silicate there’s a lot of
them that use the same process but there’s some kind of law in the United
States that says caution contains sodium silicate that’s a warning label on these
now if you drank the stuff it could kill you it’s probably one of the reasons it
says warning but the main warning is for your engine you never want any of the
sodium silicate to get mixed with your engine oil because if you do yes it can
destroy your engine and that’s why some guys try this stuff they don’t check
they got coolant going into their engine oil when they put this in it can destroy
your entire engine there’s no arguing that but thankfully head gasket can blow
in many ways often they blow between the head gasket and the cooling system or
the cooling system on the outside of the engine where you see the coolant leaking
outside and the oil galleys inside the head those seals are still working so in that
case yeah you can use the sealer won’t hurt
anything but if you’re getting coolant water into your engine oil don’t
ever use any of these sealers that say contain sodium silicate cause then
you’re taking a big gamble your engine might lock up in that case you’re either
gonna bite the bullet and have your engine taken apart and a new head gasket
and all the other gaskets that come off when you take it apart replace don’t try
to use this when you get coolant in your engine oil
I mean marking has changes over the ages this is their new bottle but their old
bottle it used to say for professional use only because I only wanted pros
using it who aren’t gonna pour it in one and lock up the engine we’re a public
guy might just buy this to sell great I’ll pour it right in and they don’t
know that the head gasket is leaking oil and water mixing in the engine and then
the sodium silicate in here it can just make your engine lock up the bearings
will just lock right up if they get sodium silicate on because the sodium
silicate sealer hey it can be a genie in a bottle but it can also be a bad
that doesn’t give you your wishes but gives you your worst enemy a blown
engine if you pour it in when the water is leaking in the engine oil so now you
know when used correctly different types of sealers can be used to fix different
types of leaks in your engine’s cooling system but do use them in a correct
manner and since this is mechanic Monday I’ll be giving away a bunch of these
seal ups to have a chance to win place a clean non offensive comment and YouTube
comments below and a winner will be chosen randomly by computer to attempt
to seal a blown head gasket for about ten dollars instead of a few thousand, so

ring that Bell

  2. I used to carry pepper in my car back in the early 80’s to seal my radiator until I had it replaced. It worked rather well.

  3. in california the head gasket stuff will still make you fail a smog check. so you cant use your car on the road cuz you can't register it if you fail the test.

  4. if it is leaking, just replace parts, dont use sealer, it will clogg all the passage ways, it isnt smart, it just closes all those tiny holes in the radiator and causes total engine failure cuz it will over heat cuz the holes are all sealed up. its like throwing sand in ur radiator, will it fix it? no. u just gotta find the leak and replace the parts, do it right or u gonna buy a new car

  5. Scotty, would you recommend a 2005 Nissan Titan or a 2001 Nissan Frontier, one of these will be my new and first pickup
