Default Tension Pulley assembly.

Fellas, how hard is it to change the tension assembly on my 90 Vette. Mine is starting to rattle so I bought a replacement from National Auto. I have seen a tool for sale in the cataloges to get at the part. Can it be changed with a ratchet and ext.? Or should I let it be changed by a pro? How long and hard a job is it ? Allentown Ernie

I'd make sure it isn't the belt first.

About 5 minutes. Use a 1/2 inch breaker bar to relieve tension. Unbolt and slide back the Tensioner with the bolt. It usually hits the crossbar, but it comes out with the bolt inside the Tensioner.

It is a 5 minute job.
