I need to get the new tires mounted on the SDL, along with an alighnment. I also need to change the coolant and brake fluid, and oil. This week I am going to finish the last of the mechanical work; which is changing the oil cooler line O rings and sunroof clips. When I changed the oil cooler lines 5 years ago I forgot to order new O rings so I used the old ones which looked to be in good shape. Well they are now starting to leak, but it worked for 5 years!
