What should I do if my belt tensioner breaks?

What should I do if my belt tensioner breaks?

If you just put a breaker bar on it and push as hard as you can you can bend/stress the bolt. The proper procedure (since the tensioner is hydraulic) is to put pressure on your breaker bar and hold steady pressure and allow the hydraulic piston to push in.

Do you need a breaker bar to tighten nuts and bolts?

That’s it. The only thing it’s supposed to do is loosen (or, more rarely, tighten) nuts and bolts. Though humble, a good breaker bar is necessary to any mechanic or tinkerer’s tool kit. The way to find the best breaker bar is to assess the situation: how much extra leverage do you need?

What do you use a breaker bar for?

A: Generally speaking, a breaker bar is a non-ratcheting tool that is used in conjunction with sockets and wrenches in loosening fasteners. Also, they are typically longer than wrenches as the extra length enables them to provide the necessary amount of torque to loosen nuts.

Where is the belt tensioner located on a car?

Where is the belt tensioner located? The single belt loops around all the different pulleys on your engine, but one pulley has a tensioner arm, which will be the only pulley the has a square, 3/8-inch hole in the center. That hole is for a 3/8-inch ratchet nub, the part that holds the socket.

What’s the square opening on an auto tensioner?

Patented square opening feature: Use a bare 3/8 inch (9.52 mm) extension attached to a 3/8 inch (9.52 mm) ratchet with a cheater, or use a long handled “breaker/break-over” wrench, inserting it ( without a socket) into the square opening — General Motors (GM) vehicles have this patented method — in the tensioner lever or bracket.

What’s the hole in an auto tensioner pulley?

That hole is for a 3/8-inch ratchet nub, the part that holds the socket. Place the nub of the ratchet wrench into the square hole of the tensioner pulley and rotate the wrench. Try both directions, which will require you to flip the selector on the wrench to the opposite direction (so you can loosen or tighten).
