I've got a slightly leaky RMS and just top off the oil every month or so. I put 1/2 quart too much oil this time and instead of doing a complete oil change, wanted to just drain the oil down, but I've never done this.

What's the size of the oil plug? Anyone know off the top of their head? I'd hate to jack up my car, not have the correct size, and have to lower it and put all my stuff away just because I didn't have the right size socket. A set of tools are on the xmas list though !

Anything else I should know? Do I need to buy a new plug instead? Gasket? etc.? Or just take it off, and put it on and torque it to 26 ft-lbs?

Forgot to add - 850 GLT 2.4L

 

Wait, are we talking about the plug on the oil pan or is this a different plug?

If I remember right, it's a 13 or 14. If you have a simple socket set, then you will have it...Make sure you have jackstands when you get under the car.

 

Yeah, the drain plug. 13 or 14, sweet, thanks. It'll be on jackstands, although I'm starting to think about buying a set of those ramps for jobs like this.

I got a set of the ramps. They are great to have.

 

The oil Drain plug is a 17MM.
The transmission drain plug is a 15/16.

 

Whoops, too small lol.

All socket sets should still have a 17mm though... Even the 20 dollar autozone ones...

I have a set of ramps....Unfortunetely my car is sitting so low that it doesn't work...

 

Thanks guys - it was raining here so I ended up taking it to the shop to have them do the oil change.

 

850's are really easy to change the oil on. Shouldn't take more than 15 minutes to do it yourself even the frist time. Mainly because the oil filter is so easy to get to. I always put a low profile pan under the car, jack it up, put jack stands under it, get under take the drain plug out, take filter off, take jack stands out, lower the car onto the pan, let it drain that way for a while, jack it back up, put the jack stands back under it, putdrain plug in, put filter on, take jack stands out, lower car and file er up.Alwaystake drain plug out and then remove the oil filter because the Volvo filters have a realease valve.
