2001 CHEVROLET BLAZER V6 4.3 Liter F

Hi jftsdt! If you have to ask you are probably going to find it a bit daunting. You need to sit down with the Chilton's manual for your Blazer and see what it takes, step by step, to get through the job. That will give you a better idea of whether or not you want to take the job on and whether you have what you need to get it done. You will most likely find a copy of the Chilton's for your Blazer in your local library but if not you should be able to find one easily at your local bookstore or parts place. Good luck!
