I recently purchased an 04 XC90 2.5 FWD with 101k on it. I want to learn how to fix the majority of mechanical problems it may currently have or will have. I was wondering if there was a knowledge base or website that had diagrams or something along those lines. I havent ever repaired any cars before but I'm a quick learner and feel like this a necessary skill I must obtain. Any help is appreciated!! Thanks and Cheers!!
