* A wrench: The most important tool. The drain plug likely uses a 13mm or 14mm socket wrench. Check your owner's manual to be certain. A socket wrench is preferable to an open-end or adjustable wrench, as it provides a better grip and less chance of rounding the drain plug.
* A drain pan: This is crucial to catch the old oil. Make sure it's large enough to hold the capacity of your Catera's oil system (check your owner's manual).
* Gloves: To protect your hands from the hot oil.
* Jack and jack stands (or ramps): You'll need to lift the car safely to access the oil pan. Never work under a car supported only by a jack.
* Wheel chocks: For added safety, place wheel chocks behind the wheels that remain on the ground.
* Wrench for the oil filter (optional but recommended): You'll likely want to change your oil filter at the same time.
* New oil and filter: Have these ready for the refill.
* Funnel: To make refilling easier.
It's always best to consult your owner's manual for specific details and torque specifications for tightening the drain plug after the oil change. The manual will also have the correct size of wrench needed.
