My philosophy is that in replacing a part that has lasted for some time it may get replaced by a part that soon fails.
In addition, the act of performing PM by replacing parts that have not shown any sign of a failure mode introduces a potential failure mode just by performing the PM. As 180 stated in an earlier post ..."why change something that isn't broken?"
I used to have a 1993 Suzuki Swift GT. Most reliable car I ever owned. I owned the car for 20 years and never changed the coolant or thermostat. I checked the coolant every couple of years to see if the coolant was still providing protection. If the tester read good, that was good enough for me.
