You should always replace the timing chain, tensioners and sprockets whenever you rebuild the engine.
The belt should be changed every 100,000 miles. Warning, this is an interference engine.
On a 2008 Saturn Vue , you don't mention the engine size , but the 2.4 liter four cylinder uses a timing CHAIN ( also the V6 )
Yes, the V6 Saturn uses a timing belt, and it should be changed every 100,000 miles.
100,000 Miles.
Unless you have other problems, you should only need to change the timing chain whenever you rebuild the engine or remove the head or have other needs to take the front off the engine.
Never. The Saturn S series vehicles used a timing chain instead of a timing belt. And the chain is inside the engine, bathed in oil to keep it lubricated. The timing chain should be replaced whenever you rebuild the engine.
It has a belt that must be changed every 100,000 miles. WARNING: This is an interference engine and if the belt breaks you will have serious engine damage.
It has a chain that should last the life of the engine.
The 6 cylinder Saturns were equipped with the "Ecotec" engine, which used a timing belt. Timing belts fail over time, and Saturn recommends that the belt be replaced every 100,000 miles. The 4 cylinder Saturns all used timing chains. With recommended service and normal use, the timing chain should not fail. It is recommended that you replace the timing chain and sprockets whenever the engine is rebuilt, but otherwise, the timing chain is considered to be quite reliable.
Normally it will last the life of the engine and is changed when the engine is overhauled.
Yes, it uses an internal timing "CHAIN", not a belt. The timing chain should last until the engine needs to be rebuilt.
it has a timing chain, which should be towards the bottom of the engine, and it has a drive belt, which is external and in the front.
