Описание к видео GX470 - Always! Check pulleys when replacing serpentine belt Idler or tensioner pulley 4Runner

This GX470 is my latest project and while changing the alternator I noticed that the tensioner pulley was noisy. Over time it will get worse and worse so it's best to just take care of it.

You may not notice anything unless you check all your pulleys. Any time you have the belt off of the engine is a good time to check the pulleys. These pulleys could start to make a grinding or squeaking noise that could mask other problems. It's not likely that a pulley will fall off but drag and noise will increase over time.

This is just the pulley replacement, the tensioner is going bad your belt will slip under load. The tensioner is an assembly that includes the pulley and can also be replaced.
