• Q: How to remove and install Cylinder Head in DOHC four cylinder engine on 1999 Ford Ranger?

  A: To remove the cylinder head, first, and foremost turn off the car's battery or disconnect the negative terminal of the battery and drain the cooling system. Then, you should take out the camshafts, then the fuel rail and injectors; pay attention to the spacers under the rail. After that you must pull the intake and exhaust manifold, take off the electrical connectors of the engine coolant temperature sender and the EGR valve which is situated at the rear of the cylinder head, additionally, the coolant hose of the EGR unit must also be disconnected. Also, you need to unscrew the cooling system bypass hose. Then, take out the cylinder head bolts, retaining only one for comparison purposes with the new bolts and then, with equal care, raise the cylinder head off. Before pulling off the cylinder head gasket from the engine block, turn it to possibly indicate the top side and after removal ensure it has been stored as well as comparing its shape with the new gasket for possible distortion. For inspection, you should make sure that the face surfaces of the cylinder head and block are free from gasket as well as carbon deposits by scraping the faces with hard plastic or hard wood scraper until all forms of carbon pick up are removed while being keen not to scratch the aluminum alloy. This should be done to cover the water, oil, and bolt holes on the cylinder block with adhesive tape and paper so as to avoid allowing carbon into the engine. Rub some thin layer of oil anywhere that piston might skid against the bore to shut out carbon, and once you have cleaned out each piston, brush all recognizable grease and carbon out with a little brush and wipe it off. The mating surfaces must be smooth so that there are no points on the surfaces higher or lower than others; slight imperfections can be filed down whereas, if there is suspicion of warpage, use a straight edge to determine the extent of the condition. To install, use sufficiently tackifier a suitable silicone sealant to two areas of the cylinder block, before fitting a new head gasket, with the appropriate side uppermost. Apply clean engine oil on the new replacement cylinder head bolts and align in position, apply hand force on all bolts while the final tightening of the bolts in five progressive stages must follow the specified sequence only. Reassembly is done in a reverse order to installation of the manifolds, making sure to replace the gaskets and fasteners for the manifolds and replacing camshafts and timing chain as directed, replacing all the fasteners to the proper torque, and gaskets. Last but not the least get all the hoses and wiring back in their right position, refill the cooling system, replace the engine oil and filter if necessary and visually checked all disturbed joints for signs of oil or coolant leaks once the engine is restarted and brought to its normal operating temperature.
