Are you looking to install a new thermostat in your 2017 Dodge Journey? Look no further! In this article, we will walk you through the easy steps to install a new thermostat in your Dodge Journey. You don’t need to be a car expert to do this – just follow these simple steps and you’ll have a new thermostat installed in no time.

What tools and materials do I need?

Before you begin, make sure you have the necessary tools and materials. You will need a new thermostat, a socket set, a ratchet, and a container to catch any coolant that may leak during the process. It’s also a good idea to have some rags or paper towels on hand to clean up any spills.

Start by making sure the engine is cool before you begin. This will help prevent any burns from hot engine components. Once the engine is cool, locate the thermostat housing, which is typically found at the end of the radiator hose near the engine. Use your socket set and ratchet to loosen the bolts holding the housing in place, and carefully remove the housing. Inside, you will find the old thermostat. Discard the old thermostat and replace it with the new one, making sure it is installed in the same position as the old one.

How do I install the new thermostat?

Next, clean the gasket surfaces on both the housing and the engine to ensure a proper seal. Then, install the new thermostat and reassemble the housing. Be sure to tighten the bolts securely, but be careful not to overtighten them, as this can cause damage to the housing.
