timing chain - ever need service?

Ok so I brought my car in for it's 100,000 maintenance and I wanted to know about the timing belt. Seems my car has a chain, not a belt, and the service manager said he has the same car and that the chain never really needs maintenance. Is this correct? I'd hate to find out the hard way...

Thanks

leave it alone ...totally different from a belt , you`ll hear it even starting to get bad and likely never will .

thanks

Timing belts usually neets to get replaced every 100,000 Km or so, depending on your make.

as do timing chains, they need the tensioners replaced and you should also replace the chain.

i guess you are mister certifited mechanic and all knowing being of RFD? are timing chains made of some super alloy that doesn't wear? are the tensioners made of these same super alloy.

maybe you should take your attitude and timing chain and hang yourself with it.

Check your manual. There are so many different engines out there it's impossible for anyone to guess if your timing chain needs periodic maintenance.

tensioners are one thing, you dont need to change them at an "interval", but you dont need to change the chain at the sametime as the tensioner if they need to.

by your reasoning, since the car is made of metal, if the tensioner is shot, unless the body is made from some super alloy, lets change all the body panels and while were at it the frame of the car too

maybe you should educate yourself on timming chains first.. i would've suggested google but from the other thread you obviously have no idea how to google anything to get meaningful results.

I did consult the manual, but it did not mention the timing chain, nor does GM's general mantenance schedule. This is why I asked the service manager and why I'm aksing here.

Older cars uses chains alot of the newer ones has move to the belt...less damage when they go.

Either one need to be replace after 100K Kms.

quite the opposite actually..

check the new engine configurations.. nissan's engines are mostly chains, gm ones are too.. and I dont know about other ones but those are from my own experience..

Belts break after high mileage. Buddy's Ford Probe/Mazda engine busted on the highway!

Timing chains are suppose to last as long as your engine and dont need service. Service rep at Nissan told me this.
