The kid took a dip in the ditch a came away with about a 1 inch gash in the oil pan. He can weld the gash, but we are having trouble getting the oil pan off. Just how many bolts and how far (up into the engine) do we have to go to get this thing off?

Thanks,
Mom

You will have to remove any motor/trans mounts in the way and raise engine a few inches to get the pan off. Here are the instructions in the diagrams below to show you how to replace the oil pan. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

No rest or shut downs. If you hit the pan and lost oil, you may have seized the motor which will require replacement

try turning the motor by hand

Engine Mechanical problem
2006 Chevy Cobalt 4 cyl Front Wheel Drive 26850 miles

I am trying to loosen the drain plug in a 2006 cobalt and it was put in very tight by the last person who changed the oil. Since the oil pan is aluminum I dont want to apply too much pressure and warp the pan or the plug. What would be the easiest way to loosen it?

THere really isn't anything you can do other than apply enough pressure to loosten it. My concern is if the pan is aluminum, the threads may be stripped.

Let me know if you have other questions.
