Best advise is to buy a haynes manual. I have a 97 jimmy and it's the same one for your blazer. That are about $20 at an auto parts store. I changed both on mine, idler 3 times. It has pictures and instructions. I've had my manual for years and it's almost destroyed. I'll just buy a new one! It has saved me thousands in shop fees since I bought my truck in 2000!
