560SL (107.048) V8-5.6L (117.967) (1989)
Coolant Temperature Switch [S25/5]
Low Speed:
-
Low speed with high pressure switch (S32) instead of temperature switch (52°C) known previously. The switch engages the relay K10 at a
refrigerant pressure of approx. 20 bar and the low speed via preresistor (R15). It disengages at approx. 15 bar.
High Speed:
-
High speed is directly activated with battery voltage by means of temperature switch (S25/5) at 105°C coolant temperature via relay (K9) and off
again at approx. 97°C.
