I have a 2008 5.7L Aspen With 130k miles and bought it used with 97k and have no idea what has been serviced/replaced before.

What is the recommended mileage intervals for the Water Pump and timing Chain?
If the items need replaced, should I stick with Mopar (very expensive) or another brand?

Thanks.

 

If there's no clear issue, I wouldn't worry about it for awhile. There's no required (or even recommended) replacement interval for the timing chain or water pump on a 5.7 Hemi.
