How can you change the oil on a 1990 Pontiac 6000 LE?

Answer 1

If you are asking this type of a question, then I have to recomend that you don't do it yourself. Take it to Wal-Mart, or where ever, and let them change it. Firstly, You have to get under the car to change the oil. Secondly, changing the oil in any car almost always makes a mess, missing the catch pan, or dropping the drain plug in the catch pan, or whatever.

The reason I said the above is that 6000's came with 2 engines. Althou one is fairly simple to change the oil on, the other is a complete pain.

The simple 3.1/2.8 have a drain plug on the bottom of the oil pan, which you simply unscrew (I believe its a 15mm wrench to get it off), MAKE SURE YOU HAVE A CATCH PAN IN PLACE!!!, and then you take the oil filter off the front of the motor, CATCH PAN AT THE READY AGAIN!!. Put the new oil filter on hand tight (as tight as you can by hand), and put the oil drain plug back in. Put oil in the engine, 4.5 quarts of 10w30 or 5w30 oil, clean up your mess, start it up, and you are pretty much done.

However, the 2.5 engine can be a real pain. There are 2 different types of the 2.5. And in either case, don't even bother doing it yourself. There is a special tool needed to take the oil filter off. And these engine can make more of a mess then any other engine out there.

In either case, once you change the oil, you still are not done. On a 90 6000 LE, and most other 6000's, there are 4 grease fitting on the front chasis that must be lubricated, there are 10 on the AWD model (I own one). Failure to lubricate these can lead to ball joint failure, or tie rod failure. Both fairly expensive to fix at a shop.
