2003 TL. How do I remove the oil pan? - TL Acura Cars & Trucks

Not too hard if it is a southern car, if it's from the north, a bit more effort might be needed because the nuts on the exhaust rust. If you are working on the ground, get it up high on ramps or jack stands. Always put another support under the car. Leave the floor jack in place and use jack stands, slide something, like the front tires, under the car, too. NEVER work under a car without a backup support. Cars can, and do, fall off jack stands.
1st you have to remove the exhaust "A" pipe. 3 nuts, 14mm on each exhaust manifold need to come off. ALWAYS spray a penetrating lube, like WD40, on any exhaust nuts before loosening, and before installing them. You need a really good socket, extension and a breaker bar, make sure the socket is on the nuts correctly, break them loose without rounding them off. Then two 12mm nuts on the support bracket, and 3 14mm nuts at the outlet of the "A" pipe at the converter. If these last 3 are too rusty, you can unhook the exhaust hangers and move the assembly over. (Leave the back muffler hangers on.) Drain the oil. (I always try and do these jobs when an oil change is due) two 14mm bolts going from the oil pan to the transmission, and a 10mm bolt holding an access plate at the transmission end, remove access plate. Now a bunch of 10mm bolts and nut holding the oil pan in place. You might have to pry the pan loose, a big drift works good. There are a couple of spots to hook onto and pry.
