How to Replace a Timing Belt in Your Car
How to Replace a Timing Belt in Your Car


1, 2, 3, 4! Rev up your engines! It’s time for ScottyKilmer.com. Are you worried that the
timing belt on your car is wearing out? Well then today’s your
lucky day because I’m going to show you how to change
a timing belt on an engine. Now the timing belt
connects the bottom of the engine to the
top, to run the valves. And if it breaks, your
car will stop running. Or even worse, if you have
an interference engines the pistons will hit the
valves, bend the valves, and destroy your engine. Now to change a
timing belt, first you got to take the fan belts off. So loosen the nuts and
push the alternator down, and take the belt off. Then you have to take all the
bolts off the timing cover. Then once you get
the top cover off, you’ve got to get the
bottom cover off too. Now the bottom timing
cover is behind the pulley, so you’ve got to
take the bolt off that holds the
harmonic pulley in. Now sometimes you get
lucky and a pulley comes off with your bare
hands, but this one’s on tight. So you’ll need a puller,
like this, to get it off. You install the puller
right over the pulley. Then make these
bolts nice and tight on the bottom that hold it
on, so it’ll pull it off. Then just tighten the
pulley to get it off. And off it comes. Then unscrew the bolts that hold
the cover on, and pull it off. And here’s the timing
belt in all its glory. Now before you take anything
further apart on a timing belt, get some white paint and
a little paint brush, and mark all the cogs so
you know how they line up. Mark the top of the cam and the
backing plate so you know where it lines up. Then mark the crankshaft
and the bottom of the engine, so you
know where it lines. Then loosen the bolt
on a tensioner pulley. Then push down on the pulley
with a giant pair of pliers, and tighten it up, so it
stays in a loose position so you can remove the belt. The
belt just then slips right off. Here it is. Now if you didn’t draw a
picture of where your old timing belt went, it’s a good idea to
have one of these timing belt books. Shows you where they all go. And if your car is more
complicated than this Toyota, and has a lot of pulleys that
need to be lined up correctly, these books will show
you which marks go where. Then slip the belt over the
cogs so that they’re snug. Then loosen the bolt on
the tensioner pulley. And as you can see, it’s
tightened the belt up. And once the belt has tightened
itself, put a wrench on, and make the bolt nice and
snug so the tensioner stays in place. Then put it back in the reverse
order that you took it apart. Start with the
bottom timing cover. Put it back on and
install all of its bolts. And of course, don’t forget
to put the harmonic balancer back on. Slide it on so the
key is on correctly. Then give it a few taps with
a hammer to start it on. Put the bolt in
and tighten it up. Now, once you put
the pulley on, it’s a good idea to get a
cheater bar a socket and turn the engine over
two complete revolutions. And after you’ve done that, you
can recheck the alignment marks to make sure that the
engine is spinning freely and the marks are correct. Then of course, put
the top cover on, and the fan belt. Make sure
the fan belt is nice and snug. Then start her up and
see how she sounds. Now you know how to change
your timing belt. Not that bad of a job, and when you
consider what mechanics charge, you might try the
next one yourself. And remember, if you
have any car questions, just visit ScottyKilmer.com
and I’ll answer them. [MUSIC PLAYING]

    Move Crankshaft + Camshafts to Alignment Marks Before Removing TB.
    After Removing TB – – – Replace Water Pump + Pulleys + Seals.

    Hey scotty, what part of Texas are you from

  11. Larry Leisuresuit says:

    This is TOO CRAZY.
    I Have a Toyota, same configuration as the one you are working on. mines a 2.0 l 1991 camry but the belt and everything are identical. I just do the whole Timing chain, pulleys, tensioner oil pump , water pump deal and when i was doing it, in the middle , generally as i Always do here lately, I come to see your videos and if you do not have one i watch others and wish they were as good of a film maker as you are, LOL So, I did see this video before and many others. Thats not the crazy part.

    I was flipping through channels earlier on the TV. came across a documentary that had already started and i stopped flipping because I thought i saw you, on reg TV.. i was like. WTF? anyway.. i was so convinced i kept watching and then i started really wigging because this dude who i thought was you at possibly a different age or at the very least hair cut in your life turns out to be this lying cyber predator online and eventually a murderer . before the murder thing though i started thinking how amazing it was how much this guy sounds and looks like you. it did occur to me that it was not you at all before the murder part and also before the part where you would be doing 20 years in the pen.

    However. WOW! has anyone ever told you of this ?

  12. KnightGamingDc5_ says:

    Man I'm over here thinking it's harder lol that's why I'm worried about ever recommending something I haven't done

  17. Daniel G says:

    someone know where i buy this book?

  18. TheExxxplicit says:

    Easier said than done. I spilled some coolant on the sprockets where timing belt goes while taking out the water pump. Did not clean it. Is it going to be a problem? It is on Hyundai Accent 2003. As much as I don't want to, I am thinking of redoing it – only the timing belt, though.

  19. Andy Declerck says:

    I got a 04santfea 2.4 I changed the belt and lined every up and pulled the pin on the tensor and spin eng over but the Mark are off by 1 tooth what am I doing wrong?

  25. Tattos & Tactical Arms says:

    I thought you was a creep when I first saw your videos but now I see, your a very talented man. Love all your videos bruh…keep it coming. I'm about to do my timing belt too for my 2007 toyota tundra.

  26. Steve Clark says:

    Why no mention of the possibility of having to use cam locks on some engines? You need to use them on some twin cam engines like an Alfa I owned otherwise they will rotate slightly once you remove the old belt, they are just under so much spring tension.

  27. Speakerbox says:

    Love this guy!

  28. Abitibi_Doug says:

    Wow, you make it look so easy here. Recently I changed the timing belt on my 2002 Honda Accord and it was quite a job, definitely something from the Busted Knuckle Garage. While I got help from another video on how to change that particular timing belt I give you, Scotty, some credit for motivating me to go ahead and actually do it myself.

  33. Dino Dean says:

    hi Scotty, its never that easy….you forgot about replacing the water pump and certain pulleys

  34. Matt Duff says:

    Aside the obvious reason a manufacturer may want to use an interference engine, in order to sell you a new car. Is there any performance or economical reasons why?

  35. Thomas Neate says:

    Scotty, what the hell? are you on drugs? take a chill pill, your to excited mate, pop a Valium or something s#*t

    Dang Scotty! Nice job.

  87. john joe says:

    Scotty I have a question. I need to replace the water pump on a car. Ford was nice enough to design the timing essentials to where the timing belt tensioner is mounted onto the water pump bracket. Videos I'm watching say it needs to be put top dead center and other stuff before putting belt back on. But if I'm not replacing the belt or turning anything then why would I need to top dead center it? Couldn't I just mark it then remove timing belt and tensioner then reverse steps for reinstallation?

    Hey mat I've got a 96 carolla hatchback that needs timing belt done. Do u have any vids of that or links please

  89. Omar Abbaas says:

    Oversimplified, I love your videos but this particular video could get someone into a job they are not really prepared for!

    Man can u do it slowly

  91. Johannes C says:

    Just changed a full timing belt kit Scotty on a Vauxhall Astra. There is an opening between the crankcase and the gearbox on these cars so I could use a crankshaft locking tool. Great because I don't have air tools. Just set the timing marks locked all shafts and renewed the pulleys belt tensioner and waterpump. Also used a cam locking tool. Was an easy job and saved me money.

  92. Johannes C says:

    If you have an old car with very low mileage replace the belt. If your car has reached the manufacturers mileage for replacing the belt your tensioner, idler pulleys and water pump if driven off the timing belt have done the same mileage. Better changing everything than running a new belt on old idlers, water pump and tensioner.

  93. Johannes C says:

    Timing chains give audible warnings when they are worn belts just snap. Belts are one area where if it ain't broken DO change it.

  94. SOG3O M3TRIC says:

    If you just have a crankshaft position error since I have to loosen up the belts is there any re timing of the belts done or do I simply just replace the CPS and put the bolts back in and start the car?. And I keep coming up with P0035 CPS circuit A. I’m about to replace the sensor but would this cause the entire no start or could timing be an additional issue and would it throw off this specific code of the timing was off?. Thank you for your time.

  99. Bob Patterson says:

    Bro a lot of people tune into this video for one reason,you started out with the belt (broke), so since the motor was running when it broke it went out of time so marking the gears and so forth is no good,you have to get back to right alignment, and top dead center ,you lead people (unintentionally of course)..but still please improve you video to help others know ,understand, and accomplish thus part of the job as well so that a person will not destroy their engine but not understanding thus (VERY)important detail..Thanks
