An engine system having a turbocharger may include a cylinder head at which an intake manifold and an exhaust manifold may be placed, the turbocharger connected to the exhaust manifold to compress intake air by a first exhaust gas exhausted from the exhaust manifold, an intake line that may be formed between the turbocharger and the intake manifold through the cylinder head to deliver a compressed air compressed by the turbocharger, an intercooler placed between the intake line and the intake manifold to cool the compressed air, an Exhaust Gas Recirculation (EGR) line that recirculates a second exhaust gas that may be exhausted from the exhaust manifold to the intake manifold, and an EGR cooler that may be placed between the EGR line and the intake manifold to cool an EGR gas, wherein a low temperature coolant passing through the cylinder head cools the compressed air.
