Improved Radiator Fan Switch
High engine temperature gauge readings (upper third of gauge) can be caused by a fan switch which switches at a higher temperature than desired.
Improved switches are installed as of Model 89. They can be identified by a production date of 2/8 (Feb. 88) stamped on the switch housing.
Switch PN 944 606 481 00: 924S, 944 up to 85/2
Switch PN 951 606 481 00: 944 85/2 up, 944S, and all 944 Turbo
The switch part numbers have remained unchanged.
Radiator fan switches with a production date prior to 2/8 (Feb. 1988) should not be used.
