Cool oil filter and drain plug location

hey there, just got my new 06 tb'r. also just set up this account and don't plan on being a newbie for long....so....just wandering where is the oil filter and drain plug on these I6'S. I see what looks like an access cover underneath the engine in the middle, but don't want to start messing with things until i'm for sure. please advise. THANKS.

That's the place. Once you open that you will see the plug and you will need to reach up into the opening and the filter will be on the passengers side of the engine. The first time you change it you may have a tough time getting the factory filter off as they really tighten them to tight.

Welcome and hope you enjoy the new ride!

thanks, i will check it out. will there be enough room to get a filter wrench in there to loosen the factory welded on filter. the way i usually do it is with a ratchet, breaker bar, and a socket style wrench. thanks again

You can use an old style filter wrench but it's tight. The socket style wrench with a couple long extensions works the best for me. It is easier to have the vehicle on ramps - I've done it both ways.

When I did mine the first time I used a socket style wrench with a socket handel that had a pivot on the head so I could angle it down and long handle to get a good turn with. I have never had mine on ramps to do this but I can see where it would make it easier but not necessary.

Definately not neccesary to be on ramps, but for us old geezers it's sure a lot easier.

especially about the oil everywhere part, though I've seen oil filters in worse places than the TB. Yeah, each change does get easier. One member said a while back that he takes his drill and drills a small hole in the bottom of the filter and lets it drain for a while before removing it. I just turn the filter a couple of turns with the socket wrench and give it a few minutes to drain in the pan.

It is messy, I've tried placing a large ziplock bag around the entire filter to catch the oil as I spun the filter off, but I still made a mess. I like the sound of drilling a hole in the bottom of the filter to drain it before removing it.
