2008-2020 Dodge Grand Caravan Maintenance and Cost
The 2008-2010 Grand Caravans with the previous-generation V6s are very sensitive with regards to maintenance, and skipped services will lead to all kinds of problems. On the OHV 3.3 EGA and 3.8 EGH engines, oil changes should happen every 6,000 miles, but this should be reduced to 5,000 miles or less in severe use, such as when towing or in dusty or sub-zero conditions. The bigger 30,000-mile service should cost about $240 at an independent shop and $430 at a Dodge dealer. Both the spark plugs and their wires should be replaced every 100,000 miles; this service should amount to $1,030 at an independent shop and $1,380 at Dodge.
Next up is the 4.0-liter EGQ SOHC engine and although the lube-service interval on this is also 6,000 miles, experience has shown that this fragile engine requires oil changes at half that distance to offer proper long-term reliability. Its other service requirements are as per the 3.3- and 3.8-liter engines above, except for the recommendation to replace the PCV valve every 30,000 miles and the timing belt at 100,000 miles. Replace the water pump at the same time as the timing belt to save on labor. The 30,000-mile service, including the PCV-valve replacement, should come to about $415 at a shop and $655 at a Dodge dealer. That 100,000-mile service is the big one, of course, and it should cost around $2,050 or $2,620, respectively due to the timing-belt job.
The 3.6-liter Pentastar V6 used from 2011 has a better design for the lubrication system and can keep going for hundreds of thousands of miles with oil changes every 5,000 miles and with no special treatment. It also has a timing chain that requires no maintenance if oil changes are adhered to. The PCV valve should be replaced every 100,000 miles.
The cabin air filter must be replaced every 12,000-15,000 miles, depending on which mile multiple of minor service corresponds with your year model. Air and fuel filters on all engines must be replaced every 30,000 miles, and spark plugs on all engines last 100,000 miles. Given the fact that the six-speed automatic 62TE transmission has a constant trickle of failures every year, it is critical to replace its oil at least every 60,000 miles and preferably sooner.
