Know When to Replace Your Air Filter

hey how's it going guys Andrew here back

again I'm gonna do another auto andrew

tip of the day and since we talked about

windshield wipers yesterday and passing

inspection I figured I'd talk about air

filters today or your air cleaner this

is another common thing that you know

like oil change and lube places like to

look at and I like to charge you a lot

of money to replace it so I've gone in

done a little research and I want to

tell you guys what I've learned about

when you should replace your air filter

kind of what to look for symptoms wise

when you need to replace it and all that

kind of stuff so check it out okay so to

kick this off for those that don't know

your air cleaner is in your engine bay

so you're gonna want to go under your

steering wheel and pop your hood and

we'll come around here go around for the

little latch razor up I mean you usually

see some kind of big hose or something

coming from your engine and your air

cleaner will usually be located along

the front edge on either side inside a

box like this so what you'll want to do

is you want to take off any screws or

any kind of attachment points some of

them just you can unclip open with some

plastic clips they're easier to get into

than this but you'll just want to open

this up and take a look so I'm gonna

take a moment and unscrew mine and we'll

look at what's going on so after

unscrewing the screws as you can see you

can open up the air box there's the

other side of the hose where the air

goes to the engine you know so you just

want to take a look around in there you

can see I've got a little bit of debris

bug bodies and stuff but here's the

filter that those Lube places like to

change which is not a bad thing but it's

just they usually end up charging a

little bit more than it would be to just

get the part and do it yourself and it's

very easy so I recommend that you do it

yourself well just gonna look at this

one you can see I've kind of got a

little bit of debris in there and it is

fairly dirty and it's been probably a

year so since I've changed this so I

could probably change it and it wouldn't

you know wouldn't be a bad thing but

this is still pretty much kind of an OK

filter I think you could get by on this

one for

a little bit longer because as you can

see the dirt doesn't go all the way down

the fins it's kind of just right on the

edge so I'll probably just shake this

one out maybe vacuum it put it back in

call it good

charge it at a later date another thing

I wanted to point out on GM vehicles at

least and I'm sure some other vehicles

have this you've got this kind of

resistance indicator on the airbox and

it lets you know the resistance coming

from the filter on the airflow so see

right here I've got probably I'm not

sure what the interval is here but I'm

only on the first interval so when once

it gets down here in the red this thing

will tell you when it's time to replace

it as long as it's functioning correctly

and then you can just replace the air

filter hit this button right up here on

the top to reset it and you'll be good

to go so that's kind of just a quick

overview on air filters and kind of how

to find them get them out take a look at

them so before you go to taking all this

apart you're probably wondering you know

what kind of symptoms a dirty air filter

will give you so that you'll kind of

know what you're looking at before you

go in here and tear all this apart and

one of the first things you'll notice is

a decreased fuel efficiency so you'll

get a lot smaller miles per gallon

number and that's just because the ratio

of the air & fuel mixture in your

vehicle is having to struggle a little

bit for that reduced air that's coming

in this little box right here has to

suck about 10,000 gallons of air in in

order to burn one gallon of fuel so

that's a lot of air that's flowing

through this all the time so that's why

it's very very important to keep this

thing clean and that's also why the

mixture can get messed up because this

thing's pulling a lot of air so if it's

clogged you'll notice decrease fuel

efficiency another thing that can happen

is the change in fuel ratio and actually

cause your spark plugs down here to foul

out because of an increase of fuel going

in and you'll get a lot of carbon

buildup and stuff like that so your fuel

light can actually or your check engine

light I mean can actually come on on

your dash and that'll be you know that

can happen because of carbon buildup or

fouled plugs so that's another thing to

look out for with the dirty filter so a

few other things you can notice if

you've got a clogged air filter is

usually kind of a rough start

and also rough idle can happen because

the engine is struggling to pull air in

from the intake you can also notice

rough acceleration for the same reason

because as you mash on the pedal it's

having a hard time getting air and to be

engine to compensate for you know your

increased desire for power so those are

things to look out for as well just keep

an eye on your miles per gallon

indicators if you have them or if you

have a log and also check out to see if

you've got some of those air restriction

indicators on there because those can be

great tools so moral of the story should

you get this thing changed at your next

oil change or when the guy recommends it

at the mechanic shop yes and no it

depends on if you want to deal with it

yourself and maybe save a couple you

know 25 bucks or something like that

or if you just want to let them handle

it and like get your hands dirty like

this but the recommended interval

changes per vehicle and per driving

conditions so it's kind of hard to

recommend a catch-all interval I'm going

to change these things but I recommend

you look at your owner's manual

it'll have maintenance schedules in the

back on when you should change these and

under what conditions typically a good

average is something like 15 every

fifteen thousand miles every other oil

change or you know if you're in dusty

conditions you may have to change it a

little quicker once a year is also a

pretty good average to go off of just

make sure you change this thing you know

fairly frequently but try to do it in

the most cost-effective way you can

because a lot of times you know I know

at one local shop here they charged like

75 or 80 dollars to change one of these

and that just seems a little high to me

because I know these filters at least

from my truck are somewhere in like the

forty five to fifty dollar range maybe

sixty dollars for a really good one so I

know I can save about $20 changing this

myself the way I just showed you as

opposed to having them do it and you

know that's money well saved to me I can

put that money into something else on

the car or the truck or you know go have

a nice meal or something anyway so

that's today's Auto Andrew tip of the

day hope you guys enjoy this video I'm

going to try and do a couple other

things that revolve around getting your

state inspection

you know when you take vehicles into

like lube places what to look for

because those guys like to upsell you on

things that you can do yourself and save

a little bit of money anyways that's

today's tip of the day air filters go

check them out make sure they're clean

get them changed if they're not and try

to do so on like a regular interval so

you can hey save money on gas and you

know be save money doing it yourself
