I'm hitting 110K on the odometer, but had the engine replaced at 40K due to a bent rod. When the engine was replaced (new one) wouldn't they have needed to change the timing belt? So technically I don't need the 105k service for another 35k?

 

As you say the engine was new, I certainly would think that they would use a new belt, but look at the bill to be certain as it should list all the parts needed during the install. If you can't see that it was replaced, you can eyeball the belt to see condition, or just get the job done if no documentation. Did they replace just the short block assembly and use your heads?

 

You've got to think they did, so your math sounds correct.

 

just double check with the dealer that did the install.

 

A timing belt is only $40, so I would hope they put a new one on since they had the thing apart anyhow.

 

If it was replaced with a new engine, I believe it would have a new timing belt, water pump, tensioners, etc and the timing cover would be in place.
