Depends on what kind of vehicle it is. On most you have to drop the oil pan, pull the water pump, pull the valve covers and sometimes the heads, but not always, and pull the timing chain cover to get to it. You will probally have to pull the distributor out as well. There should be timing marks on the timing pullies that need to be lined up when you change the chain. Your best bet for this job is to get a good manual and read up on it, then follow it step by step.

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.

You cannot adjust the tensioner. It is automatic, and takes out the slack of a stretching/aging cam chain. Once the tensioner has fully extended, the only fix is to replace the chain and the part of the tensioner the chain rides on if it is worn.

That ACTUALLY means that you probably didn't need to replace the timing chain in the first place. If you did it yourself, did you replace the tensioning rails? Check to see if they're worn. Note that one of the tensioning rails connects to a piston actuated tensioner assembly; if it isn't functioning properly the timing chain tension will not be maintained. Also, if the engine has low oil pressure, the tensioner will not function properly and you may end up with a loose timing chain.

If the timing chain on your Lincoln LS is worn out then it should be replaced. A worn out timing chain can jump a link, or more, and the engine will ultimately not be able to run. Normally the timing chain will last the life of the engine.

Worn belt or belt that has stretched to the point the tensioner cannot keep the proper tension. The tensioner can also be defective. Replace the belt and the tensioner.
