2003-2006 3.8 Timing belt and heavy maintenance list. Just a reminder for everyone 100k /60k or 5 years for the first belt depending on where you live and what year truck you have and then 60k or 5 years.. Does not matter if you went 20k in the 5 years do the timing belt service the rubber cracks and dries out. Coolant in most cases is on a shorter cycle. Plugs are 90-100k
