Why would a 1997 Sunfire keep breaking timing chain tensioners?

We had the same problem.It was resolved by using parts from the original manufacturer.When compared to generic aftermarket parts,you can see huge differences in the adjuster,and even in the chain.We used the original sprockets,which were still fine.Contact me for more info if you like.

Timing Chains (2) with respective guides, tensioners and sprockets.

I just found out that it has a timing chain because mine is being replaced.

It must have a TIMING CHAIN because Gates ( they make timing belts etc . ) does not list a timing belt for the 2.2 liter or 2.4 liter engines in a 1996 Pontiac Sunfire

You should always replace the timing chain, tensioners and sprockets whenever you rebuild the engine.

Timing Belt. Mine just went out. You might have to replace the tensioners too. :(

It is not necessary to change timing gears when changing a timing chain unless they have become worn. You won't know if this is the case until you get the cover off and inspect them. It is necessary to change any chain tensioners when you change your timing chain.

You can replace a timing chain on a 2002 Pontiac Sunfire by visiting a local mechanic and having him take care of it for you. This is a tricky part to change yourself.

User Avatar

you have to remove the valve cover , the oil pan and the front timing cover. Then line up all the timing marks and remove the tensioners and guides then remove the cam gears and the chain

User Avatar

normally you shouldn't have to replace a timing chain unless you've been horsebeating your vehicle

User Avatar

All 2002 Sunfires, 2.2 and 2.4, had timing chains

A "timing set" includes all the parts needed (new timing chain, tensioners, sprockets, etc.) A timing set for this car costs $132 and up.

User Avatar

u dont adjust the timing chain tensioner if there is slop or play in chain, u need to replace the chain . good idea to replace timing gears at same time while engine is pulled apart

User Avatar

Normally you will be able to hear the timing chain rattling inside the cover. You may also experience problems keeping the engine in time. A timing chain will last the life of the engine under normal circumstances.

User Avatar

if the timing chain and tensioners are worn out the chain will wear a hole in the timing cover and the oil will get into the water jacket and the antifreeze will get into the oil high time to fix it

User Avatar

very hard! I just finished retapping the cam housing bolt holes in my 2000 sunfire. but had to remove the timing chain to get the cam cover and housing off. to get the timing chain off, you have to remove the motor mount bracket off first, then remove the timing cover before getting to the chain. no room to get the bracket bolts off without some assistance to pry the engine to the opposite side.

AnswerI think this engine uses a timing chain, but I am not 100% positive. Regardless, the noise you are hearing is either a timing chain that is loose or a belt. I would suspect that the timing chain is loose. Have this looked at ASAP.It could also be the timing tensioner also.

Generally speaking, if you have properly maintained and not abused the engine, the timing chain should last until the engine is worn out. If you find that you have any burned valves, by all means replace the timing chain, pulleys and chain tensioners. But a timing chain is not like a timing belt. A belt will wear out after 80K to 100K miles. The chains do age, but since they are constantly in an oil bath, if you've kept the oil clean the chain should last a long time.

User Avatar

Yes, you could. Is it a good idea? Probably not. If the tensioner is worn so must be the chain.
