Where does the power steering fluid go in a 2008 Buick Enclave?

On a 2008 Buick Enclave, You'll need to add power steering fluid to the PS reservoir. This can be a bit difficult to time, because it's located underneath the large plastic engine cover. You'll need to undo the oil filter cover cap, remove the large engine cover, and replace the cap in order to gain meaningful access. Once You're in there, You'll find the reservoir to the left of the engine, on the passenger's side of the vehicle; the cap is quite conspicuous. As far aS-TYPE, the '08 Enclave doesn't seem to be particularly picky. DEXRON-ViAutomatic transmission fluid is often recommended, in lieu of the OEM General Motors specs (the 2008 takes GM89021185). It's strongly recommended You keep at least one of the two on hand, as it's better to be safe than sorry.
