When This Happens, Your Car is Screwed

When This Happens, Your Car is Screwed


rev up your engines this overheating Nissan the engine is overheating customer brought
it over here after taking it to other
mechanics you never know what
anybody’s actually done they told her
this that and everything else but you
got to start out with the basics now number one this is a brand new radiator she
told me they paid to put a radiator on
this but it didn’t solve the
problem and right away I can see the
cooling fins and there’s no coolant in
them I told her I’ll probably use the
thermostat now
well it’s low on coolant a thermostat opens and closes but generally isn’t going to make it
low on coolant so I really kind of
wonder about that I notice the check
engine light is on so I’m gonna test that
first plug in a scan tool turn the key
on and see what it says it’s reading
codes
got a whole bunch of codes let’s see
what it says the engines running too hot
knock sensor driver airbag module now
knock sensors on these v6 Nissan’s go
bad all the time at the royal pain to
change you got to take off the intake
manifold and that general isn’t gonna
make an engine overheat the only code
they’d ever do with the engine
overheating is the one that says the
engines overheating we already know that so I’m gonna do a block leak check on
this often some fool will change the
radiator when actually the engine is the
problem and fixing the radiator
replacing it with a new one like this
doesn’t fix anything if the engine is
blowing the head gas a simple test we
get the test fluid and start the car
put the test tube over the radiator
and take off top it never want to pull off
that’s a job getting that off and pour it in and stick the top back on
and do some suction
now if this dark blue liquid turns
collard green a bright yellow means that
gas go to the engines leakage and as you
can see it’s turning yellow
quite a difference in color now this
doesn’t surprise me cuz the engine has
two hundred and sixty six thousand seven
hundred and ninety-one miles on it and
as I sit here and rev it up a little comes
down I can feel it rumbling it just
doesn’t feel right to begin with it cost
a fortune to do a head gasket job and
who knows a lot of corrosion may be the
heads corrosion inside it’s really not
worth the money on this thing to take
the engine apart and attempt to fix it
mechanically now the customers decided
to let me remove the thermostat and
tried some sealer because if you put
sealer in with the thermostat a lot to
make it stick shut then it will really
overheat so we’re gonna remove the
thermostat put in some sealer and pray
at last go take the air filter out of
the way and we’ll look down here the
thermostat is right inside here we just
take the bolts off and we’ll get it out
so we on both the thermostat and there
it is we’ll just cut the old thermostat
out so it can’t get stuck then we’ll
pull this 3m sealer all over
and stick the gasket over now I use this
3m weather stripping gasket
sealant for two reasons one I don’t want
it slipping when I put it in there’s no
working room so I’m gonna let it sit for
half an hour while it dries then I’m
gonna put sealer on the outside and
bolt the whole thing in that way it’ll
be sealed and not leaked I’ve had tons of
them in the past leak if I didn’t use
sealer to hold it in place they’re going
cockeyed you get a leak and then you’d
be screaming mad when you filled it up
then we put the thermostat housing
back in get all the three bolts in and
and put the hose back on then slide
the clamp on using pliers then clamps on
nice and tight then want that phone we
don’t want any air leaks that hopefully
comes a miracle in a can the bars head
gasket sealer which is part a whole can
then pour the coolant in it came out
then we start it up and pray the sealer
works
now what you want to do now is let it idle about half an hour shut it off
the sealer can do its thing let it sit
for a couple hours and then basically
drive it around and see what happens
well so far it’s held up only times
gonna tell on that but now you know what
to do if your engine is overheating even
though you’ve already replaced the
radiator and it didn’t fix the problem
in the first place, so if you never want

  1. I had a friend who thought it made sense to keep driving on an overheating engine because no steam was coming out of the engine! LOL! He then ended up paying for a new head.

  2. Scott, what is your opinion about a 2007 Toyota Highlander with 160,000 miles? Is it reliable? It has a little bit of rust underneath the car but nothing is torn up nor deteriorated. No clicking noises, nor caliper rust.

  3. Off topic but maybe someone can help me. My 2001 Camry loses power everytime I turn the key on. When I wait a few minutes the power is back and my dash lights are on but the car loses power again when I turn the key back to the on position. I'm thinking that maybe I need a new starter. Can anyone help me?

  4. How much is a used engine for one though? For my moms v6 Tacoma that just hit 200k I'm gonna buy a used replacement engine and tranny since they're super cheap.

  5. Pathfinder and Xterra were known for mixing transmission fluid and coolant together. Bad engineering on Nissan's behalf

  6. A blown head gasket sucks. You’re right you usually have to junk the car especially with that many miles

    My 03 Ford Ranger has 123000 miles so hopefully it holds for a while longer

  7. That bar leaks stuff it's good sealed an uncles headgasket I was skeptical but works and I used the one with copper in it

  8. I wishhhhhhh he was my Mechanic……Scotty is the Man on these Cars very Smart/common sense, I his Prices are Cheap.

  9. Do you ever re-install the thermostat after doing this if the sealer happens to fix the problem? Also, Do you flush the cooling system after doing this?… thanks.

  10. Hey Scotty my 97 Chevy lumina is having key ignition cylinder issues to the point where all power was cut off in the car and the battery terminals are still connected. I have a Haynes manual and have been reading up on what I have to do. Do you think it’s worth it to do it myself and save money on shop labor?

  11. Just remember the head gasket sealer should only be used as a last resort, replacing the head gasket is always the best option if you can afford it or are able to do it yourself

  12. Hey scotty have a 2008 nissan altima 2.5 tends to over heat when the ac is on for about half and hour driving a round
    What do you think could be wrong

  13. V6 configuration pickup truck is always a bad idea and very annoying to do any service including headgaskets. The 4 cylinder would have been easy to do the work..

  14. I've had a Nissan Xterra and it was a waste of time and $$$ now my wife's friend gave her a Nissan like the one on the video with the same issues, this time I will replace the entire engine and be done with it.
