Since my mileage is getting up there, should I think about maybe buying a water pump, starter, alternator or whatever before the Trump tariffs price increases kick-in in January? My experience with other vehicles is that around 100,000 miles the accessory systems start to wear out. Is this true for Rams?
If you're going to keep your truck long term, then use this 100K-mile benchmark to do the required maintenance and servicing.
I don't know your service and maintenance history, so here are some recommended ones at this mileage to consider.
- transmission fluid & filter, and if applicable look at also installing the
@caulk04 transmission cooler bypass upgrade. Dropping trans temps in the 30C rage is a huge bonus for our trucks (use either MOPAR or Valvoline MaxLife fluid).
- spark plugs: Rock Auto is a very reliable source. Look at the NGK Ruthenium HX plugs.
- coolant flush and fill (MOPAR coolant is recommended).
- retorque all your intake manifold bolts as they are known to back off and cause drivability issues.
- full throttle body service. Remove it and give it a really good cleaning and with the age of the truck, purchase a new OEM gasket, too.
- remove the PCV valve and either thoroughly clean it, or just replaced it altogether.
- remove the serpentine belt and thoroughly inspect it & replace if required. At the same time while the belt is off, check for play and abnormal noises in the idler and tensioner pulleys, and water pump, and replace if needed.
- brake fluid flush & fill, and a good front & rear brake service, too.
- I'm uncertain if you have hydraulic power steering or electric. If hydraulic, perhaps a fluid swap is in order.
- front & rear diff fluid change, as well as the transfer case if you're 4X4.
This is like the full service catalogue for a 100K service............
