" Hello, I'm Mark Blacker with Expert Village. In this segment were going to discuss removing various items so we can replace the defective hose. In a lot of today's automobiles, everything is very compact and very confined. Sometimes we'll find it necessary to remove various components so we can gain accessibility to the other components that may need to be replaced. In this case the first thing that we need to remove is this air intake booth. Our heater hose that we need to replace is mounted under the thermostat and wraps around in back of the motor below the intake that connects to the heater control valve. So to get accessibility to that, so we have a good visual access to it and we can get our hands and tools in it, the first thing we'll need to do is remove this air booth. This is done by loosing two Phillips screws on each clamp on each end of the hose and removing the clamps that clamp the various other hoses to it. In this case the clamps are held together with a Phillips screw. We'll just simply loosen that screw up. Remember righty tighty, lefty lucy. After we loosen both those clamps, we'll simply take these other hoses that are connected or held in brackets to keep them held firmly in place so the don't vibrate and cause damage, or have damage caused to them. We need to pop them out of the little clamps. The rubber clamps on the booth and then there is one other clamp I see that's a spring clamp. This will require use of a pair of pliers. There several types of pliers you can use to release the spring clamp. I prefer channel locks; hey give a good angle and a good bite. You just want to clamp down on that spring releasing the pressure expanding it, sliding it down the hose out of the way so you can simply remove that hose, then remove the other hoses out, and remove the air tube one end at a time, by wiggling, slowly sliding it off the two ends. Remove any other vacuum hoses that may be attached. In this case we have one vacuum hose attached on top. Pay attention to the ones you removed so you know where to replace and where they are located. Now we just simply set this out of the way. Please watch our next segment and we will show how to remove the other items to gain complete accessibility to the heater hose."

on 11/27/2008 Hi Mark,
Thanks for the great video(s). I actually was only interested on removing the air intake boot (and of course of replacing it).
I have a 1999 mazda protege, which is a little simpler to remove compared to the video.
FYI I just saved about $150 in fees and about $60 in parts. I bought the part which was about half of why the mechanics wanted to charge for it!
Thanks Gerardo
