The best way to find out is go to your local library to borrow or auto parts store to buy, ask for a haynes or chiltons manual on your vehicle. This will tell you everything you need to know about working on your vehicle. Not a fun job, takes time and alot of patience. This really doesn't give any information on how to do the job but where to get the best source for good information.
