I’ve had a bad experience recently when I let amateurs change the oil in my 93 LS. The person that changed the oil set the hood prop on top of the radiator clamp on the upper radiator neck, and closed the hood. Ouch! They cracked the radiator badly. What is funny is that the hood prop was just barely out of the clamp that holds it(they didnt push it into the little white clip on the left). Please make sure this does not happen to you. Watch that your hood prop always gets put in its proper clamp, I am also going to turn the clamp so the tabs dont stick up. I figured they should be able to handle an oil change.
