My wife has a 2006 Sedona (first year of the new chassis) with the 3.8L engine in it. It has 52k on it and the maintenance schedule says to replace the timing belt at 60k. However, by looking at the engine it looks like it might have a timing chain. If there is a belt, it looks like one would have to pull off valve covers and such. Does anyone know if the 3.8L engine has a belt or chain?
