Is it worth it to change the thermostat to 180?

How do you replace the thermostat on a Dodge Ram?

The thermostat housing needs to be cleaned up before you can reattach. Use a razor blade or a plastic putty knife and a rag to scrape off the old gasket and wipe it clean with a rag. Place a new gasket onto the housing. You may or may not wish to add some RTV sealant to the housing surface first; that is completely optional.
