Ribbed heat exchanger and other changes (CA only)¶
In order to insure that the heater output meets the requirements of extreme climactic zones the heater system has been changed.
The engine heat exchangers are finned
The hot air fan has a two stage switch:
First stage (current draw 70 Watt)
Second stage (current draw 160 Watt)
The two stage switch for the fan operates automatically. The first stage is limited to stationary heating operation. The second stage is automatically switched on when the engine is started (voltage at regulator swicth D+). This ensures that the current draw is limited during stationary operation.
Service installation into previously produced vehicles is not intended.
