Maintenance tips
Keep your truck eligible, reliable, and out of the shop with these basics.
Keep your service records
Warranty coverage requires proper maintenance. Keep receipts and records for oil changes, filters, and scheduled service — they are your proof if a claim is reviewed.
Take care of the aftertreatment system
DPF, DOC, SCR and DEF components are among the most expensive repairs on a modern diesel. Use the right DEF, complete regens, and address fault codes early.
Watch cooling and fuel systems
Coolant condition, water pump noise, and fuel filter intervals catch failures before they take out an engine.
Don't delay a diagnosis
A small covered failure can turn into a large uncovered one caused by continued operation. Get it looked at, and get authorization before repairs begin.
