An exhaust gas recirculation cooler may include a housing and a first wall. The housing may include an exhaust gas region, a coolant region, an exhaust gas inlet, and an exhaust gas outlet. The first wall may be fixed within the housing and may separate the exhaust gas region from the coolant region. The first wall may include a first region facing the exhaust gas region and a first tab having a fixed end coupled to the first region and a free end generally opposite the fixed end. The free end may be displaceable between first and second positions based on an operating temperature of the exhaust gas. The free end may be displaced in a direction generally perpendicular to the first region when in the second position.
