Yeah, but with the after-run keeping coolant flowing through the turbo
and radiator fan blowing, the turbo's internal temperature should be
kept in check, eliminating the likelyhood of oil coking... (that is,
if we could get the after-run to actually activate after each shut-off
by having more reasonable thermoswitch kick-in temps).
