Dodge Durango 2004 Limited (Hemi)

Anyone have a service manual for this SUV or a link to one that we could check out online? Ours needs a to have spark plugs and the PCV valve replaced, and the shop wants to charge us $200 to do it but my husband is pretty handy and I think he could do it if he had a diagram of where the parts are located. We're a family of five on one main income right now, so any work he can tackle himself is definitely worth doing!

Thanks for the help!
