When do you change out your coolant? My car has 32,000 on the odometer and I have never done this on this car.
I recall the same for the service interval.In the past, the interval stated that the factory fill should be good for 10 years/100k if my memory serves me correctly. After that it was every 5 years/60k.
Correct, lots of shops use vacuum to fill the cooling systems on newer cars. I cannot speak for the V6 owners, but my K24w was very easy to burp air out of the system using a coolant funnel. Previous cars I've owned are not in any way easy, G35/350Z's the heater hoses run up and over the engine block, thus causing air-lock problems which can be difficult for those new to the cars.They do it when you get the timing belt/water pump/tensioner service. Not sure if the V6 is easy to burp the air out. These days they have a device to evacuate the air before adding coolant.
