Cracked Cylinder Diagnosis: Remove the Compressor

DOUG JENKINS: Hi. I'm Doug. I work with 20 great guys in St. Louis at Doug Jenkins Custom Hot Rods, and we're going to do some work for you today on Expert Village. There's no real right or wrong order when you're trying to get an engine torn down. You just take the things that are obvious, the things that are on top, the things that are in your way, and get them removed. So he's getting one of the brackets out of the way. That's the idler-pulley bracket, the tensioner-pulley bracket that he's getting out of the way. Now he's just got a couple more bolts in order to get the compressor completely out of the way. There's usually just one wire attaching a compressor circuit. That wire operates so that when you hit the trigger on your A/C, it turns the clutch on for the compressor. So we were fortunate, with this installation, that there was enough hose to lay the air-conditioning compressor off to the side there. Don't be tempted to just take the A/C lines loose and let the refrigerant blast into the air; that's just bad form.
