What' included in a tune-up?

On a 2014 Hemi with 129,741 miles. No past record of service, what should a tune-up consist of?

If you have a owners manual, browsing through may give you a good idea. I thinks its basically plugs, ignition wires, filters, PCV valve, oil change. Perhaps coolant change. Perhaps serpentine belt replace. Check alignment, put air in the tires

"tune ups" went away in the 80's and were replaced by scheduled maintenance. If you don't know what was done, then you'll want to do everything required up to 130k miles - so all fluids and lubricants, plugs, filters and so forth.

You know what I didn't even think of that. Thank you.

I knew this but when the dealership service guy uses the term, I guess it can make you second guess yourself.

Yep, the same way people (and dealers) use the term "that'll void your warranty" when they really mean "that will cause the manufacturer to deny warranty coverage on that particular failure".

Like ColdCase said, the manual tells you what maintenance is required. Just do everything up to 130k miles and you'll be fine.

Oh, and you probably want to find a good local indy to do the service. The dealer will nickel and dime you to death.

You should also check you brakes. It is possible the you are still running the original pads. I changed my disks and pads at 115k miles because I was experiencing a slight judder when they got warm on long descents. What surprised me was the pads were only half worn at the most, however the front disks were only 0.5mm from the minimum thickness.

You should at least check the pad wear and that both pads are making full contact with both sides of the disks. The brakes use a sliding caliper and sometimes the pads wedge or the slider pins corrode resulting in one pad wearing faster than the other. This is more common if you use your car in wet or cold regions where they salt the roads.

You may also consider refreshing the brake fluid. I have not heard of an specific issues with Jeeps but I have seen ABS modulator failures on other vehicles as a result of contaminated brake fluid. The replacement is very costly especially considering the cost of a fluid refresh.

A brake flush is a "must" not a "consider".
