2005 kia sorento lx
used a new code reader and it shot me the crankshaft sensor high input code. im at 147000 mi. so im wondering if its just better to let them do timing belt, water pump and crankshaft sensor all at once. without the manual, i have no idea how hard it would be just to do it myself. i work alot and have had 3 back surgeries, so i dont need to over do it. is the crankshaft sensor something thats easy to get to or will i have to rip apart front end? thanks for any help.also, does anyone know what they are charging for all of of this to be done at dealership?
