To remove the cylinder head the following procedures should be adhered to, relieve fuel system pressure and joining the cable of the negative terminal of the battery. Suck the engine coolant out; thereafter, unfasten the intake and exhaust manifolds together with the camshaft. Stow the electrical connections and coolant hoses away and label and remove cylinder head connectors, and will also note that the water temperature control unit, on the 2010 and later model is removed at this time. To get it off, undo the cylinder head bolts in reverse and by a quarter turn each at a time to avoid warping or cracking of the block and carefully lift the cylinder head off the block using a crow bar when required. Disassemble any remaining elements coming from the outside for thorough cleaning by inserting a wipe. Sometimes to check the gasket surfaces for warpage, use a precision straightedge and look for cracks, and leaks from the head to the coolant. School that the mating faces for the cylinder head and block to be clean before fitting using a gasket scraper and brake system cleaner. For the two surfaces that are brought together during mating, examine them for signs of damage and debris, replacing bolts that have damaged threads. All cylinder head bolts need to be replaced on 2010 and later models, and engine oil need to be changed on 2014 and later models. Replace the components which have been pulled out from the cylinder head, properly orient the new gasket and properly place the cylinder head on the block. Damp the threads and under the heads of the bolts square with clean engine oil, and then engage and snug the bolts in the suitable order in compliance with the established torque values. In case of using new parts, it is necessary to apply the given torque sequence. Last but not the least, perform the installation process in the conversational order, replace the oil filter, fill the civilization, start the engine and look for leaks.
