RE: Audis vs Batteries
On page 19.8 of the Bently manual, it states:
The radiator fan circuitry can be modified to improve hot starting
characteristics by reducing underhood engine temperatures during
high ambient temperatures. An additional time relay, wire harness
and thermo-switch are installed.
Whenever the underhood engine temperature is above 90 degrees C
(194 degrees F), the thermo-switch will close and activate the time
relay. As long as the thermo-switch is closed and the engine is
shut-off, the radiator fan will operate for a maximum of 10 minutes.
The manual indicates that this is for models from January 1986 until at least
1988 (that's the latest that my manual covers).
Wow! Hadn't heard of that one before. *10* Minutes! What fan speed setting
does this run at? I would presume this is mostly a "summer" operation, and
thus presents less of a problem to winter/cold-start/weak battery? And I
thought my UrQ's "injector cooling fan" was a krock . . .
