1995 E300 belt tensioner questions

[freesoul]

Greets,

Horrible squeal that developed that I am 99% sure is the belt tensioner.

My question is should I replace the pulley only, or also the tensioner arm and shock? Belt is a no-brainer....

If the pulley makes noise when you spin it, replace it. If the tensioner arm wobbles about the big bolt into the engine block, replace it. If the tensioner arm clicks are you rotate it around the big bolt, replace it.

There is a big washer between the tensioner arm and the block. Make sure you transfer that washer to the new tensioner arm.

thanks dude, I'll just return whatever parts I don't need.

You'll need a 17mm Hex to remove the pivot pin that attaches the pivot arm to the timing cover.

I'd check the roller pulley out first. Hows the AC running?

AC works great, at least until I go through a car wash it runs warm for awhile but I believe thats due to a leak (windshield was just replaced and the glass is crappy which leads me to believe it was not sealed correctly and moisture is getting in somewhere but thats another thread )

thanks for the tip on the hex wrench!
