Now that we have started a nice heat wave which should continue over the next days, I noticed that only one auxiliary fan up front is in operation with the A/C engaged (necessary these summer days). The A/C was topped up a couple of weeks ago and the system blows nice cold air inside.

When does the second fan kick in? Is it for the A/C or as an extra fan should the engine get very hot (not my problem) even with the viscous fan engaged?

This document is from the Model 202 Introduction Manual. I believe this function remained the same through the entire model run. Both fans should run, but in two stages.

Thanks mate! Just what I need to start looking around to be sure the fuses and relays are operational.
