did you know that nearly 70% of the
0:02
weird noises your car makes can be fixed
0:04
without ever stepping foot in a mechanic
0:06
shop that's right most of those squeaks
0:09
rattles and clicks are easy DIY fixes
0:12
you just need to know what to listen for
0:14
and how to stop them in this video I'm
0:17
going to show you how to fix the most
0:18
common car noises yourself no fancy
0:21
tools no overpriced shop visits just
0:23
quick and easy solutions you can do
0:25
right now let's get started one
0:29
squealing when braking one of the most
0:32
common noises drivers here is a
0:34
high-pitch squealing when applying the
0:37
brakes this usually happens because the
0:39
brake pads are worn down and the wear
0:41
indicators are scraping against the
0:43
rotor in some cases it's just rust or
0:46
dirt on your rotors especially if your
0:48
car has been sitting for a while before
0:50
you panic take the car for a short drive
0:52
and gently apply the brakes a few times
0:54
in an open space this can scrape off the
0:56
surface rust and eliminate the noise if
0:59
you ignore this noise for too long your
1:01
brake pads will wear out completely
1:03
leading to metal on-metal contact this
1:06
will not only increase stopping distance
1:08
but also cause damage to the rotors to
1:10
fix this inspect the brake pads and
1:12
measure their thickness if they are less
1:14
than 3 to 4 millimeters thick replace
1:17
them immediately if the pads are fine
1:19
try cleaning the rotors with brake
1:21
cleaner or resurfacing them if they have
1:23
grooves regular brake maintenance can
1:26
prevent this issue from happening in the
1:27
future two grinding noise while braking
1:31
if your brakes make a deep grinding
1:33
noise it's a sign of serious trouble
1:37
this usually happens when the brake pads
1:39
are completely worn down allowing the
1:41
metal backing plate to grind directly
1:43
against the rotor the longer you drive
1:45
like this the more damage you'll cause
1:47
potentially leading to the need for
1:49
expensive rotor or caliper Replacements
1:52
to fix this noise immediately inspect
1:54
your brake pads and replace them if they
1:56
are worn out if the rotors have deep
1:58
grooves or warping they may need
2:00
resurfacing or replacement to avoid this
2:03
issue always listen for squealing noises
2:05
before they turn into grinding and
2:06
regularly check your Brak pad thickness
2:09
three clicking sound when turning you're
2:12
making a turn and suddenly click click
2:15
click no it's not Morse code that's your
2:18
car screaming for help but before you
2:20
freak out let's diagnose it most of the
2:23
time this clicking noise comes from your
2:25
CV joints CV joints allow the front
2:28
wheels to turn smoothly while delivering
2:30
power from the transmission when they
2:32
wear out usually due to torn rubber
2:33
boots allowing grease to escape they
2:35
begin to make a rhythmic clicking noise
2:38
if left unfixed they can fail completely
2:40
making the car undrivable to diagnose
2:43
the issue Drive in a tight Circle and
2:45
listen for clicking noises if they get
2:47
louder the CV joints are likely the
2:49
problem to fix this inspect the CV boots
2:52
for tear and replace the entire CV axle
2:56
if grease has leaked out regularly
2:58
checking and replacing CV joint boots
3:00
can prevent costly repairs down the line
3:03
four rattling under the car if you hear
3:07
a rattling noise under your car it's
3:09
likely due to a loose heat shield a
3:11
damaged exhaust component or a failing
3:14
catalytic converter heat shields protect
3:16
your car from excess heat but the bolts
3:19
holding them can rust over time here is
3:21
a simple fix crawl under your car give
3:23
it a shake and tighten any loose bolts
3:27
if the shield is completely rusted off
3:29
you can remove it temporarily but
3:31
replacing it is best a loose exhaust
3:35
pipe or Muffler can also cause rattling
3:37
especially over bumps if your exhaust is
3:40
bouncing around use a cheap rubber
3:42
exhaust hanger to secure it five hissing
3:46
from under the hood a hissing noise
3:48
coming from under the hood usually
3:50
indicates a vacuum or coolant leak
3:52
vacuum leaks occur when air escapes from
3:54
hoses gaskets or intake manifolds
3:57
causing rough idling reduced fuel fuel
4:00
efficiency in potential check engine
4:02
lights coolant leaks on the other hand
4:04
happen when a radiator hose or heater
4:06
core develops a crack allowing coolant
4:09
to escape a steam if the hissing is
4:11
accompanied by a burning smell or
4:13
overheating stop the car immediately to
4:16
prevent engine damage to fix this
4:18
inspect all vacuum hoses for cracks or
4:21
loose connections and replace any
4:22
damaged ones if coolant is leaking check
4:25
for white residue around hoses radiators
4:28
or heater cores and fix the leak before
4:31
refilling the system regular hose
4:33
inspections can help prevent this issue
4:36
six knocking or pinging from the engine
4:39
if you hear a knocking or pinging noise
4:41
coming from the engine especially when
4:43
accelerating it could mean your engine
4:45
is experiencing detonation knock this
4:47
happens when the air fuel mixture in the
4:49
cylinders ignites unevenly causing small
4:52
explosions instead of a smooth burn the
4:55
most common cause is using lowquality or
4:57
incorrect octane fuel but carbon buildup
5:00
on the Pistons faulty spark plugs or
5:04
improper ignition timing can also
5:06
contribute ignoring this noise can lead
5:09
to severe engine damage over time to fix
5:12
it first try using higher octane fuel as
5:15
recommended in your owner's manual if
5:17
the noise persists inspect and clean the
5:19
fuel injectors check the spark plugs for
5:21
wear and ensure the ignition timing is
5:24
set correctly keeping your engine
5:25
properly tuned will help prevent
5:27
knocking seven banging or backfiring
5:31
from exhaust a loud bang or popping
5:33
sound from the exhaust is usually caused
5:35
by unburned Fuel igniting in the exhaust
5:37
system this happens when the air fuel
5:40
mixture is too rich faulty spark plugs
5:42
are misfiring or the ignition timing is
5:45
off backfiring is a serious issue
5:48
because it can damage the exhaust system
5:50
and catalytic converter to fix this
5:53
check the spark plugs and replace any
5:55
that are worn out inspect the fuel
5:57
injectors for leaks and clean them if
5:59
necessary Neary ensuring the proper air
6:01
fuel mixture and ignition timing will
6:03
help prevent backfires that's all for
