Just hit 100k miles on my 05 and have to say i love this Hemi ive had it since it was new and over the last 6 year have had absolutely 0 problems with my truck. Is there any suggestions on preventitive maintenance i should be doing? there are no funny noises or lights on my dash it runs like its new but would like to be proactive instead of reactive. Thanks

 

Well, you're long overdue for a set of plugs, the tranny and diff fluids are long overdue. Also, clean/replace the PCV valve. Clean the throttle body. Plug wire are due soon if there are any. A coolant flush may be in your near future. The O/M can provide some fun things to do.

 

Change your plugs, all fluids don't forget the forgotten fluids like differential and power steering. Have you ever changed the hoses, belts, thermostat? All simple piece of mind items id do, now of your on top of all those items kudos. My worst fear is waterpumps is do them for piece of mind too.

 

You should look in your owners manual which states all the reccomended maintenance schedule. here are the main things you should be concerned with;
oil changed every 3-5kmi
air filter every 2-3 oil changes(10-15kmi)(PCV valve in conjuntion with air filter)
Serp belt every 50-60km(allows you to check pulleys for bearing wear and premature failure(pulleys should NOT free spin or make any noises)
plugs due every 30kmi
diff fluids due every 15-30kmi(15 for towing, 30 for highway)
transmission due every 50kmi(filters due 100kmi)
coolant due 36-50kmi or every 3-5yrs
power steering due every 50-60kmi
Brake fluid flush every 50-60kmi
