One problem related to engine belts and pulleys has been reported for the 2005 Chrysler Town & Country. The most recently reported issues are listed below.
Noticed a grinding noise in engine at 4,000 miles. Took in for the oil change and mentioned to the service advisor that there was a noise. After 3 weeks in a rental car, they finally returned the van after replacing the following: cylinder head, valves, cylinder head gasket, intake manifold gasket, 3 pushrods, rocker arm, and an air conditioner belt. Not more than 8 hours later, I returned the car with a new noise. This time they replaced the intake manifold and gasket as they were improperly installed by the mechanic. Finally back in my own car after another 2 days.
