    How To Change The Timing Chain In The New Corvette

    The front of the engine is so close to the firewall that mechanics some years from now having to change the accessory belts or timing chain will be cursing the design engineers because they left no room to pull out the old belts or install the new ones.

    The car will have to be hoisted so the mechanic can crawl underneath. Then the engine (in front of the rear axle) and the differential and 8-speed dual-clutch transmission (extending behind the rear axle) will have to be unbolted as a unit and lowered from the chassis far enough for mechanics to access the belts, GM engineers confirm.

    Here's hoping GM is using very heavy duty accessory belts and timing chain on the (stunning) new Corvette.

    Click the link and read the whole article - it's a great read!

    Oh well...that's not a negative as most buyers won't be turning their own wrenches anyway, that isn't their expected clientele...it's an $85k supercar beating mid engined Corvette, if you need to get something done maintenance wise, take it to the dealer like everyone else who owns an Exotic does.

    You can offset it against the $100k+ savings vs. buying the Euro equivalent!

    Kidding aside, anyone with more knowledge on repair costs want to make a guess at how much this will cost to replace? I assume it will be several thousand $$.

    That looks like a chain to me.

    It's a chain. The article talks about accessory belts and timing chains. They are not the same, and this is poorly titled as a result.

    Re: How To Change The Timing Belt In The New Corvette

    Obviously GM small blocks donít have timing belts, so in the unlikely event that the chain breaks or must be replaced, itís pretty likely that the engine would have to come out anyway, as it would very likely be catastrophic. Most of the time, I think timing chains are replaced on ohv V8s as preventative maintenance when youíre doing something else in there.

    Iím skeptical that they would build a car where the accessory drive belt canít be changed with the engine in the car. It doesnít take tons of room to do it, and for many years mechanics have been changing them in tight spots on FWD vehicles. Even if GM doesnít recommend it, I wouldnít be surprised if someone figured out a way to do.

    The downer might be that the engine may have to be dropped to do the water pump. Not exactly an uncommon failure on high mileage vehicles, LS engines included, it would be an expensive pill to swallow around at 100k miles or so.

    Corvette uses a chain. Many manufacturers still use belts.

    That was only for the supercharged 3.8, no?

    I would guess not on that. But I'll look it up.

    Never mind, no handy list at doctor google.

    I suspect you are right. After all, they set it up so a DIY can do the oil change, something quite unusual for a mid engine.
