Reference: Saturn Vue Manual
You don't have to use synthetic oil for your Saturn Vue but synthetic oil is said to lead to better performance by the car. Check out this chart on different types of oil that can be used: http://www.synthetic-motor-oil-change-and-filters.com/best-oil/oil-change-saturn-ion-and-vue-ecotec.php
It uses a T45 Torx bit.
The 2.2L Saturn Vue uses a cartridge filter that installs to the right of the intake manifold underneath a black cap. The cap is removed with a 1-1/4" socket. The oil filter I use is Bosch #3324. The 3.5L used a Honda drivetrain and I'm not sure what the filter is for that.
Regular Unleaded 87 Octane.
The 2004 Saturn Vue 2.2L Engine Uses a Timing CHAIN. It is Much better than a belt, and for 2004, Saturn fixed the issue with poor oil pressure on the timing chain and they last much longer than their predecessors.
On top of the engine on the drivers side there is a black plastic cap, with a large plastic nut looking thing. Take that off and you will find the filter.
As you listed this in the Saturn Vue category I will assume you have a Saturn Vue. The 2004 and up Saturn Vue engine was manufactured by Honda and it is an interference engine. The belt and water pump must be replaced every 100,000 miles. All other years used a GM V6 that was also an interference engine. The 4 cylinder Saturn Vue did not use a belt but had a chain.
You should definitely use genuine Honda ATF-Z1 in any 2004-07 Saturn Vue with the Honda 3.5 L V6 installed and nothing else. Any 2.2 L 4 cylinder Vue, or 3.0 L V6 Vue with the GM engine should use only the correct GM fluid.
GM Dexacool or any other brand that indicates it is "dexacool" compatible
The 03 Saturn Vue does not use a stand alone camshaft sensor. The system uses the ignition system as a sensor, tapping into the number one and four cylinder firing systems.
It takes a very short 22mm socket. I actually bought a cheap socket and cut about 5/16" off of it, this is much cheaper than the $25 for the specialty socket.
