    Just about every car repair I've done, I thought I was over my head. They all worked out fine. You'll be ok.

    The thing about anti-seize is it will allow you to over tighten and break them, if you use anti seize do not use factory torque settings.

    Any time I do a new repair I have never done I always get a llittle hesitant for some reason. I've got skilled friends to help me out if I get stuck anyway.

    Haven't had any issues yet with anti seize on exhaust bolts just makes it easier to go on and off as long as they are on tight and prevents rust. Just a personal preference.

    Agreed good product but an inexperienced person with tighten until it snaps.

    Like some headbolts, the torque is different for oiled threads and dry threads.

    I have a friend at a shop that was working on an explorer that broke a manifold stud off, at the end of the day it was cheaper and easier to swap engines, and it is an exhaust shop in business for many years. The customer did not want them to fix the stud so they took it to another shop that messed it up and drilled the head off center then it came back, at that point they could not fix it and out came the engine.

    If you get into trouble ask for help before you make it worse not after lol

    Re: Motor Mount change difficulty

    I searched around and did not find a post from anyone who actually changed the motor mount on a V8 SRX so thought I would add this.
    Just changed the left (driver's side) motor mount on my rear wheel drive 2005 V8 in my driveway using some ramps. I was back in the house and showered up in under 2 hours.

    No need to remove the exhaust manifold I only needed to bend the heat shield up a little to get to the top nut and used a 13/16 box wrench to take it off. I used a 13/16 deepwell socket for the bottom and removed the bottom nut on the right side mount (not sure if this was needed). BTW it's possible the correct size is 21mm.

    I used a hydraulic bottle jack with a 2 by 4 under the oil pan to lift the engine with it off centered towards the driver's side. I leaned the mount forward and lifted up and out to remove and replacement is reversed. I was quoted over $1100 for the job and I got the part for $120 so well worth doing myself.

    I am searching for aftermarket mounts for the 4.6L SRX. Were the left and right mounts the same? Pics would be saweet.

    I only replaced the drivers side #25971086 but each side has its own part number. I bought it from gmpartsgiant.com but you can just do a search using the part number once you have verified it is the correct one for your vehicle. Sorry I didn't take any pictures.

    Re: Motor Mount change difficulty

    Hey conedoctor. I recently took my 2011 Cadillac cts awd premium to a mechanic and had the motor mounts changed. Changing the motor mounts helped by not having a jump when I accelerate. I believe the mechanic was inexperienced with Cadillac's and now I have some new problems. I'm noticing different sounds when the car is at an idle or warming up. It sounds a bit like vibration at startup, and sometimes it sounds like a ball in a aluminum can a bit when the car is at idle. I believe it is an electrical problem, because when the lights come on at startup I hear a sound. The mechanic did say he was inexperienced with electrical automotive work. I can take it to sears and have them go over the mount changing process since they were the ones that discovered I needed motor mounts. Any thoughts? Let me know what you think. Thanks.
