My car has two pans: one is the main upper pan and the other is the lower pan where the drain plug goes. The lower pan is what I am replacing and very accessible once you're underneath the car with bottom engine cover removed. All the bolts are there with easy access.
I was just wondering if it would be a good idea to clean whatever exposed parts once I remove the oil pan and what to use? Of course assuming there will be some kind of heavy oil deposits, but if I find everything looks good, then I won't miss with it.
