What does ''timing belt change'' include?

my car is over 100 k miles, they suggest me to change timing belt.

what i wanna know is , what does this work include?

if only change a belt maybe i can do it my self ,and that belt will be within $50,

or is that also included changing the gears and something else?

the auto repair store ask me like $400 for the whole thing.

what will they do? no only change belt,but also change something else?



so if i can do it myself, is there something i need to know?

thanks

first make sure your car has a belt and not a chain. $400 sounds normal but high TO ME. I can find a shop to do it for maybe $250. Keep shopping around. Given how/ what you have said I doubt u have the knowledge to do the job yourself. Bit complex for the average joe and requires full tool set and torque wrench.

They'll probably also change the water pump which is usually done.

ps- if u have a timing chain u can hold out for 35k more miles.

pss- requires timing belt, water pump and corresponding gaskets.

your not gonna do it unless you have done it before which you havent. pay the shop to it. its a 3-4 hour job depending on how many guys are there to help.
That depends on the car. On a '91 Toyota Camry, they changed just the timing belt last year and now this year we have to change the water pump which was uncovered when changing the timing belt. They SHOULD have changed the water pump because the car had 225,000 miles.

They didn't so now we have to.

Look up how to do your car and if it's the transverse engine, it probably should have everything that gets unbolted and is hard to get to, changed.
please don't do it yourself. if you get it a tooth out it will run terrible and you'll have to tear it back down. but do have it changed. depending on the vehicle if the belt breaks, which at 100000 you're flirting with disaster, it can bend valves and/or bust pistons. it also depends on the vehicle how much labor is involved. that sounds reasonable and i have done alot of them that cost that much. you may also need idler or tensioner pulleys if they get in there and find some bad, which is normal. also if the water pump runs off the timing belt it is sometimes a good idea to go ahead and replace that also and save some labor. that is if it's questionable.
Don't know what kind of auto you have !
The belts themselves are cheap: $50 or less. Getting to them, however, takes a couple of hours of work, and that's if you've done this procedure several times and can practically do it in your sleep. Most of us aren't so skilled. I know I'm not.



At the very least, they'll check the timing before they reinstall everything, and check the tension on the belt.



You shouldn't have to do this more than every five years or so; just bite the bullet and try to smile. Or think of what will happen if the belt breaks. If you're lucky, you'll be stranded somewhere. If you're not so lucky, because your engine was designed with an interference fit, you'll be writing a check for the top half of the engine.
