What are the timing chains on a Chevy Traverse?

The first pic is of the entire engine/trans assembly out of the Traverse and ready to disassemble. The second pic is a close up of the three timing chains that will be replaced. You can see there are quite a few sprockets, and things to go around!

Do you need to change timing marks on a traverse?

I did change the gears, and yes there are two timing marks, need to align the crank pulley to stage one on the block and than align all marks to the chain on all pulleys on left bank, and than roll engine into stage two and align marks on right bank. Just wasn’t sure if engine had to be TDC before using the marks on the block etc.

Are there any timing chain problems on the GMC Acadia?

Chevrolet Traverse And GMC Timing Chains Replacement. A big thing we’ve seen a lot of over the past year or so, has been timing chain problems on the Chevy Traverse, Saturn Outlook, GMC Acadia, and Buick Enclave.

What are the causes of timing chain failures?

The most common cause of timing chain tensioner/chain failure is low engine oil. If you follow the MINI/BMW maintenance intervals an oil change is only recommended once a year or every 15,000 miles.

What causes a timing chain to go out?

Furthermore, the chain tensioner or the guides that are connected to the timing chain may wear out as well, causing the timing chain to fail completely. If the chain fails, the vehicle will not run at all. One cause of the timing chain wearing out faster, is using the wrong oil.

Is timing chain failure catastrophic?

In severe failures on some engine models, a broken timing chain will cause the valves to come into contact with the pistons, resulting in very loud knocking and banging noises, catastrophic engine failure, and destruction of the valves and pistons.

Do timing chains break?

Timing chains are rarely known to break during an engine’s typical lifetime. If a timing chain is not properly tensioned, it may develop slack, which can result in chain-slap and premature fatigue. Cracks in the chain may develop, resulting in failure.
