When to replace coolant in Dodge Grand Caravan?
When to replace coolant in Dodge Grand Caravan?
You do not have to drain the entire radiator. Just open the drain valve and let out enough coolant so the coolant level in the engine is below the sensor. This would be a good time to check the condition of the coolant, and to replace it if the coolant is more than three years old (conventional coolant) or five years old (long life coolant).
Where is the radiator fan relay on a Dodge Grand Caravan?
If the resistance is greater than 1 ohm , repair the wire harness as necessary. If the Radiator fan control module has failed you will need to replace it with a new one there is no way to repair it. The radiator fan relay is located below the left front headlamp module. The headlamp module must be removed to access the relay.
What’s the name of the coolant temperature sensor?
Coolant temperature sensors are also known as engine coolant temperature sensors or ECT sensors. The principle working of this sensor involves the use of an electrical resistance which measures the temperature of the coolant.
What to do if your Dodge Grand Caravan radiator does not turn on?
Test the resistance of the wire harness between the PCM connector terminal 26 and the sensor harness connector. Also check for continuity between PCM connector terminal 43 and the sensor harness connector. If the resistance is greater than 1 ohm , repair the wire harness as necessary.

Where is the coolant temperature sensor located in the engine?
The Engine Coolant Temperature sensor (ECT) is located in a coolant passage in the engine usually near the thermostat. It changes resistance with the temperature. The Coolant Temperature sensor is critical to many PCM functions such as fuel injection, ignition timing, variable valve timing, and transmission shifting.
Test the resistance of the wire harness between the PCM connector terminal 26 and the sensor harness connector. Also check for continuity between PCM connector terminal 43 and the sensor harness connector. If the resistance is greater than 1 ohm , repair the wire harness as necessary.
