its right behind the engine mount, so you cant do it any other way. dunno why you're scared to remove it since its really easy!
undo top fixing from the mount, jack engine up till it lifts off the mount. remove 3 starter motor bolts and smaller bolt holding metal coolant pipe to bracket and it comes right out. remove bolt holding crank sensor in then swap, easy.
clean out the crank sensor bolt head and tap the tool in with a hammer to ensure its all the way in. good spray with proper penetrating oil might be an idea too
