    Does the Chrysler 4.0 liter that you can get in the 2008 Town and
    Country and Dodge Grand Caravan have a timing chain or belt?

    Belt. That engine is based on the 3.5L v6, so it shares the same belt
    arrangement. The good news is that the 3.5 very rarely breaks a timing
    belt, even when people go past the recommended change mileage.

    The other good news is if the belt does break before the replacement is due
    on the belt. The lifetime powertrain warranty would kick in

    That isn't going to help people buying them used, which is going to
    affect resale value I would think - is this an interference engine or not?

    I have never seen a timing belt break on one of these vehicles due to
    mileage. This engine does not have a free wheeling valve train

    Its not freewheeling (the first-gen 3.5 was, but the 2nd gen and 4.0 are
    not). However, it really does appear that the belt nearly never breaks
    on these engines. Its sorta like the opposite of the Spirit R/T engine
    that ate a belt every 10,000 miles, I guess ;-) I've seen one 3.5L belt
    fail due to extreme neglect (well over 150k miles) combined with the
    water pump failing and chewing up the belt. But I've also seen a
    waterpump fail and the belt *not* fail despite getting smoking-hot on
    the seized water pump pulley. The engine started to overheat due to the
    stopped waterpump and the driver (my wife) pulled over before the belt
    or the engine was damaged.
