How to removal and installation of cylinder heads on Subaru Impreza?

Relieve the fuel pressure. Disconnect the cable from the negative terminal of the battery. Drain the cooling system and remove the spark plugs. Remove the timing belt, camshaft sprockets, and inner timing belt covers. Remove the camshafts. Disconnect the exhaust manifold from the cylinder heads. Apply penetrating oil to the fasteners before beginning the procedure and allow it to soak in for a while. Remove the intake manifold. Remove any hoses or brackets bolted to the cylinder heads. Loosen the cylinder head bolts in the reverse order of the tightening sequence. Remove the cylinder heads and the old gaskets. The block and cylinder heads are aluminum. Do not pry between the cylinder heads and the crankcase as damage to the gasket seating surfaces may result. Instead, use a soft-faced hammer to tap the cylinder heads and break the gasket seat. Cylinder head disassembly and inspection procedures should be performed by a qualified automotive machine shop. Installation: Clean the gasket mating surfaces of the cylinder heads and crankcase with lacquer thinner or acetone. They must be clean and oil-free. Install the cylinder head gasket onto the cylinder head locating dowels on the engine block. Install the cylinder head(s). Lubricate the bolt threads and washers with engine oil, then install them hand-tight. Use a torque-angle meter or mark the bolt heads with white paint and tighten the bolts. The remainder of the installation is the reverse of removal.

Subaru Impreza Cylinder Head

The main function of the Subaru Impreza Cylinder Head is to seal the combustion chamber and allow the fresh mixture in and the hot gas out. Many Cylinder Head has been made of lightweight aluminum that promotes better heat dissipation. Further, it allows for higher compression without detonation. Moreover, its reinforced areas let engineers contour ports for freer airflow and extra horsepower. The Cylinder Head is where the spark plugs, intake and exhaust valves, and coolant passages are located. If the Cylinder Head warps, cracks, or has worn guides, it may leak, misfire, or even cause a dead cylinder. When the head gasket fails between the block and the Cylinder Head, it will cause a loss of compression between the cylinders, coolant will get into the oil, or overheating may take place. These threats are minimized by the use of factory Torque to Yield head bolts that provide uniform clamping and must be replaced after removal. The older Subaru Impreza sometimes featured cast iron versions that were heavier, but contemporary models will generally prefer aluminum for a sharper power-to-weight balance and quicker heat shedding. In every case, the Subaru relies on a healthy Cylinder Head to keep every Impreza responsive, efficient, and dependable.
