Anytime you replace cooling system components; like a heater core, it’s always a good idea to replace the thermostat at the same time. In most cases, the thermostat is one part that tends to wear out sooner than other cooling system components; so it’s a good idea to swap them out to ensure you don’t have coolant flow issues once you’ve replaced the heater core.
