Thermostats are designed to open at close at specific operating temperatures and may fail over time. Thermostats can become stuck in the open or closed position, causing coolant to flow without restriction and slow the time to reach operating temperature or become stagnant and overheat. Performance issues in your Ram, failure to reach operating temperature in a timely manner, and a malfunctioning or non-working heater may point to a thermostat that is stuck open. A thermostat that is stuck closed will typically lead to overheating and may cause a blown head gasket, warped cylinder heads, or other engine and cooling system damage. If your Ram 2500’s thermostat housing, thermostat, or thermostat gasket is failing, you may also experience coolant leaks and may notice a puddle of coolant beneath your truck. It’s a good idea to replace a failing thermostat and thermostat housing to prevent coolant leaks that can lead to engine seizing, damage, or failure. These step-by-step instructions and video will help you perform a thermostat housing and thermostat replacement on your 2002-2008 Dodge Ram 2500 the right way for a lasting repair.
