740 RSR: Why do I have two relays but no electric fan? 700 1991

740 '91 sedan, auto, all original, mint condition 100K, REX/Regina


Following a recent repair on idle and startup (Thanks Lucid and Aleekat), I am wondering why I have two side-by-side black RSR-like relays on the engine compartment when the car has no electric fan.

Reading the FAQ, it seems when there are two, one is for the injector power and the other for elec fan (my fan is belt/clutch operated, no fan for A/C either).

When I repaired the idle/startup problem, both relays were in need of resoldering, and the symptom was such that most of the time the pump would not run when cranking.

After resolding those two relays, all is 100% fixed, including the idle problems when the car was actually running.


Anyone have this setup or have any idea?


Thanks in advance,
Greg
