BodybyFisher Posted July 9, 2008 Report Share Posted July 9, 2008 I need to replace my front engine mount, I can feel the engine rock on acceleration. I replaced the left mount when I did the ISS sensor. Has anyone done this job?

Cadillac Jim Posted July 9, 2008 Report Share Posted July 9, 2008 Be sure that the torque dogbone bolts are really tight. I see you replaced them last year. When I did that, after awhile the engine would rock and I found that I didn't tighten the bolts enough. To hold properly, they need more torque than a good tightening with a 3/8" ratchet. I went to a 1/2" ratchet and a really good tightening and that did it. The torque is 44 lb-ft (FSM page 6-47). The first step in changing the motor mounts (FSM page 6-46, where your picture came from) is removing these anyway. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

KHE Posted July 9, 2008 Report Share Posted July 9, 2008 I need to replace my front engine mount, I can feel the engine rock on acceleration. I replaced the left mount when I did the ISS sensor. Has anyone done this job? In a way, I have done that job... When I Timeserted my '97 STS, I couldn't get the engine back in the car with the front mount attached to the engine. I removed the rubber mount, got the engine in the car and bolted to the trans. I then used a jack to raise the engine - a piece of 2x6 works well to spread the load across the oil pan. I raised the engine enough to obtain the clearance to install the mount and then lowered it into place. You'll need to remove the dogbones prior to starting the repair, mine were already off due to the engine R&R.
