I just changed the oil for the first time on our 2010 Liberty. What a pain in the A _ _ to get to! Why would anyone design something that makes a routine maintenance item so hard to reach?!? Anyway, after several attempts with filter caps, filter wrench, etc. with no luck, I used a strap wrench that attaches to a 1/2 inch drive and with about 15" of extensions going fron under the radiator at about a 30 degree angle, I finally broke it loose. It was extremely tight but the oil drain plug was almost loose enough to turn it with my fingers!!!!!!
Go Figure! There's also no way to get the filter off without making a mess so you better just have plenty of rags around! Also, since the filter goes on at a steep angle, you can't really pre-load the filter with clean oil. Therefore, the engine runs dry for a few seconds. Mine made audible clicking noises for about 3 or 4 seconds, until the oil started circulating. Anybody else experience this? And another thing; any comments on the reason for using such a light (5w20) oil? That stuff poured like water! Seems awfully thin to me. Comments?
