What exactly do you need to know about replacing the timing chain? Also you should note that the L200 (4 cyl) has a timing chain. The L300 (V-6) has a timing belt.

Another thing to note is that both of these are interference engines. If your timing chain (or belt) has failed and the engine will not start, the valves are likely bent and you may have damaged the pistons as well.

Saturn never did a recall on them, but a little Googling will find you a wealth of knowledge about the problems that the 2.2L engines had with timing chains...more correctly, timing chain tensioners. It appears that the engine did/does not supply sufficient oil to the tensioner and approximately every 60-80K miles, it will fail and allow the timing chain to jump time. This can be catastrophic if it occurs at speed since the engine had aluminum heads and is an interference type engine. I recommend that if you have one that has failed, repair it and dump it, or just dump it. If you want to keep it, plan on servicing the timing chain every 50000 miles to avoid needing head replacement. My daughter had a 1999 Cavalier with the 2.2L engine. The first time the tensioner failed, it happened as she turned the car off and no head damage occurred. Replacement of the timing chain/gears/tensioner fixed it and then 60000 miles later, on the Interstate, it happened again. This time it took the head with it. Lesson learned.

i recommend that anyone have the timing chain or belt changed at 100,000 miles on any car just as a precaution/ preventative maintenance. you dont want to wait til it breaks or gets loose and jumps timing

to be honest im not sure if you have a timing belt or chain if its a chain i would not worry about it going bad on the other hand if its a belt they do recomend that you have them checked around 100,00 miles. shop around for the best deal and if they tell you it needs changed make them show it to you and tell them you want to compair it to a new one so you can see if its worn out for yourself. never just take there word..it can be a little expensive...

Every dealer wants to do different thing at 100,000, but the average cost is about $400.00. Refer to the owner's manual for what GM recommends

One day at the most...unless the shop is really busy. It only takes an experience mechanic 1-2 hours at the most. MIke. Rate 100% and respond back please.

the transmission normally gets service every 75,000 miles and you don't need the fuel system service

I have the same model. Congrats you made it over a 100,000 miles! Most of them failed after as little as 20,000 or around 78,000 miles becaue there was a design flaw in that the timing chain did not get any oil to it. I had the 78,000 mile engine. Mine failed while driving at 65 miles an hour on the expressway. Pretty much wrecked the engine. The problem with putting in a used engine is that no other type of engine will fit in this car and you can count on engine failure again at 20,000; 78,000 or from what you tell me after 100,000 miles. You would be better off investing in a down payment for a Toyota made here in America that gets over 50 miles to the gallon. I used to be an oldsmobile man and then reluctantly switched to Saturn but am fed up with GM completely now and all american car manufactures.

Get rid of this car. There is a design flaw in that the timing chain does not get oil and will eventually fail. Some failed in as little as 20,000 miles. Mine failed at 78,000 miles which is real common. I just read on here someone was lucky to get over 100,000 miles on theirs but do you really think you will be that lucky?
