Question type: Maintenance & Repair

This was just bought for my son. What kind
of maintenance, replacements or issues?

1 Answer


With the I6 engine?? Throttle body cleaning with fuses #10 and #28 removed are a must, and need to be done regularly once or more a year depending on driving habits/location. Put a fresh set of AC Delco 41-103's in it, this engine runs best with this plug. Don't do a complete flush on the transmission, only filter and refill with Dexron 6. Fan clutch tends go bad prematurely, but 08 has one of the better ones. Like every car, has a long list of quirks, but easy to fix.
