Oil Change hose coupling size X-30
Wow the shop rates are climbing in Cincinnati as I just paid $130 for an oil change and that will be the last one for me. I do have the suction type oil changer but that takes hours to get the old oil out so I want to install the hose that connects to the oil pan drain plug and has a valve in it and then the hose goes out the drain hold so I can put it in a closeable container to recycle. Does anyone know what size I need to connect to my X-30 drain plug??
It is my experience that draining through the hose will be even slower than using an extractor pump. If I use an extractor pump, it takes just a few minutes. I have the hose in my boat so I made up an adapter to connect the extractor to the hose. If you do some searches on this forum you will find others who use the extractor to speed up the process and others who just wait overnight...
Anyways, SKIDIM has oil drain kits at http://www.skidim.com/products.asp?dept=1054. There is one for "1996 and Up GM Oil Pans with metric thread oil drain fitting" and it says it is 12mm thread. But I would suggest contacting SKIDIM and verifying that is correct.
If the engine is not run on the trailer to 160 for ten minutes, it's slower than cold honey out the hose.
It's the first statement in the manual for changing oil.
With vacuum on the drain hose out the bottom, it took less than a minute.
With engine still warm, quart was added till it came out the hose clean.
Now I know it's a clean sweep in the crankcase.
The drain hose should anchored to a clip near the top front of engine near the oil cooler.
This is where it is on the 209.
The biggest challenge was removing the filter w/o spilling a drop.
The vacuum tank was ready to use soon as filter was loosened a few turns to leak into small tray first.
Then transferred along the bilge till access near front of engine.
If tray is secure under filter,
the standard process for these GM filters is punch a hole with long narrow screwdriver at the side bottom edge,
and let it drain completely before cracking it loose.
Vacuum tank removing the bulk of oil, so if tray does get loose, it's not a mess.
Now the filter is clean/oil free with actual grip to handle it.
This process is from servicing fleets of trucks, when making a mess is not really necessary.
Engine can be filled with oil while this process in under way.
I'll be ordering the re-location kit before next oil change from Summit Racing.
Here's the post & process used.
