I didn't have to on my 4x4 so believe you should have plenty of access for the 2wd but still may need to unbolt mounts and raise engine up to allow for oil pan removal.

Is it hard to replace the oil pump one you get the oil pan off?

Thanks Jim

Is pretty straight forward replacement. If slightly confused then look at the new pump to get an idea of how it works and replaces. Recommend getting a manual at the auto parts store before removal and read it thru step by step. Will want to be sure to prime correctly when do it. Very important to seal with seal or gasket properly so will not get air in oil. The oil pan reseal needs to be very clean and dry when reinstall at both the engine block and pan. Use quality gasket or seal such as FelPro. I like those the best but that is just my opinion.

They may be correct. The manual I suggested should be able to tell you for sure. I remember at one time that Ford trucks had to have the engine pulled to remove oil pan because of how low and back they were mounted for better center of gravity steering feel at front of truck. My truck is a V8 and with this being a V6 then may be set up way different so may need to pull engine but you can get second opinion or read the manual. Whatever you do, if you attempt then be sure which it is. If you attempt and get stuck and decide to take to shop and have to tow in because you have already removed some things they could charge more than the normal price because a tech remembers what he took apart and in what order so if you have partially apart they may charge accordingly.

Well I think your right, I need to get a Motor manual and a second opinion.

Thanks Jim
