Coolant change after four year mfg date

[haigha]

I posted a few weeks ago that my 04 4.4 X5 is out of warranty soon (Oct. 28).

It has about 17.8k miles on it and four green bars on the service lights.

I am taking it in for the final oil service under the service agreement before the warranty expires.

One thing that my service advisor told me last fall is that there is a covered coolant change as part of the service agreement four years after the manufacturing date even if it is not due for one by the service indicator lights. So I've asked them to do this. When I called today, the new service advisor had to talk with the service manager to confirm that it is the case. I thought that the information could be useful for other low mileage owners (especially with C$45/gallon post I just saw)

Note that you need to do the coolant change between the day four years after the mfg date and the expiration of the warranty for it to be covered.

Does anyone else have an ideas on what to ask them to check before the warranty expires?

Any service bulletins?

Thanks.
