What kind of tools do you need to remove the oil cooler lines and is there an easy way to remove the oil cooler lines without taking off the radiator?

 

To remove the lines from the oil cooler end you need small pliers to pull the wire clip out of the slot ( C shaped ) then the connectors will pull stright apart . They may be hard to pull apart, do not drop the rubber 0- ring in each .

 

yep yep, they are held on by quick disconnects, youy actually only need a small screwdriver but a needle nose pillers will work
