there is a priming procedure to prime the chain tensioner with oil before you start your engine. you need to set the tensioner all the way in, lock it in place with a 1/8 drill bit. bolt it to the engine block. when all the components are installed and ready to be tentioned, remove the drill bit and the tensioner will expand to place tention on the chain. as it is extending, it is pulling oil through a small passage behind it, lubricating the tentioner. This would be the only reason I can see the unit failing twice.
You don't. The YFM225 uses an automatic chain tensioner that helps to take up the slack on the cam chain. If you are getting chain slap, then either the chain is stretched or the tensioner is not functioning correctly. In both cases, the parts should be replaced. You cannot repair a non-functioning auto tensioner, nor can you remove links from a stretched cam chain.
Chain -No maintenance required unless noise detected - Guide/tensioner has plastic parts that can break/wear out with age, lack of lubrication or overheating. Generally, very durable engine if maintained properly.

A loose timing chain can only be repaired by replacing the timing chain . A loose timing belt means the belt is worn out or the tensioner is worn out. Replace worn parts.
If they share a common engine then it may. The 8th digit in VIN is the engine code. You can also tell by visually ensuring parts are identical.

To replace the timing chain on a 2.4L olds Alero you need to remove many parts. The parts that need to be removed are the drain coolant, the alternator, the air conditioning compressor, the water pump, and the harmonic balance. Once these parts are removed, you will need an engine hoist to lift the engine.

The Saturn Car company is now defunct. There is no main office for Saturn Car parts. If one is looking to purchase a part for a Saturn car, they should begin by looking at the local auto parts store.
General Motors is still supplying parts for Saturn automobiles, so a GM dealership would be the best place to look for Saturn Parts. Auto Parts Warehouse or eBay are also possibilities.
The system should have an automatic belt tensioner. If the belt is loose the tensioner must be shot. The tensioner is available from your local auto parts store.
The timing chain tensioner for the 1.6L engine? If so it has two. One is located behind the inspection panel located above the fan belt main pulley just under the valve cover. Two nuts and a six 10mm bolts hold it in place. It is sealed with silicone engine sealant. Support the engine from underneath and remove the top motor mount for easier access. Two bolts hold it in place. Auto parts stores sell it for around $50. The second tensioner in found in the lower block area behind the timing chain cover/ water pump. That tensioner is made up of two components. The spring tensioner which can be removed from the engine easily. Remove the two bolts on the side if the engine directly behind the water pump output and it pulls right out. The other component is the nylon tensioner track or guide that actually pushes against the timing chain. That is the part that wears out and requires the cover to be removed. To remove the cover you have to remove all the 10 mm bolts including the two in the top from the head and two in the bottom from the oil pan. There is also two 12mm bolts near center the cover near the water pump. Removal of this cover my damage the head gasket part that seals the head above to the cover. I have always pulled the head off the engine and replaced the head gasket when opening the timing chain cover. I don't know if it is possible not to without causing oil leaks by not replacing the head gasket. Here is a link to a photo showing the upper cover removed. http://www.flickr.com/photos/92225127@N00/534508640/in/photostream/
