I have a '98 Z3 that is still a great car (will be for sale in after the snow stops) but I could not resist a georgeous '01 Z3 3.0 with 27,000 miles on it. I have decided to change the belts and hoses and am wondering if you have to take off the intake manifold to access the hoses?? If so, how tough is it and what are the pitfalls??
