ENGINE COOLING
Replace time delay module, refer to
(para. 4-31).
Replace time delay module, refer to
(para. 4-31).
When checking coil resistance, use an analog
type multimeter.
For an accurate ohms reading, perform this
check when the system is at room temperature.
Heat will increase resistance, resulting in a
higher ohms reading.
Replace the control valve, refer to (para. 8-26).
CONTINUITY (RESISTANCE)
MULTIMETER
1. Set the voltmeter to an ohms scale of about 1000
ohms.
2. Connect the RED and BLACK leads to the
connections stated in the question.
3. Be sure to read the correct scale. Less than 5
ohms indicates continuity. For an open circuit, the
meter should peg full scale (needle all the way to
the left).
