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.
Not Applicable The Saturn 4 cylinder, both the SOHC and DOHC used a chain, and it doesn't need to be replaced unless the engine has OTHER problems.
every 90,000 miles average to replace timing belt
I believe you need to replace a timing belt. Cause it uses timing chain which doesn't required to change as timing belt.
Timing BELTS are outside the engine, run dry, and have no external lubrication. Timing BELTS should be replaced according to the manufacturers schedule. But the SL2 is not equipped with a timing belt, it uses a timing chain. Timing chains are internal, well lubricated, and designed to last as long as the rest of the engine. You shouldn't need to replace the timing chain until you rebuild the engine.
how do i change timing chain on 95 saturnsc1 1.9 sohc
there is no timing belt -- only a timing chain that does not need to be replaced
Early Saturn VUE's use a Opel designed V6 engine. This engine is also used in the Cadillac Catera, Saturn L series, and Saab vehicles. This engine does use a rubber timing belt that does have to be replaced every 90-100k miles. It should be noted this engine requires some very special tools to replace the timing belt. Pretty $$ tools. The tools can be rented here for 30 days: http://www.ledfix.com/timingbelttoolrental.html
The Saturn VUE uses a Opel designed and manufactured GM V6 engine. This V6 engine is also used in the Cadillac Catera, Saab, and Saturn L vehicles. This engine does use a rubber timing belt and needs to be replaced every 100k. If the belt fails, you will suffer severe engine damage. The j42069 GM V6 timing belt tools are required to replace the belt on this engine and can be rented here: http://www.ledfix.com/timingbelttoolrental.html
the ignition timing does not get replaced on 87 dodge.
You do not have to replace the timing belt but you will have to remove it in order the replace the pump. Unless the belt is pretty new I suggest you replace it at the same time you replace the pump. The pump should have been replaced when you replaced the belt at 105,000 miles.
Typically a timing chain does not fail since it runs in an oil bath. Of course, any physical component of a vehicle CAN fail, but timing chains typically do not need to be replaced until you rebuild the engine. A good general rule is, replace the timing chain whenever you work on the valve assembly.
Timing chains are designed to last the life of the vehicle. They are normally replaced during a complete engine overhaul.
