2011 mitsubishi Endeavor 3.8L
The serpentine belt that runs the A/C, alternator etc. Is loose.
Is the tensioner adjustable or spring loaded and how do you get at it to replace it?
If that belt is loose there's a problem and I wouldn't drive it until it's fixed , not sure what you have to remove to get at it but that's how they make them . It may be the easiest thing in the world . A tensioner pulley bolt may have a left hand thread .
The whole tensioner has to be changed, doesn't it? The pulley seems to be fine.
