An apparatus includes an exhaust gas recirculation (EGR) cooler ( 111 ) fluidly communicating with an intake system ( 117 ) and an exhaust system ( 109 ) of an engine ( 100 ). An EGR valve ( 113 ) is in fluid communication with the EGR cooler ( 111 ). A turbocharger turbine ( 103 ) has an inlet in fluid communication with the exhaust system ( 109 ) and an outlet in fluid communication with a vehicle exhaust system ( 177 ). A bypass valve ( 115 ) is in fluid communication with the EGR cooler ( 111 ) and the outlet of the turbine ( 103 ). A cooling system ( 200 ) includes a heater supply passage ( 222 ) and a heater return passage ( 224 ). A vehicle heater ( 220 ) is in fluid communication with the cooling system ( 200 ), wherein a flow path of coolant is defined between the EGR cooler ( 111 ), the heater supply passage ( 222 ), the heater ( 220 ), the heater return passage ( 224 ), and the engine ( 100 ).
