I have a 100k miles on my 09 Dakota V6 3.7L and haven't done any maintenance. What is the interval for spark plugs? Does it have a timing belt or chain? Is there any other maintenance I should do?

 

Plugs on the 09 are at 30K.

Timing Chain.

Maintenance schedule will be in your owners manual.

At a minimum, change out air filter, Coolant, trans fluid (And new OEM Filter), and diff fluids. Show that truck a little love man.

 

Hopefully, "no maintenance" doesn't include zero oil changes, brakes, or tire rotations. But, it sounds like you're due for the full package: changing all of the fluids (oil, coolant, differential, transmission, steering, brake, etc) and filters (oil, transmission, air, etc), changing the spark plugs (probably the ignition cables), cleaning and lubricating the brakes (front and rear), alignment, tire rotation, lubricating the chassis and suspension, cleaning the fuel system, etc.

Grab the owners manual and get caught up.

 

Thanks
