: Couple of new issues, going to dealer soon, any hints I can give them?

1) Something I've been noticing but seems to be getting progressively slightly worse. When I'm moving at minimal speed (just enough off idle to move the car) and sometimes sitting at a stop-sign or light while in gear (goes away if I switch to neutral) there's a harshness or rough feel. I have a slightly inclined driveway that I usually back into for parking and this is where I notice it most. I'm thinking some sort of torque converter issue, but not sure. Anyone else have a similar problem?

2) When the car is cold, and especially when it's cold outside the engine makes a chirping sound. Could just be something simple like a serpentine belt adjustment but it's a new thing and just want to be sure to address it if it is a problem. Also, almost sounds like it could be a slight exhaust leak.

What is the service interval for the serpentine belt?

Car is a 2005 V8 with ~65k on it. Still under CPO warranty.

I normally replace my serpentine belts at around 50K as a precaution. You can check the belt for wear or cracks. Don't know what the manufacturer recommendshttp://www.cadillacforums.com/forums/images/smilies/thumbsup.gif

PLEASE CONSIDER THIS !
If you choose to change the belt , under your controlled conditions=lowest price
Having to change your belt, because it failed on Interstate= towing,delay in your time, tie up car schedule for belt replacement= sucks.
Having done it in advance, with NO delays=PRICELESS

Have a GREAT Holiday everyone. :cool2::cool2:

I'm not concerned with the cost of replacing the belt, just hadn't seen the service interval on it.

Any ideas on the roughness issues at/near idle?

Change the belt & save the old one. You may never need a third.

If the chirp persists, I'd suspect the tension pully. Does it always ocurr? If so, you can run it briefly without the belt asnd eliminate the water pump, alternator & power steering pump as well.that whole system.

MEMBERS, PLEASE POST IF I'M WRONG!

It only seems to occur when the car is cold and it's cold outside. For instance when I use remote start in the morning before heading to work.
