BodybyFisher Posted March 12, 2010 Report Share Posted March 12, 2010 Im changing the accessory belt on 97 deville 4.6. The 1/2 inch braker bar was too big. Does anybody know what size breaker bar I need? The correct breaker bar is 1/2", here is the instruction from your service manual: Install a 1/2 inch drive extension into the belt drive tensioner (6). Push down on the extension to release tension. Remove the drive belt from the power steering pump (1). Slowly return the tensioner to the original position. Remove the belt.

Ranger Posted March 12, 2010 Report Share Posted March 12, 2010 The water pump tensioner is 1/4", but you said "accessory" belt. That's 1/2". Link to comment Share on other sites More sharing options...

Very good point Ranger, I immediately moved to the serp belt that was 1/2" and assumed he did not see the notch Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

It was dark when he was helping me and he said he tried the 1/2 inch and said it wouldn't fit. Guess I should have tried it myself. Thanks.
