Welcome to our guide on replacing the thermostat in a 2017 Dodge Journey.

What is a thermostat and why does it need to be replaced?

A thermostat is a crucial component of your car’s cooling system. It regulates the flow of coolant through the engine to maintain optimal operating temperature. Over time, the thermostat can become stuck open or closed, causing your engine to overheat or run too cold. Replacing the thermostat is necessary to ensure proper engine function and prevent damage from overheating.

How do I know if my thermostat needs to be replaced?

If your engine is running hotter or colder than usual, or if you notice fluctuations in the temperature gauge, it may be a sign that your thermostat is failing. Additionally, if you notice a lack of heat from the heater or if your engine takes longer to warm up, these are all indicators that your thermostat may need to be replaced.

How to replace the thermostat in a 2017 Dodge Journey

1. Begin by ensuring that the engine is completely cool before starting the replacement process. Then, locate the thermostat housing on the engine. This is typically found near the top of the engine, connected to the upper radiator hose.

2. Next, drain the cooling system to prevent any spills or leaks during the replacement. Once the coolant has been drained, remove the radiator hose from the thermostat housing and then remove the housing itself to access the thermostat.
