Too frequent coolant changes? Toyota recommends 60,000 miles to replace
coolant. If you read waht I wrote, I go double that. I wait until it
starts to look cloudy or the temp guage doesn't sit in one position
anymore. Toyotas have very good cooling systems and will almost always be
just below the center of the guage. If it fluctuates from that, it's time
for a change, 120~150,000 miles.
There is no recommendation for brake fluid. I figured, like I said, you
would be baiting me, so I checked all the Toyota maintenance schedules I
could find, and none of them had a brake fluid flush or change. The best
mention was, "Top off all fliud levels."
So, according to you, my changing the brake fluid occasionally goes
*against* the manufacturer's recommendation, so I guess I'll have to stop
doing it...
However, I did learn something else: differential gear oil should be
changed every 30,000 miles. Guess I know what I'll be doing with my Supra
this afternoon!
