Sweet ride. I'm trying to find a slow coolent leak on mine. Changed the expansion tank (nothing wrong with that) and upper and lower rad hoses just because of age. Still not corrected. So many hoses, so many days...sigh... At least I'm learning yoga by trying to remove those seven torx screws holding down the back of the CCV!
