If you mean the engine oil cooler lines, it's pretty straight forward.You unbolt the adapter from the block and remove the "pipe" the oil filter screws into. Then screw the pipe right into the block and then the filter to that. Then all that's left is to unhook the lines from the radiator. A small amount of oil will drip out at first but no water as the oil pipe runs through the water tank but no water gets into it.
