Saturn timing chain

Since the inception of the internal combustion engine, one constant has remained — all of them have a timing chain or timing belt. Most higher-displacement engines have a timing chain as opposed to a timing belt. The chain is located in the front of the motor and is attached to a set of gears and pulleys that power multiple mechanical components, including the crankshaft and camshaft.

In order for your engine to fire, the timing chain must smoothly rotate around the gears without hesitation.

Although the timing chain is made out of metal, it is subject to wear and tear and may break if not replaced as recommended by the manufacturer. The timing chain is comprised of a series of links in the chain — similar to those found on a bicycle chain. The links move on the toothed sprockets which are located on the ends of the crankshaft and camshaft and are responsible for opening and closing valves in the cylinder head and moving pistons and connecting rods in the combustion chamber.

The timing chain can start to stretch and wear over time, which will cause the engine's timing to be inaccurate and produce a few warning signs. Listed below are 5 of the symptoms of a worn out timing chain. If you notice any of these warning signs, it's advised you contact a local mechanic as soon as possible to diagnose the exact cause and make appropriate repairs as needed. There are two ways to achieve valve timing in a combustion engine. The first is the two-gear method, which includes the crankshaft to camshaft gear direct connection.

This is the method used in most types of heavy equipment and big trucks.

The timing chain method is more common with consumer vehicles and high-performance engines. Over a period of time, the timing chain can stretch, which can cause the chain to skip a gear on the cam or crankshaft. The engine may also run poorly and lack accelerating power. If this situation occurs, it's likely the timing chain is damaged and needs to be replaced as soon as possible.

If the timing chain breaks, the loose metal rolling around inside the motor can lead to serious engine damage. It's recommended by all automotive manufacturers to change the engine oil and filter every 3, to 5, miles. Over time, oil begins to separate as it heats up and is exposed to natural solvents found in gasoline. If the timing chain begins to wear out, small metal pieces can break off the chain and find their way into the oil pan.

When you have your oil changed, and the mechanic tells you there were small pieces of metal inside the oil as it drained or in the filter, it's a good indication that your timing chain is beginning to fail. Metal shavings are also commonly seen when there is extensive wear of cylinder head valves, keepers, retainers and other cylinder head hardware.

A broken timing chain will cause an engine to not start or fail while driving. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.

The check engine light can illuminate for a variety of reasons, one of which could be a failing timing chain. The check engine light may turn on when the onboard computer detects something wrong with the emissions system and engine operation. A stretched timing chain contributes to poor engine performance and increased emissions, triggering the check engine light and the storing of a diagnostic trouble code.

A mechanic will need to inspect the code and prescribe the necessary repairs.

Unusual sounds are also a common warning sign of a problem inside your motor. Under normal conditions, the engine should have a consistent, smooth sound indicating everything is running as it should.

However, when the timing chain is loose, it may cause a vibration inside the motor and that will produce a rattling noise as the engine idles. Anytime you hear a rattle it means something is loose and needs to be fixed before it breaks. The timing chain is an integral part of any engine, and without it, your vehicle is rendered useless.Search thousands of topics on CostHelper.

The only mentioned way I have seen to prevent this problem is frequent oil changes, changing the oil when the car tells you to is NOT enough.

As others have griped about, it is a very common problem with this car, buyers beware! This is the second Timing Chain that failed at 80, miles February The Original Timing Chain failed at 56, miles in March of Both were repaired by an authorized Chevrolet Dealer. Yes, 2 years 11 months and 24, miles and the Timing Chain needed replacement.

Something is inherently wrong with the engine design. It is unacceptable for a vehicle to require a Third 3 timing chain. I believe the Cadillac has the same engine that my Saturn XR has and they have fixed their problem. I had my vehicle in to a GM Dealership they told me the problem but did not tell me that the Cadillac CTS with the same engine gets fixed at no cost.

WTF is up with that. All I am asking is to get the same deal that the Cadillac owners received. I do have the10 year warranty also and I have only 46, miles on this vehicle and my wife loves it and we used it to transport our Daycare children in.

Going through inspection my service light was on. I was informed that my camshaft correlation was the problem. I made an appointment with the dealer and after his testing was informed that the timing chain has stretched and need to be replaced to correct this problem. I found that a service repair was issued by GM C but did not cover the Aura but it has covered about 4 other type of vehicles with the same engine.

I want to know why the Aura is not covered. I put a complaint into the hwy group also. The check engine and Service traction control lights came on on my way home. I took it to my local mechanic and was told that the Timing chain was stretched.

The timing chain should last the life of the engine or at least longer the 86K miles. After researching this issue it became apparent that GM has not only known about the issue for a multiple years but is doing little about it. Their solution is to change the parameters on the sensors to allow for more of a deviation in other words allowing the problem to continue and not throwing a trouble code until after the vehicle is out of warranty.

I contacted Saturn and they said they are aware of the technical bulletin but since my vehicle is out of warranty they will do nothing to assist.If we can't tunnel through the Earth, how do we know what's at its center?

Upload Photo Photo optional. Related Questions. Start a new Saturn VUE question. Saturn VUE Experts. Find great deals from top-rated dealers TM Search.Back inwe notified you of a defect petition we submitted to the National Highway Traffic Safety Administration NHTSA in reference to engine stalling and engine timing chain failures in Saturn L-Series vehicles with the 2.

The engines, our petition alleged, have defective timing chains with an oiler nozzle that does not provide adequate oil flow, which potentially cause catastrophic engine damage. Under extended low rpm idling, the timing chain may not have the proper amount of oil delivered to it, increasing the stresses on the chain and increasing the risk of failure. Over time, the chain could break or skip teeth on the gear, causing damage, potentially at highway speeds. The manufacturer was aware of the problem for some time, having released the new design chain for its model year.

In fact, after there have been no complaints of engine damage due to timing chain failure. While under investigation, the number of complaints continued to rise. Almost two years after filing our petition and what can only be numerous engine replacements at consumers' expense, General Motors decided to conduct a recall into only some of these vehicles. The defect could result in engine stall while driving with no restart.

GM will recall 07v the vehicles to replace the timing chains with redesigned parts. During this engineering analysis GM and ODI contacted Saturn owners that had warranty work performed related to timing chain replacements or repairs in order to determine certain safety consequences associated with timing chain failure.

The surveys were also used to assess the safety consequences of the SWD incidents.

The calls found that none of the vehicles that experiencing stalls due to timing chain failure could be restarted. GM's statistical analyses of failure data estimated stall while driving rates of 1. ODI's analyses estimated slightly higher rates of 2. This engineering analysis is closed based on GM's recall.

We were not satisfied with recalling only some vehicles "If the manufacturer conducts a recall of any size, NHTSA will consider the matter resolved," continued Lamb. That's not right! A manufacturer generally must also compensate consumers for repairs performed out-of-pocket for an issue for the preceding year before a recall is issued or during an engineering analysis.

We do not believe so. The complaint data listed on the NHTSA website indicates that the timing chain problem is not isolated to vehicles produced during this four-month period.

In fact, a Saturn L-Series vehicle with a 2. NCCC again petitioned NHTSA to have all Saturn L-Series vehicles with the affected component recalled and repaired free-of-charge; however, as of April NHTSA has determined that continued investigation is not an appropriate allocation of resources despite the subject vehicles continue to experience failures.

NHTSA cites that in the seven to nine year life of the subject vehicles no crashes or injuries have resulted from the failures. No crashed or injuries does not mean that the potential for crashes or injuries is not present, especially when dealing with a defect that can leave a consumer in traffic. On October 16,ODI granted dp and opened pe to investigate timing chain failures resulting in engine stall while driving SWD in the Saturn L-Series vehicles equipped with L61 engines and that used the same design timing chain and timing chain lubrication system as the recalled vehicles.

A redesigned timing chain and lubrication system were implemented late in my production may 1, Hence, the subject vehicles for this investigation are all MY through Saturn L-Series vehicles equipped with 2. In this investigation, ODI analyzed updated complaint and warranty claims data for timing chain failures resulting in incidents of engine stall while driving, which comprise slightly over half of all timing chain failures occurring in the subject vehicle population.

ODI's analysis of complaint and warranty data shows that vehicles produced with the subject timing chain and lubrication system experienced elevated failure rates when compared with the my through vehicles using the revised components.

However, the analysis also showed that the my Saturn L-Series vehicles recalled in 07v experienced a significantly higher rate of timing chain failures than the subject vehicles. The complaint rate for timing chain failures resulting in SWD was approximately 5 times higher for the recalled vehicles, The warranty claims rate for chain failures resulting in SWD was over 3 times higher for the recalled vehicles, 2.

The complaint and warranty rates for the subject vehicles were similar to rates recorded in other recently closed investigations for conditions that could result in SWD with no engine re-start, ea and ea Analysis of all complaints, field reports and warranty claims found no allegations of crashes or injuries associated with the alleged defect in the subject vehicles after approximately 7 to 9 years in service.

ODI's analysis of the stalling incidents that have resulted from timing chain failures in the subject vehicles found that they can occur at any speed and almost always result in a no restart condition.

These are generally considered to be factors that increase the severity of stalling incidents. However, analysis of SWD failure rates in the subject vehicles show that they have occurred at much lower rates than were observed in the recalled population. In addition, the SWD complaint and warranty rates for the subject vehicles are similar to rates observed in prior investigations involving similar categories of engine stall consequences that were closed with no action. Further investigation of this matter would not be an efficient allocation of agency resources.When aggressive drivers want strength and quality they think of vehicles manufactured by Saturn.

Your car or truck definitely requires the best components that you can find. Successful automobile manufacturers understand the basic importance of great performance.

Many vehicles, and especially those built in the last decade, often use a Saturn Vue Timing Chain for synching the crankshaft and cam shaft rather than a belt made of rubber.

Your vehicle's Timing Chain matches the engine's pistons with the cam shaft. Replacing your Timing Chains will keep the vehicle from being damaged and keep the vehicle running. Even though Timing Chains are hardier than timing belts, they can still break and result in serious damage.
