The FSM assumes a theoretically PERFECT factory condition (unmolested) vehicle, I have little objection in that case.
After 100K+ miles, and the typical mauling many of these vehicles have been through.
* Transmission wear factors stack up.
* Transmission thermal load rises.
* Radiator/heat exchanger internal efficiency falls.
* Engine wear factors stack up.
* Engine thermal load rises.
* Hydrostatic fan clutch efficiency begins to fall.
* Radiator/condenser have (unique to every vehicle) "blank percent" external debris under the AUX cooling fan and caught in the vanes/fins effecting heat exchanger efficiency.
* Alterations/superseded parts will impact thermal load. Example: Superior shift kit.
I can NOT trust any used car to be perfect.
