RREPLACING EXTRA FAN TEMPERATURE SWITCH Up to 1978 Models: Drain coolant. Disconnect wires and unscrew temperature switch. Installation: Replace seal. Torque values¹). Bleed cooling system - 17 00 039. ¹) See Specifications 17 00 039 | |
Testing: Connect ohmmeter (e.g. BMW service test unit M 06). Coolant temperature: < 92°C (198°F) = oo ohms. Coolant temperature: > 96°C (205°F) = 0 ohms. | |
From 1978 Models: Drain coolant. Pull off wires. Installation: Don´t mix up wires. Large flat male plug for extra fan speed I. Small flat male plug for extra fan speed II. | |
Unscrew temperature switch. Installation: Replace seal. Torque values¹). Fill and bleed cooling system - 17 00 039. ¹) See Specifications 17 00 039 | |
Testing: a) Stage I (large plug connections) Connect ohmmeter (e.g. BMW service test unit M 06). Coolant temperature: < 86°C (187°F) = oo ohms. Coolant temperature: > 97°C (207°F) = 0 ohms. b) Stage II (small plug connections) Connect ohmmeter (e.g. BMW service test unit M 06). Coolant temperature: < 95°C (203°F) = oo ohms. Coolant temperature: > 106°C (223°F) = 0 ohms. |
