The thermostat in a Dodge Grand Caravan is typically designed to open at around 195°F to 200°F (90°C to 93°C). This is the standard operating temperature range for most modern vehicles, including the Grand Caravan, to maintain efficient engine performance and fuel economy.
Here’s how it works:
- When the engine is cold, the thermostat remains closed, allowing the engine to warm up more quickly by keeping the coolant within the engine.
- Once the coolant reaches the designated temperature (195°F to 200°F), the thermostat opens, allowing coolant to flow to the radiator to maintain optimal engine temperature.
If the thermostat is faulty or opens too soon, the engine may not reach its proper operating temperature, which can trigger a P0128 engine code or result in poor fuel efficiency. Conversely, if the thermostat is stuck closed, the engine can overheat.
For more detailed information or replacement procedures, refer to the 2011 Dodge Caravan & Grand Caravan Service & Repair Manual, which offers guidance on the cooling system and thermostat specifications.
