look at how much the engine moves, if moves more than 1" fore-aft, replace. if you can see the rubber in the mount and it is torn, replace. replace the lower mount too
Inspect it and if it looks ok, then use a pry bar to apply upward pressure to the mount. If it is broken you will see it.
While it is possible for an engine to fall out if the motor mounts are bad, it is very unlikely. However, a broken mount will likely destroy the engine if it is not replaced.
Under normal circumstances no, the chain normally needs no replacement. It is designed to last the life of the engine and is replaced during a complete engine rebuild.
If your engine jumps when accelerating, or when certain noises are made when engine torques.
It is important to know the capacity of all the fluid types in a car. IN a Saturn Lw200 a person needs five quarts of engine oil.
Most likely the water pump is faulty and needs replacement.
The chain, if equipped, needs no replacement and will normally last the life of the engine.
This sounds like an engine or transmission mount has gone bad and needs replaced.
Could be a bad ABS sensor. Needs service/replacement.
Yes, it uses an internal timing "CHAIN", not a belt. The timing chain should last until the engine needs to be rebuilt.
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 car needs a tune-up, or the motor mount(s) are bad.
