Turbochargers operate at high temperatures. The Cool Down Timer is
designed to keep the engine running when the ignition is turned off to
prevent turbocharger bearing failure that could occur when the engine is shut
down, stopping the cool lubricating oil flowing to the turbocharger while it
is still hot. If the oil flow is shut off too early, the remaingin oil in the
bearing housing will overheat causing coking of the bearings which causes
both premature bearing wear and reduced oiling of the bearings. Allowing the
engine to idle to a minimum operating speed gives the turbocharger time to
cool down. The CDT works with any K-Type EGT probe commonly found in most
pyrometer gauge kits.
