timming chain?
 

i know the new four and the 3.3 ate chains but what about the new 2.7 v6 in the santafae .

2.7 is a timing BELT, not a chain. Who told you the 3.3 ate chains?

The "new 2.7 v6 in the santafae" is the Delta V6 Hyundai has been using for the past 10 years when they stopped using Mitsubishi 3.0 liter V6 engines. As jsinton pointed out, the Delta has a timing belt that is replaced every 60K miles. Early Lambda 3.3/3.8 V6 engines had trouble with faulty chain tensioners (which made a racket on start up), but I've never heard of an outright chain failure associated with this problem. The 4 cylinder Theta II engine has been very solid, I don't think I have heard or read about one timing chain issue with it.

sorry that was a misprint.iam not very good at typing.did not mean ate chains.i was thinking of buying a new sonata but not sure if i want a four or six.i have two an 03 with a 2.7 and an 06 with a 3.3 never had trouble with either one but changing the timming belt is rather expensive 0n the 03.

Not to hijack this thread, but...I recently purchased a 2006 Sonata with the V6. In the morning it's a bit noisier than when it warms up. Is this what you are referring to. Is there anything I can do about this? Thanks!

and then talk to the service manager at your local dealership.

Thanks for the info. Not sure how the warranty works since I just purchased this from a private seller. It has 29,000 miles on it. Thanks again.

All warranties remain in effect for secondary owners of Hyundai cars, except for the 10 year/100K powertrain warranty. That coverage is reduced to 5 years/60K, same as the 5 year/60K bunmper-to-bumper warranty. I will forewarn you that warranty coverage is predicated on a history of proper maintenance. Some dealerships interpret this as all scheduled services be conducted by a Hyundai dealership, others are more flexible. My dealer doesn't mind me performing my own maintenance for oil changes, fluid checks and tire rotations, but is insisting I bring the car in the major milestone services scheduled at 30K intervals which involves a coolant flush, tranny flush and a few other major items. 30K would be a good time to ask about the timing chain tensioners. Also, you should ask the previous owner where they had the car serviced.
