Timing belt or chain
wanna do some maintenance on my ´07 Grand Caravan 3,3l (121000km) before winter comes. I have absolutly no experience with Dodge (is my first one) and i wondered if that 3,3l has a timing belt or a chain.
If it has a belt,..., what it the changing interval by miles/kilometre´s?
If it has a chain,..., is it maintenance free?
Thank you for answers.
