Has anybody replaced the sparkplugs and coils in an LC200? I need to do mine and see the cooling lines are in the way for cylinder 8 (rear most cylinder on passenger side). I looked at the service manual online and can't tell if you need to remove the cooling bypass lines entirely or just loosen the bolts that secure them to the motor so they can be moved out of the way. Whatever it takes - it looks like a major pain in the butt.
