Hi Guys,
I just changed my belt for the 1st time on my 04 v6 4x4 4runner at 150,257 miles. It didn't look like it needed to be changed once I got it off but now I keep it as a spare. I don't know if aftermarket ones will last as long so I bought this replacement from the toyota dealer. On a side note I didn't change my coolant until the same mileage and the color of what I drained and filled looks exactly the same even though I drained it six times. Seems strange.
My next task it to change the differentials and transfer case fluida soon since it has never been done. I will try to post a picture when I am done.
In my opinion, this vehicle is very stout and overbuilt compared to most. I still haven't had any mechanical problems and still have original battery, alternator, rear brakes and all interior and exterior lights.
