In this segment I'm going to cover removing the radiator hoses. Prior to doing that, we want to remove that pan that we just used for draining the automatic transmission fluid and reinsert the pan we used to catch the antifreeze. We'll open up the petcock at this time to remove any more that might have run down from the engine block into the radiator, drip out. Inevitably, we'll remove the upper and lower hose and we're going to get some fluid loss there, so we want a pan underneath the vehicle to catch it. There's three hoses we need to remove, the upper hose, the lower hose and the bypass hose. We'll start with the bypass hose. It's just a small spring clamp, we squeeze it, and slide it down the bypass hose a little bit. Once again, we want to twist it back and forth to break it free. Once we've got it broken free, we just grab it and slide it down. We just disconnect that and slide it off. The upper hose is a big spring clamp as well. We just want to squeeze it, twist it back and forth, slide it down the hose, off the nipple. By twisting it back and forth, we're going to try and get that to break free. Once we've got the hose to break free, just gently twist it around. Just go ahead very gently twisting back and forth, sliding and wiggling, until we slide the hose off. We're just going to fold it up, back out of the way. The exact same procedure for getting the lower hose off. Just squeeze the clamp, slide it back on the hose, wiggle it back and forth until the hose breaks free, gently slide it off the lower fitting. Be careful because your liable to loose some coolant at the same time you pull that hose off. Please watch our next segment where we'll cover removing the electrical connector.
