Can someone tell me how to remove those f***ing oil lines where they bolt to the bottom left of the engine? The ones for the cooler (as if there was others). I tried with one wrench, with to wrench and even WD-40. I just cant figure it out. Also, what's the sensor on top of th rad? coolant temp? I tought it was supposed to be at the back of the engine. S5 N/A.

 

Impact wrench and pray you don't twist the line off. I would get a can of penetrating lubricant as well.

 

How am I suppose to use an impact there?

 

Often what I do is soak the fitting down with PB Blaster, then use one wrench to hold the front cover fitting while I crank down on the oil line fitting with another wrench. The front cover wrench gets propped in position using a jackstand, piece of 2x4 or whatever is around (one end goes against the wrench handle, one end goes on the ground, support stands vertically). This allows boths hands free to lean on and slightly bounce on the cooler line wrench. After a few bounces it should loosen up. It's important to use good quality open ended wrenches, or adjustables with NO PLAY or the fitting will strip.

 

the sensor on the top of the radiator is the coolant level sensor.
